Airline reviews

The A350 3-3-3 configuration is cramped and uncomfortable. The seats dig in to the contact points with your body. The aisles are now too narrow for passengers and crew to pass with ease. I was in an seat but the passenger in front was laid back for the majority of the flight meaning I had to do the same. There was a kid in the seat next to me who wriggled all night which kept waking me up. If fact there were too many kids on board - why weren't they at school? Babies crying too. It was like a Kindergarten. Singapore Airlines in barely getting above Jetstar these days. It seems to have gone downhill since merging with Air India, The evening meal of fish and noodles was average. the morning breakfast of a pie was poor. At least the alcohol flow kept some sanity. The film choice was good, but I'd already seen the good stuff on the way out. The crew are still amazing and the service set the airline apart. A shame about the packed plane with inconsiderate passengers.

Food was excellent.. better if there are more movies selection.

Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

Service excellent would chose Singapore airlines as my first choice

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

The male traveller seated in the row in front diagonally opposite my husbands seat across the aisle as soon as the seatbelt sign went off moved across the aisle into the seat in front of my husband for the entire journey from London to Singapore he had his seat reclined and pushed back and the seat touching my husbands knees for the entire journey from London to Singapore. very uncomfortable for my husband.

More Baggage limit Alternative of virtual check in at airport , prefer personal touch with “real person”check in counter for baggage drop

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

Horrible!! The WiFi was not working, the food was awful

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

Delayed 30 mins Forced to check in my carry on luggage

I have been traveling with visa for 25 years and this was the first time when we find out in Miami that my children’s connecting flight were overbooked and been canceled by Swissair from Zürich to Budapest. The results of that they re booked us at the Miami airport. The new route was Miami to Zürich ,Zürich to Amsterdam, Amsterdam to Budapest. We had over six hours layover in Zürich and arrived to Budapest nine hours later. There should never be in a situation where a ticket that I purchased over 7 months ago was sold to somebody else and instead of removing those two people we had to do this journey, I’m contacting customer support and requesting a refund shortly.

No fault of the crew, but the the rear lavatories were closed the entire flight. The front lavatories were blocked off for the first part of the flight by the food cart. Then some minor turbulence occurred so the fasten seatbelt sign came on for the second part of the flight. Heroic containment engaged! It was not fun.

Flight was late and crew were unwilling to help with information on connections. Call light had been on for 61 minutes without tesponse.

Motivated and friendly crew on a somewhat dated but well kept plane. Hd seats in economy may section, so legroom was excellent.

It we as a pleasant flight. Good helpful and happy cabin crew. Food was okay, not to write home about. Drinks good. Entertainment okay.. Seat space good , comfort acceptable

Weren’t even given earphones to use the entertainment system

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

I have paid extra money for my special meal service but I received the the local food. Which is not acceptable.

More entertainment channels and better food, whatever food requirement you select.

Pretty much what you'd expect for an economy flight. The crew were excellent as usual. The food was ok, but nothing special.

They flight was without ait conetion weather was very hot

Worst flight ever.service was extremely poor and food taste was horrible.Served me mashed potatoes and chicken calling it Briyani.

Had to discuss more than 15 min regarding wheelchair they gave only at the start location. No food serv in 1 st flight. Considering flight started at 10:00 pm so had to starve for dinner. Checkin screw was polite. Food in 2 nd and 3 rd flights was not good. It was too cold in the flights. Had to ask for blankets. Missed quality all thru, though the fare was on higher side

The drinks should come before food. Unable to have any fluid unless after food. Thanks

The entertainment on board was really poor. The map doesn’t give enough information and the movies have arabic subtitles, you can’t choose. The stuff wasn’t very friendly and the breakfast really poor. The food must not be spicy! They didn’t have enough drinks.

It was a great experience, can’t wait to do it again soon!!

The boarding at Heathrow is chaotic. That's partly due to the lack of space and seating at gate 8, and a Qatar flight from gate 9 at the same time. That's down to Heathrow rather than Gulf Air. I've had a similar experience here before. Another problem which isn't specific to Gulf Air or Heathrow is announcements, and those for boarding in particular. They are difficult to hear with all the other noise and for me with hearing problems it's even worse. A simple tv screen would help, so long as it's updated of course.

Great! Apart from small sitting in one the flight everything else was good

It was pretty decent mostly cause I have leg room.

Flight was delayed leaving Heathrow by 1 hour. No onboard entertainment and basic food available for purchase.

because of delays of earlier flights, we did not fly BA to Reykjavik. We booked an alternate flight through Businessclass.

It was the old style business class seats which are a long way from the new ones. Also the pork-free breakfast option is always a bit disappointing!

God food! Although some of the snacks were not to my taste. Nice amenities in premium economy made for a comfortable flight. The pilot was able to make up about half the time we were delayed in the ground (we were delayed over an hour before takeoff due to a shortage of tugs) Nice movie selection for entertainment. We were last to board the second leg of our flight due to.complications during transfer from the first flight of our trip, but did manage to board in time. We really enjoyed the video presentation for flight safety. Hilarious gets your attention! Really nice, sufficient accommodations for overhead storage, didn't seem crowded or jam packed. I enjoyed being able to track the flight on my monitor. I was disappointed that there wasn't free WiFi during the flight, I thought that was a complimentary service but you had to pay extra. It felt like we were nickled and dimed on that one.

That airplane is the most uncomfortable I’ve ever flown! Flight 267 LON-PDX Aug 10, 26 The middle armrests didn’t go up all the way. The aisle arm rest didn’t raise at all. The leg room area was compromised by a large metal box on both exterior seats. The headrests didn’t flatten. We got an email apologizing for no WiFi, but on the plane we’re told there would be WiFi. I never got it to connect. Pre-boarding support was great. Boarding was smooth. Crew was great. Food was DELICIOUS. A different plane would have resulted in a much better score.

Lovely attentive staff and even though take off was a tiny bit late, the pilot landed us early in PHX. Smooth easy journey and good touchdown.

My first check in at my origin checked my visa for my international flight but it needed to be checked again. While this is understandable, I had to wait in line for 2 hours to get this second check. More agents are needed to process travel issues in Heathrow. There were times during the 2 hour wait that there was only one person servicing the long line (I don't know where the others went). There were many agents milling about but not working the desk so it seemed as if there were plenty of people at work that day. I attempted to use the automated kiosk but because I had a new visa (not one in my passport). Again, most of this was understandable travel delays but the queue processing time was just horrible.

I travel business class because I like to lie flat on the flight and sleep. I achieved that on this flight, and I really do like BA's new cubicles. As regards the rest of the experience however, I could have been in Premium Economy. The lounge was crowded, and the food/ drink in it was nothing special. The in-flight food was also nothing special, and the in-flight service was pretty perfunctory. Sorry, BA - you need to provide a better service. Cheers
