Airline reviews

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.

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Kayak really screwed up by offloading the booking to a third party. They were completely inept and caused a bunch of toil. I will never use Kayak again.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

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

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

It was ok, but not what it was like 20 years ago

A few more inches of legroom is all i ask

American Airlines was their usual junk service — but at least it got us down to LA. I was more irritated that while they codeshare with Alaska Airlines in Seattle, they could not out our flight on one of these, opting for one of the small SkyWest operated American Eagle flights — and causing a 14 hour layover. Which I accepted due to a $2000 difference in airfare — that said it was irritating for a flight that usually would have cost around $100 extra, if that.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

The crew was very helpful to my family, especially when my daughter became sick during the flight. Will fly with them again.

It was so hot on the plane mixed with being quite turbulent and a rough landing. We all felt very nauseous for hours afterwards. Crew were lovely though.

Two hours late - lack of communication on why or how long.

Old plane nothing worked no charging facilities for phones etc

Everything was perfect. Fast check-in and very roomy seats with plenty of legroom. There was no entertainment but I did not miss it.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

I’ve flown with Qatar multiple times and the service has always been great. Very professional, organized, the food is delicious and plentiful, tons of entertainment.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

Everything from start to end was good and easy plus clean i enjoy my trip in qatar airline

Service and boarding is good in brussels But in Qatar, boarding needs to be improved and waiting in very big queue for boarding. Parents with kids needs to be given some priority also.

Very Old flight. I didn’t expect to see this old flight. The entertainment system was very poor for a 15+ hours flight. The staff was amazing and food could is no bad could be better.

BLR boarding is total pathetic. Should not fly Qatar from Bengaluru. Check in staff is too rude there

I am very disappointed with the way my seat reservation was handled. My husband and I purchased Business Class tickets and also paid extra to reserve our seats. However, our reserved seats were changed without our consent, and we were assigned different seats, separating us. Since we paid specifically for reserved seats, the airline did not provide the service we purchased. I would therefore like to request a full refund of the seat reservation fees. I would appreciate your prompt response and resolution to this matter. Thank you.

I can't believe you have to pay L 3.20 for a Cup of British tea on an airlines with the name British on the plane.

Long haul flight and was really good. Comfortable plane and seats. Really great service all round and always willing to help. Lovely food and drinks (Tanqueray is my favourite Gin). Media was great and helped for the long journey.

Flight was good but couldn’t sleep because bed was so uncomfortable.

This was the return leg of my trip. Tried to do online check in several times, both on BA App and online but it kept saying " it was not possible, check in at the airport". Got to Airport 3 hours before the flight to be told the flight was overbooked and I was on standby because I hadn't checked in online!!! Was told I could go and wait at the gate in case of a no show but would actually be booked on the next flight in 4 hours. At the gate I did actually get in to the original plane... And had 2 empty seats next to me.. So much for overbooked. To add insult to injury, my baggage did not arrive in LHR and was finally delivered over 24 hours later. I don't travel with BA very often.. This experience will make it even less likely, particularly as my wife had exactly the same issue 2 days later.

I couldn't check in over two days online, had to phone to secure a seat and at the airport they put me on standby, at the gate I had to push to get my seat allocated back to me! No catering, a small bottle of water and a biscuit. Yet business had a full meal and drinks service. Very poor.

Spent unnecessary hours on phone calls to resolve small error on one of the passengers name... It was extremely stressful and time consuming... Not great... Also all 4 members of the family: 2 parents/ 2 teenagers were allocated separate seats (even separate floors... Not great...

Absolutely the best airline for service and comfort by far! I only wish I could fly with them domestically!

Comfortable seats, good service overall. The food could’ve been a little bit better. The boarding process was slightly chaotic and in fairness, not all of that is related to the performance of British Airways.

The chairs were a bit tight even though I had extra feet space…2nd plane didn’t have entertainment and even though they said there was free WiFi-I believe the free WiFi wasn’t accessible unless u had some account set up….which I didn’t figure out
