Pros: "New aircraft"
Cons: "The willingness to provide a better quality service by the entire cabin crew and improved food quality."
Cons: "The rebalance was worst I've ever encountered I was actually scared I prayed many times 4 yo get home safely I was not impressed with my last flight n also why were We delayed coming from manila we turn back many times n I had only 50 mins to catch my flight to Perth if we had landed wen we should hv I'd hv time to buy some gifts I'm.glad that Philippines airlines will fly direct yo manila from Perth come March n I'll use them from now on as it's a few times in the years gone that things has happened to me I forgave ur airline but now i not need to as hv other airline to fly n my darling come here 3 or 4 times each year but will use Philippines airlines URS sincerely Trevor frahm"
Pros: "Overall, the staff was amazing, so as the food and cleanliness"
Cons: "The space between the seats in economic seat"
Pros: "Yes and yes"
Cons: "Not sure because I have never had a better experience."
Cons: "Entertainment including games such as backgammon, black Jack, and poker are not available although they are on every other airline I used with high quality game programs that are clos to live games"
Cons: "We had to go through security after coming in from international and I went through a biometric scanner which I’ve done 100’s of Times I was very unnecessarily felt up for 10 minutes. I had shorts and a T-shirt on, and was pretty sure after the 1st round of groping that there was nothing there"
Cons: "Cramped seats, no leg room, horrible food, stupid COLD snack!"
Pros: "The crew, their professionalism and wide variety of entertainment."
Cons: "Air-conditioning was not working properly in the cabin and it felt warm. Seats are a tad uncomfortable and not wide enough on the 777."
Pros: "Handset to control screen didn’t work. Airline reimbursed me with $75 voucher for inflight duty-free shop."
Pros: "Lie-flat seats in business class"
Cons: "4 hrs delay due to failure of Singapore Airlines to have a working plane on site at the appointed time. Even worse: chaotic deplaning with one crew member telling passengers to deplane and another yelling at them in the bridge for doing so. A mess of lines trying to get a new boarding pass for a rebooked missed connection—at the front of the line the agent said oh, you need to wait in this other line. Agents had no clue where to direct passengers and gave incorrect directions that necessitated more waiting. No updates to new flight time in the business class lounge. Once the flight was in the air, service was terrible. Attendants would ask for orders, then never bring them or bring the wrong thing."

No refunds for flights that I could not take due to Covid restrictions

Pros: "The crew were lovely - friendly and polite!"
Cons: "The delayed departure- but I truly understand that it was beyond the control of the company as the delay was weather related."
Cons: "Waited 55 minutes for baggage claim in Auckland. No reason given. I expect better service from Air New Zealand even though I understand the baggage handler’s are different group"
Pros: "Movies, texting other seats, requesting food and water from my screen"
Pros: "Kind staff, long flight but the attendant were super kind"
Pros: "All good"
Cons: "It was very cold so the cabin could have been warmer"
Pros: "Airline is pretty good"
Cons: "I had a horrible experience booking with Kayak because normally I should be allowed two bags to check in but I was only allowed one because I booked through kayak."
Pros: "They took care of you. Meals were good. Excellent airline"
Pros: "Bulk head seats were great."
Cons: "It would have been nice if it had not been almost 2 hours late!"
Pros: "Seats rows seemed to be more distance apart than other airlines. Flight was actually done by Air New Zealand rather than Cathay Pacific. Check in at Auckland airport was very quick and highly automated, however, our gate was not posted till one hour before the flight, so we did not know where was the best place to sit and wait."
Cons: "Food was mediocre. Coffee and tea were like warm or cold."

No individual entertainment screens on this flight. Would have been nice to know beforehand.

Cons: "Love that they fly an a380 into christchurch - a bit overkill but was told it is cheaper to overnight the plane in christchurch vs Sydney or Melbourne"
Pros: "The crew could be less curt and more engaging. Coming from Guest Services in hospitality, leisure and tourism it is obvious that body language and sincere engagement stands out. That wasn’t the case for the Qantas flight."
Cons: "I was unable to checkin or select seats. Understandably this is governed by immigration laws and not airlines but on three attempts I was able to pay for the seats without a receipt only to learn later that the charge did not go through. A little bit of transparency never costs anyone."
Cons: "Having back up/extra meals for people with dietary requirements as they may not have been able to request them."
Cons: "There was no organization for those of us that were moved to that flight. Shifted from 4 different lines and luggage was not sorted out after customs. Our luggage didn't make it on our flight since someone said since it said CVG, it would be fine. It wasn't."
Pros: "Fast boarding and great entertainment."
Cons: "Food was sparse and water hard to come by. The ability of passengers in front to deeply recline their seats made the flight uncomfortable and claustrophobic."
Cons: "No back-of-seat screen, overhead screens lacking enough contrast to see much. No matter, I looked out the window instead!"
Pros: "Great Business Class Lounge close to departure gate."
Cons: "Connecting from a domestic flight with Virgin Australia to the International Terminal carrying 5 large pieces of luggage was a bit stressful and complicated. Train or Bus ? Lots of Lifts up and down. Boarding security was excessive."
Pros: "The crew was spectacular. Could not have been more friendly and helpful. Went out of their way to provide great service. The food was great, especially the breakfast!"
Cons: "The coach seats were wide enough, but a couple of more inches leg room would have been better."
Pros: "The seats are comfortable and the service is first rate. Best airline out of Virgin Australia, Air New Zealand, and Qantas based on my 3 trips to New Zealand. It helped that we were on an A380 and because of the lack of the plane being filled both my travel companion and I had 3 seats to ourselves to stretch out. In economy, without that, nothing would have made the trip bearable. That said, the food was good, the entertainment options good, and the after hours water/liquid/snack options were quite good."

The Plane is spectacular. Immaculately clean like showroom clean. Beautiful interior etc etc. However it took 45 minutes for the first drink to come out and nearly two hours for dinner to be served. On a flight that took off at 10.45 that is not fun. I actually fell asleep eating my main course. The food is just OK. Really needs work. Drinks where tiny pours so constantly needing filling up. The new where very very sweet people but there was this air of confusion about them. As if it was their first flight. It didn't install confidence in me if there was an emergency. I actually flew on to Sydney with the airline on the same plane and the crew where totally all over it!! Super on the ball, so I may have just got an inexperienced crew?

Pros: "Comfortable seats and great on board hospitality"
Cons: "Boarding in Nadi international airport for Fiji airways is boarding the passengers from the back of the aircraft first which was different for me"
Pros: "The crew was great. Food was good."
Cons: "They SERIOUSLY need to update the entertainment on the plane. If everyone has to watch the same movie, which prehistoric in itself, can they at least make a recent movie and not one from the 80's??? They played 2 movies, both from the 80's!"
Pros: "The crew was really friendly."
Cons: "The entertainment options were really limited. Movie options were mostly older movies."
Pros: "Seating was good for an economy class redeye--the seats (A330) reclined well, though the seat in front of you reclined into "my space". Okay food, polite, efficient attendants, complimentary wine or beer with meals."
Cons: "Two-pronged headset outlet made using my own headset unworkable. Their headsets aren't very good."
Pros: "Very welcoming crew, kept us informed of any changes"
Cons: "The seats are old, no entertainment, really not the quality I expected for an international flight"
Pros: "Good price but not too good services"
Cons: "Better service management to avoid delay flight. Invest in better quality seats for passengers plus better entertainment value to increase more passenger"
Pros: "The crew were very friendly and professional. Economy seats were slightly better than most, but the configuration of the 2 seats was good 2 of us to have our own area. Food was good."
Cons: "Boarding was hectic and unorganized, but functional. Movies/TV shows were limited compared to other airlines. I am taller so seating in any economy seat is cramped at best."
Cons: "I arrived in transit from another flight, no representation to make check in. I needed to wait for gate to open before I could check in. then there was no time for the airline to recover my Bag. Do no us this airline in transit"
Pros: "I was excited to come back to the USA after a long vacation. When we arrived at the airport, the security started asking me questions immediately even before I checked in. They demanded I show them the ticket before it was even printed. When I explained that I was trying to check-in for the first time. They told me I was going to be reviewed upstairs and put a sticker in my passport. I proceeded to check in and just walked thru the normal security measures. After scanning my bags in security, I discovered there was no security meeting and proceeded to my gate. After the gate, everyone in line was subjected to a second security screen. This was a manual search and all articles were removed and repacked again. Then we proceeded to the plane entry where everyone needed to verify passport and ticket again. Later in the flight, I was having indigestion problem from my documented medical acid reflux problem and asked for a cup of water. He said sure and walked away. He never came back again.10 minutes later, I pressed the attendant call button again. 10 minutes later and no one came over. 15 minutes after that Albert came back over and said, "I see you have your call light on, please put your seat back up again." I can complied and he immediately turned off the light and walked away. 10 minutes later, Albert came by with the water cart and parked it right behind my seat. He proceeded to hand out water to everyone behind my seat. 30 minutes later the water cart arrived and I finally received my water (75 minutes after I asked!) Thanks Albert, I'll be following up with your management to see that disciplinary action is taken."
Cons: "See above. The above problem caused me discomfort, pain, stress."
Pros: "no amazing crew and no warm and fuzzies"
Cons: "Pre bought meals and wasn't permitted hot chocolate for children. Eventually given and nothing said. On the journey over hot choc offered. Not a big deal. I think you fall down in customer service by not supplying a little like coffee and hot choc and a free snack. Possably will avoid flying Jetstar again. Service is paramount. And no entertainment available because it wasnt a long haul just a short haul though international. Mmmmm no to Jetstar i feel. I own a resort and i know what customer service must feel like."
Pros: "We arrived to the airport 2.5 hours early which was too soon to check in. Instead of making us wait, the Jetstar attendant offered us an earlier flight. Very accommodating and thoughtful! Thanks so much Jetstar!"
Cons: "N/A"
Pros: "After we finally got checked in after standing in line (1.5hrs), due to the previous night's storms (& finally had to argue with staff, after they had already announced final check in)- everything else went off without a hitch. The flight operated- a plus when compared to my two previous JetStar bookings."
Cons: "I organization of staff who had told us at "we would be fine" in the line we were in- only to be hurried to the "final check in desk" and have the staff there tell us to get back in line."
Pros: "I did like the price of airfare. The aircraft was clean."
Cons: "No legroom, no complementary snacks or drink. No entertainment."
Pros: "Leg room was sufficient, boarding fast and plane next to new"
Cons: "Luggage limits- but that’s life!"
Cons: "Be sure to pay for checking baggage when you purchase your ticket. I didn't because I thought we could carry our two small roller bags on board. We were not allowed to and had to pay $120!"
Pros: "Courteous staff from checking in to departure. Flight was short but on time and smooth. Perfect!"
Pros: "The base price is very low. We were slightly over ~1kg our allotted 7kg/passenger and they let us go."
Cons: "No entertainment on the flight whatsoever. The space in the seat is a bit tight, doesn't recline very much either."
Cons: "We had a tight connection and the flight crew could care less about if we made it off the flight in a quick and efficient manner."
Cons: "Pity we paid for Qantas but still has JetStar service with pay for all drinks and food."
