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

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.

The crew were amazing - A great job. They made me feel special and valued.

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

Great flight, great crew, decent food. Premium Economy was very comfortable. I compare this flight to the one we took on BA from DC to London: Like a different airline. The food was atrocious, the crew aloof, and the cabin not as comfortable. Based on that first flight we said we'd avoid BA, but the return trip changed our minds.

delayed more than an hour with very poor boarding and service

A/C temp. was way too cold during the flight.

I didn't like the food, and it wasn't as good as all other business class that I'm using

Flight was extremely delayed and they didn’t feed us for a 4 hour delay

We had a fantastic crew, super friendly and very helpful but the actual boarding part of it was terrible. You actually felt like we were going to a Third World country to be honest all the way up to the airport and the way it was split up going in all different kinds of directions and no one knew what they were supposed to do was extremely stressful

Crew is always very pleasant. I solely fly one world and always have great experience with BA. Thank you!

I'm flying several times per month in business class. You had the worst food by far from any company I have ever flew with. The Spanish wine was great. I purchased Internet, but it didn't work well for most of the flight.

I liked the crew and boarding, short wait between flight was great. My problem was that the WiFi was not accessible through my phone and on the trip from Britain and Larnaca I didn’t have much entertainment. On my way there I felt that the didn’t give up much food for a 6 hour flight….I didn’t eat much in between flights assuming that they will serve something more substantial than what was served so I was really hungry when I was in Cyprus

Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.
