Cons: "Older plane the tv panels were faded"

Cons: "Qatar airways claims to have inflight wifi. But it is not true because it did not work in either of my flights. Food could have been better."

Cons: "I found my seat a bit uncomfortable for this leg of the jurney"

Pros: "Everything really.They run the airline very smoothly and professionally from boarding to disembarking."
Cons: "They tempt you with so much food lol although some of the food wasnt too appealing.toilets very clean and seemed to stay that way throughout long 17hr flight.good leg room for a long legged guy like me.felt sorry for lady with two young children.She could have been allocated better seats."

Cons: "Nothing"

Cons: "The time of flight changed 1:30 hour erlier and we did get noticed we were about to miss the flight it’s so annoying but at the end we catch it"

Pros: "Polite crew, food was pretty good."
Cons: "Did not have the duty free item I pre-ordered. I asked the crew 4 times about it, four times because they said that they would check but they never got back to me to tell me that it was out of stock; until I pressed the issue."

Cons: "Did not make this flight. How can I confirm that my ticket is still valid for the return trip?"

Pros: "great service from flight attendnants."
Cons: "Old aircraft for flight from Doha to Nairobi, no personal entertainment etc."

Pros: "Overall a good service with good food."
Cons: "When flying from New Zealand to Doha, we departed Auckland at 15h25 and due to the time zone, most passengers body clocks would have been expecting sleep within a few hours. However we were flying West and thus into daylight. Sadly the window seated passengers were not asked to close their window blinds to block out the sunlight and many were left open. This made the cabin very bright and a difficult environment in which to sleep. Too much advertising before the on board videos, but otherwise content was good."

Pros: "Plane was clean and modern. Staff was very courteous. An overall pleasant flight."

Pros: "Good movies, Comfortable seats"
Cons: "Food could be better."

Pros: "They do not provide hotel service even in a 11 hour layover saying the ticket is pomotional. If that is the case, why they sell tickets on promotion? Cheap mentality"

Pros: "Qatar airlines had the nicest planes I have ever been on, not to mention the most beautiful and clean airport."

Cons: "Everything was disappointing"

Pros: "The aircraft from US to Qatar was upgraded and looked new. I love the new on demand video streaming, the touch controls are precise and better than previous version"
Cons: "I wish the airline was a bit more organized with boarding. I saw people with other zones boarding even when they were not called. The air hostess was friendly but I kinda got a feeling that she is doing me a huge favor when I asked for something more."

Cons: "The online check in system was down so we all had to line up to check in."

Pros: "I like the extra space between the seats that most of their airplanes had; the exception was, I think, the 767. The crew went above and beyond to take care of your needs and always had a smile on their faces."
Cons: "The check-in process, leaving Bangkok and leaving Doha, was horrible. Why do I have to wait until 3 hours before my flight departs to check-in and get my boarding pass? This made for long lines and took about 2.5 hours to get a boarding pass in Bangkok"

Pros: "The food was very good, I liked vegetarian options and my stomach doesn't hurt after the plane food as usual. I like the bathrooms clean and nice smelling soap. The crew was very attentive and eager to please their guest but consistent and insisting on the safety rules (belts buckled up and seats in upright position)"
Cons: "There wasn't many good options for entertainment. Only a couple new movies although I liked the TED talks. Also I liked the plane but I wish there were some foot steps and more comfortable head support on the seats. I didn't like also strange option for Golden members in economy seats to be able to "order" food before regular people. There were only 3 options and everyone had the same choice. So basically all that crew does is just asking which course gold members want an hour before serving. It seemed silly with no actual benefit."

Pros: "Had a great experience with this flight"
Cons: "Nothing"

Pros: "same"
Cons: "same"

Cons: "horrible customer service at Doha Airport"

Pros: "Nothing"
Cons: "In their Business Class they only had two shower room and they wait was 7 hours! I now totally dont trust Kayak and it's ratings. Qatar Airways sucks!"

Pros: "Much better knee space. Excellent flight, good service..."

Pros: "Comfort and service"
Cons: "Food breaks should be more"

Pros: "The crew was excellent in their mannerisms, efficiency, service and never ending smiles."
Cons: "The flight was not overly crowded and many of the passengers were seated with three people per set of seats while others were seated individually and able to spread out with much more comfort. I felt that when the flight crew saw this they could have made everyone much more comfortable by switching people to two people per row thus giving them more room especially on such a long flight."

Pros: "Stewardesses were more helpful on this flight than we had experienced on the previous flights. However their resources were limited. landed safely."
Cons: "Food on the four different flights (from DFW to Doha on to Cape Town and then from Johannesburg to Doha on to DWF) was not good at all. Timing of meals, food all below expected. One flight attendant trying to serve both meal and drink to each person took a lot of time. Snacks offerings were almost non-existent. Those of us traveling on three connecting flights with no time to purchase food nor water had a rough time of it. Would not fly Qatar nor connect in Doha again unless absolutely necessary."

Pros: "It was a good flight. I'd give it 4 of 5 stars."

Pros: "It was not a full flight. It was ok."
Cons: "Well, I noticed when the person in front of me reclined their seat, I had a hard time adjusting the entertainment screen so I could see it properly."

Pros: "Nothing really"
Cons: "Food was really bad might as well have junk food."

Pros: "Awesome staff, super delicious food. Missed the flight, but airlines covered stay in Hotel in Doha. So we hot extra vacation day In Qatar with nice food and stay in a country we have never been"
Cons: "We have missed connecting flight from Doha to Oslo because of bad weather and had to stay in Doha, Qatar for 16hours. But airline took care of all passengers, organized 5*hotel in heart of Doha with luxurious food in the hotel restaurant"

Cons: "A lot of plains departing from gates grouped together and we had to sit on the floor while wainting to board after we have been travelling for 18 hours. Obviously with no crowd control boarding was a mess."

Pros: "The Chicago flight was more than hour late so had to miss my cincinnati connection. Had to wait for 4 hours at the airport to catch my next flight- making the long journey even longer. No priority lounge access provided to make up for the delay. Qatar never getting my business again."

Cons: "I had to ask for wine to 3 different hostess's"

Pros: "Good"
Cons: "Okay"

Cons: "Expect more then OK from Qatar."

Pros: "I was upgraded to business class for the first time in my life. The food was good, and plentiful, in both classes. The stewards were accessible and friendly, the seats were comfortable. The movie selection was good"
Cons: "I was trapped in the window seat, because my neighbors were sleeping. Not Qatar's fault"

Cons: "Not allowing water on the flight made it extremely long and unbearable."

Pros: "Crew"
Cons: "Everything else"

Pros: "Easy booking of flight"
Cons: "The gate changed in a Dubai without proper announcement, Ground staff should have visited the passengers waiting in the gate waiting area that was printed on boat pass and inform them to new gate. Instead they charged the passengers with no show fees and delayed departure for another 12 hours."

Cons: "Better inflight entertainment"

Pros: "Checking-in was super simple, and speedy. All the staff I had contact with were very polite and professional"
Cons: "I had exhausted the entertainment system before I finished my first leg of the outbound journey."

Pros: "Liked everything esp the luxurious interior& the comfort of the business class"
Cons: "Nothing"

Pros: "I had a fast and easy check-in at Denpasar airport. In flight service by cabin crew was very good, as I normally get in the business class at Emirates. Flight left Denpasar on time and arrived in Auckland some 30 mins early, which was nice. Enjoyed a late dinner - the mie goreng ayam was particularly tasty!"
Cons: "In the past on overnight flights Emirates I have received a pyjama set in the Business Class, which made it very comfortable to sleep. But this time this was not given, so I had to sleep in my day-wear, which was a bit uncomformtable."

Pros: "Obviously Biz Class is a great proposition for a flight of this length and once again the experience was a good one. Staff are always friendly and very attentive."
Cons: "We are not big eaters but when you leave at 10am then a lunch and breakfast is a bit of a stretch and even with light snack options we found ourselves hungry. Breakfast was not too flash"

Pros: "The crews"
Cons: "The wifi is bad the food is bad im in business class"

Pros: "All of the above"
Cons: "Nothing that i didn't like"

Pros: "The departure and return flight time, for the price I paid, I felt like I was in more than an economy flight. The meal, the baggage quota, the entertainment. The time flew because by the time the movie had finished, we were starting to descend. I will always look for this flight with Emirates. There is no other flight in comparison, in what you get for your Buck. I believe that other Airlines, ie., Qantas, Virgin Aust, both give you a flight and service, for nearly the same fare but you only get 7kg luggage, no meal just the basic entitlement, tea/coffe/water with a biscuit or something like that and NO ENTERTAINMENT, NO COMPARISON!!!!"

Pros: "Everything was good especially the spacious seats and food"

Pros: "Footrest would be good for a long haul flight."

Cons: "Noise of serving some people dinner in middle of night interfered with sleep. Deep dip South meant no internet for much of the flight lots of noise and inconvenience trying to fix Tvnz for (rude) lady in front"

Pros: "Travelled Business Class - a great experience."
Cons: "Slow to board."

Pros: "Really liked the long journey. Was a bit nervous given the 15 hour flight but was pleasantly surprised. Service was good as well."
Cons: "The crew were really young and not very talkative."

Pros: "The plane was spacious and we had really good seats , next to the toilet and wall in front of us. Super, as we were traveling with a toddler and he was able to sit on the floor in front of us and play with his toys. Food came out promptly and was tasty. Loved the goodies for the kids, little blanket and scotch pad."
Cons: "The delay in boarding! It’s hard work when traveling with a toddler."

Pros: "Good facilities, food and entertaniment. Seat comfort not so good."

Pros: "The service, food and boarding were all excellent. It brought back the joy of flying like what used to know in the 80s."
Cons: "None"

Pros: "The food was good and the service was great. I also had a great seat in the front row."
Cons: "We were delayed by over 2 hours We had no where to park when we landed so we had to wait for buses to take us toche terminal There was no new and exciting movies that excited me"

Pros: "Extremely quiet plane since they placed people in front of the half empty plane. Great plane food and internet access, limited to text but still incredibly useful to text people from the air."

Pros: "On time, very helpful crew and overall experience was fine"
Cons: "Food was not upto the mark and one always expects something better from an Airline like Emirates"

Cons: "I checked in online, but when I went to drop my bags there was about a 20 min delay. the agent needed to make 2 phone calls and conference with 2 supervisors. All this without letting me know what was going on."

Cons: "Very late. Caused us to miss outlet rental car. Left us stranded at the airport."

Pros: "Great entertainment system. Lots of leg room best airline"

Cons: "Nothing"

Pros: "Everything"
Cons: "Nothing"

Pros: "The entertainment system"
Cons: "Everything else"

Pros: "Plane was the old type and not the new one that I got when flying out. Still the seats were comfy and reclined. Also the entertainment system has been updated and was brilliant."
Cons: "The food could have been in more regular intervals. I was very hungry by the time we got the turkey sandwich and chock chip cookie."

Pros: "Check-in was efficient and staff were extremely helpful. Flight itself was comfortable, food was actually tasty, and in-flight entertainment was great. Overall an amazing experience compared to US carriers."
Cons: "Boarding was a bit disorganized."

Pros: "I enjoyed my first time flying with Emirates from Australia to New Zealand The checking in was quick, easy and the staff were friendly. The crew were polite, and friendly with excellent customer service. Refreshments and Entertainment were first class. I will be flying Emirates from now on."

Cons: "Nothing"

Pros: "Up to date movies"
Cons: "The boarding in riyadh airport was crowded because it included all economy class travelersat once, it should start from A category till the last group. This should be rectified."

Pros: "everything from service, food, to entertainment. Keep up the good work."
Cons: "Seats were a bit small, if I had more room it will be perfect."

Pros: "Comfortable cabin, attentive crew, if somewhat aloof. Food okay, but better than a 2 ounce package of salty pretzel mix for $3! All in all, quite good."

Cons: "Confusion with wrong menus being handed out - on 2 flights!"

Pros: "Crew were lovely"
Cons: "Extremely overweight passenger next to me. It was awful, her body was in contact with me the entire flight. The most uncomfortable, hot, smelly, awkward flight Ive ever experienced. Its time you charge for 2 seats for people that are the size of 2 people. Not fair to other passengers to have to be so inconvenienced and extremely uncomfortable."

Pros: "Started my Movie on the Ground before takeoff"
Cons: "Flight was delayed and there was absolutely no announcement with everyone lined up at the scheduled departure time. Communication on the delay was non existent. There was one announcement made 10minutes after boarding was suppose to commence to say the boarding will be delayed. No details as to why, approximate time."

Pros: "A380 is so quiet and smooth. Nice to be up the front of the plane, albeit on the lower floor in economy."

Cons: "The flight was good, however I was not able to check in online due to British airways website issues. The entertainment touch screen is not working properly,needs some maintenance."

Cons: "Seat 26 beside exit but cold air passing through the door/fuselage made the overnight flight very cold and uncomfortable. Very disappointing."

Cons: "Overbooked flights led to a missed connection resulting in a 12 hour layover"

Cons: "More legroom."

Pros: "I flew with my sister who has disability. Check in was very smooth and the Spanish lady who checked us in at Heathrow airport took our hand luggage which was really nice as we could just take care of our wheelchair."
Cons: "BA should consider to serve complementary coffee and tea on board. Such a little thing, but could make a huge difference."

Pros: "On time service, quick to board ."
Cons: "I’m surprised by now that British airways don’t provide any food for children onboard. A cheese and mushroom toastier is not exactly child friendly"

Pros: "Very friendly"

Pros: "On time"

Pros: "The smooth journey in the sky"
Cons: "The fact that BA flights even morning ones are always behind schedule"

Pros: "Very accommodating flight crew, food and drinks very good, Entertainment excellent"
Cons: "Printing boarding passes is difficult."

Pros: "good service. crew speaks English."
Cons: "cost of baggage"

Pros: "Staff very pleasant"
Cons: "Old 747 poor video poor seats old toilets full of dust these plans need to be retired"

Pros: "Great entertainment choices"
Cons: "Slow crew. Same good choices as flight just before"

Cons: "paying over £200 for a one way 3 hour ticket and having to buy food on the plane."

Pros: "It was short and fine"
Cons: "None"

Cons: "Flight was delayed 30 mins to Dublin and flight was delayed 1 hour back to London. No free meals provided"

Pros: "The A-380 is outstanding. Seats are good, even in economy. Entertainment system is great."
Cons: "It seems to me that boarding by Groups has not helped in the least bit, instead it has made things slower. It's bad enough that the charges and limitations on luggage have forced everyone to try to board with their suitcases... The group system just makes things worse. I recommend BA compares itself to Lufthansa, Swiss, Qatar, Thai, whatever, and avoid trying to match Easyjet and American Airlines on service levels. Oh, and there is no excuse for long delays and cancellations in the most important airport in Europe. At least not for a simple dusting of snow."

Pros: "Crew was very nice and helpful"
Cons: "Did not get the seat according to the seatplan.I booked exit row seat 30..got 30..but exit row was 28."

Pros: "Ice cream. Nowday, on flight food is hard to find the tasty one."

Cons: "Sitting on the tarmac for to long...."

Cons: "After an 11 hours wait to connect my flight, they still managed to leave one of my bags behind. Not cool"

Pros: "The crew was very attentive, serving food, drinks and water very often"
Cons: "BA made me place my laptop and Ipad in the checked bag, preventing me from working on my computer for the next 20+ hours until my final destinations. Ridiculous policy! Very rude immigration and security people at Riyadh, I realize this is not BA's fault, but it was very annoying. Second level search of my carry-on bags at the gate very invasive procedure."

Pros: "The crew was really nice overall and the entertainment system was adequate. The main meal was decent too."
Cons: "The flight was late (I was warned online but there was denial at the airport and gate) and further delayed in flight so I missed my connection. I didn't like the pods in business class. I had a forward facing seat at least, which are all by the aisles. They seemed narrow. I didn't sleep (never do). The breakfast was a bit lame. Getting into buses from the plane IS lame. It took a while to get to the terminal."

Pros: "Great service"

Pros: "As always, a great flight."
Cons: "Nothing I can think of."

Pros: "Nothing really exceptional"
Cons: "Flying frequently with Emirates and Saudia rises your standards! seats, privacy, food, service on British airways are way behined!"

Pros: "Timely boarding and arrival. Friendly service."
Cons: "The entertainment was not really good - very few movie options. Food was so-so, not really anything as good as it can be."

Pros: "The cabin crew were exceptional. One flight attendant in parifular was extremely helpful to us in helping place our carry on luggage in the overhead compartment. I did not get his name but he told me he was from Spain."
Cons: "- Landing cards were only distributed 20 minutes before arrival. The seat belt sign was already on. So, I could not use the food tray to fill out the cards. I tried to use the magazine to put under the landing card, but there was some turbulence and I could not fill out the cards n the plane. Cards should be passed to passengers an hour after Akef off. - no gifts given to kids like small games or coloring crayons to keep them busy. - food took hours to serve and was not comparable to BA's image. - the water pressure in the toilet's wash basin was too strong and was splashing all over my cloths."

Pros: "Plane ldeparted and landed on time. Plane was nicer than expected but not the same quality as Airbus 320"
Cons: "Immigration was severely understaffed for number of people waiting Took an hour to process 50 people. Crew member unhappy by seat swap as had special meal request. Had moved only one seat to the left to help other passenger out."

Pros: "Entrees were OK"
Cons: "Not nearly enough snacks. They were pretty much out in business class half way through the flight"

Cons: "Entertainment selection was poor. Also breakfast was bland"

Cons: "Wasn't any food left couldn't use cash ,couldn't use American credit card I received water only after we almost missed our plane because 3 times baggage layer belt broke down, I was hungry and wanted a cocktail or soda ."

Pros: "Very full flight but all went efficiently and smoothly. Staff excellent as usual."
Cons: "Nothing I can think of."

Pros: "The pilot was gentle landing the pane"
Cons: "No complimentary anything, not even water"

Pros: "I liked everything! Free drinks, movies on demand on the seat-back screen on the seat in front of you... comfortable seats. I would definitely fly BA again!! (The American Airlines return flight was a bit less desirable in all categories. Comparatively, BA was awesome!)."
Cons: "Not a thing!"

Cons: "did not have vegetarian food display of journey on 3d map a very very poor one - poor screen control, graphics , speed"

Pros: "nice plane and seats left on time"
Cons: "no water or coffee offered unless you paid for food"

Pros: "The crew was wonderful , the seats very comfortable , breakfast very reach I felt my self booking first class not economy It is the best trip"
Cons: "Nothing"

Pros: "the plane was comfortable even when full, although there are only two toilets for over 200 people in coach which makes it difficult sometimes"
Cons: "I used to live in London in the past, and commute with BA routinely, without any considerable issues. With this in mind, I booked this flight through the american site as I now live in the US. Big mistake. Even though I'm still a BA member and I checked in 24 hours prior to departure on the minute, I had no way of choosing a seat, in fact I had to pay to change my assigned emergency exit aisle seat. Secondly, there was a 5,5 hour delay, due to fog, which affected BA but not Easyjet or Aegean flying the same route at the same time, leaving me looking at all the other passengers taking off while I waited at the airport without any notice from my company. This resulted in me getting a debilitating migraine, for which I had to request painkillers on the plane. For anyone who hasn't done this before, despite how helpful the staff are, there's always "procedure" to be followed and papers to be signed before obtaining tylenol. Finally, when I contacted BA customer service to request a refund for this trip, considering if I had booked with any other airline I wouldn't have gone through all that, I was told it was my fault for not carrying painkillers and they "absolutely do not reimburse" such situations involving the weather. All in all, this was the last BA flight I will ever book and I am happy to go back to the US where customer service has an actual meaning and passenger wellbeing is always a priority."

Pros: "The departures were on time or close to it"
Cons: "On the return flight back from London to Las Vegas, I sat at an economy class aisle exit seat on a 747. The flip up TV set wasn't working. One flight attendant initially offered to move me to a cheaper less desirable seat, which I declined. I asked for at least an exit row seat of any sort. A second (more senior) flight attendant then promised he will either fix the TV (by resetting it) or find an acceptable alternative so I "won't need to go the entire flight with a TV." But he never returned and the TV never worked. I didn't fuss because I slept and read instead, but I thought this was a poor follow up and follow through on his part."

Pros: "Great customer service"
Cons: "One of BA system was down which did delay us"

Pros: "Arrived early and smooth flight !!!!"
Cons: "Service was good a quick flight ."

Cons: "Damaged suitcase"

Pros: "As a first time flight using BA, I was very impressed, and felt I received good value for money."
Cons: "I did not like the policy of paying to assign yourself a seat ($51 per seat) unless you do it online 24 hours prior to your flight - which I chose to do. I understand in the current business climate of paying for better seats, but nickle and diming plain Jane economy seats is unacceptable."

Pros: "Nothing special"
Cons: "Same seats and legroom as in coach. Differed from coach only in that a tray occupied the middle seat rather than a person."

Cons: "They lost my luggage!!!"

Pros: "The crew s oustanding. They were courteous, helpful, very professional and made the flying experience a pleasure for my family. With respect to the Miami ticket agents, there are 3 people I want to highlight for excellent service. Denise, who courteously accommodated our family and rescheduled our flight as needed, another young lady who checked us in. She was sensitive to our party of 5 and was extremely pleasant. The check in process was chaotic at best and she helped make it a pleasant experience. The person is Diane, the manager at the Miami airport. She helped bring order to a completely disorganized check in process and ended up personally escorting us through security toe sure that we made our flight on time. Diane is an excellent leader."
Cons: "The check in process was completely disorganized, due to a cancelled flight from Miami to Heathrow the night before. And there were 3 scheduled flights already that people were checking in for as well. There had to have been at least 600+ people in line to check in, plus those from the night before. The Miami airport doesn't have kiosks for passengers to easily check in and bag drop, which doesn't make sense in such a large and busy international airport. That would have made a huge difference in this case. Also, we paid for our seats to select them prior to 24 hours and we ended up not sitting together."

Cons: "Very little room in my seat. No fot room and then the person in front put his seat all the way back. Very uncomfortable."

Pros: "overall great!"
Cons: "food issues for lactose intolerance, also TV screen very difficult to operate."
