Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

It was very good experience on board to Sydney with SQ.

Everything was great keep up the good work 😁, can't ask for more.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Loved the staff. The economy seats could have been bigger.

I liked the service, the menu, and the comfort of the seats! Even tho we were seated by the bathrooms, the reclining seats and movie selection was very good, my husband and I didn’t mind at all

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

It’s a two prop flight so I had problems with my ears on re- entering ! But otherwise fine

Wheelchair assistance to move through the terminals and to/from the plane door was excellent. No vegan snack on the flight, only something with salami and cheese in it.

The old Plane had not been cleaned properly in a long time.

Planes was old - business class seats looked like they were installed in the 80s

Our baggage didn’t arrive with us on the plane. Need I say more?

I have taken this flight many times. It is ALWAYS late. Every time there is significant delay (1-3 hours) before boarding. It’s very consistent. Even after boarding the expected landing time was delayed twice. The seats are very narrow and cramped. Food is barely editable. Considering an economy ticket often costs about $2,000 it’s one of the worst services ever.

Gate information deliberately delayed to only one hour B4 flight, lack of info finding gate.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

I paid for business class…. And was counting on the usual packet of toilettes to be provided. They were not because not enough were brought on the plane so they could t give to some and not all. So no tooth brush nor eye cover. Then NO coffee since there was no hot water. The lay I er too short because of delays and my luggage didn’t make the next flight!! It is now a day later and I am awaiting to hear if my bag has arrived. Very inconvenient!. I suppose I need to be glad that I spend over $4000 since I doubt those in coach or premium economy even made that next flight..Heathrow is the worst.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

LCY airport is an amazing airport and I love the flight from LCY to FRA with BA. Efficient, easy, comfortable and great luggage allownace with BA. I iused to fly predominantley LH, but the service and price - benefit ratio of Lufthansa has deteriorated a lot over the last 5 years. Whereas BA keeps an excellent service level with friendly staff.

Delayed flight due to lack of crew caused me to miss my connection

Boarding was chaos. They did not board by group number and it was a free for all. We had a young child with us and were expecting pre boarding. Crew announcements were also poor as the crew member was speaking far too quickly to be able to hear what they were saying.

I enjoyed the flight. I did find it strange that when I arrived at my seat although I had paid for a window seat that I was assigned a middle seat. Thankfully I was between a couple and they wanted to sit together. Please do a better job with this BA!

One if not the best Airline I have traveled so far. My only complaint is that flights where delayed.

It would be great to have at least two choices for a food, instead of just plain pasta 😏
