Airline reviews

I purchased my two tickets on February 2025. Tickets were by each other, aisle and window. However, when we were boarded the assigned seats were one by the window and the other one in the middle of the four seated row. It was a horrible experience and we had to tolerate 17 hours of flight seating by different people. If the airline changes the seat arrangement, it should have the decency to notify the passengers in advance. I have checked my return tickets to Los Angeles, and I have noticed that they are not by each other and I don’t know what to do. I hope someone contacts me and rectify this mistake.

It was all good. Lovely attention by the crew. I lost my glasses but they did everything and eventually found them. They clean the toilets regularly which is a big plus for me.

On schedule, courteous, and efficient. Old aircraft with not so nice lavatories.

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.

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

The awful part was the customs delays at ZRH. The good part is the flight was delayed long enough to accommodate. The flight itself was fairly comfortable.

I’m still in Zurich because my British Airways flight was so delayed, I didn’t make the flight to Los Angeles yesterday.

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.

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.

Really slow transfer after getting off the plane at Manchester, and lost luggage! Take the train, terrible experience on arrival

Because kayak scammed me with false advertisement saying 23kg was included but I ended up having to pay another £200

The flight was canceled and I was directed to Air France two days later than my plan departure day. This involve getting two more days of hotel and also not being able to get a boarding pass until I got to the Istanbul Air France boarding desk. It has been a troubling time.

I didn’t take that flight. My original flight was cancelled from Los Angeles. They rebooked me following day through Montreal My flight was LAX to YUL and YUL GVA

It makes no sense for several types of drinks to already be out of stock in the middle of the flight.

Pleasant and friendly staff. Comfortable aircraft. Speedy boarding. Took off on time. Arrived earlier than scheduled. Overall very enjoyable flight.

I have a walker I need it to get from the plane to customs and baggage claim. It had a huge orange tag on it saying it should be given to me as I got off the plane. It was not and the flight staff didn’t know where it was—both on my flight to London and on the return. In It was very frustrating

They forced me to check my wheel bag because there was a full flight. This was very frustrating. I went out of my way when planning my trip to not have to check any bags. Usually, they ask people if they are willing to check a bag they do not force people. This felt like bad planning on the part of the airline.

Had a plane! Have a plan! Have my luggage! 10 hours of travel turned into 50 hours. Good Lord!

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
