Airline reviews

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

The friendliness of the attendants, and the quality of the service.

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

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

Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

toilets could be cleaned more frequently, everything else was pretty good.

The seats were more narrow than at other lines. Food was mediocre (economy class)

I was traveling with my 3 minor children, one leg I was seated two aisles behind them. On the longest leg I would have preferred sitting across the aisle from them, not behind. My youngest is 4yos. I understand airplane seating configurations are not the airlines problem but seating the one adult with a reservation apart from the minors was very difficult.

Left hr late & arrived 1hr late luggage was slow to be offloaded! The flight crew & food were good! Movie selection was ok!

The flight was literally cancelled by emirates and you sent me to a scammer website of Underpricer.com for the tickets who still has not provided a refund for one ticket. Kayak has gone seriously downhill. If you are going to redirect people to a site then ensure they are reputable and not untrustworthy scammers. Am never using kayak again after this experience. And update your algorithm or whatever so you don’t send out auto emails checking on flight experience of cancelled flights due a literal WAR!! also I have complained about underpricer and nothing from kayak. So disappointing

Difficult to find some food option for gluten and dairy allergy. May be a fruit salad would be better

What a great trip . From check in to the upgrade we received a big shout out to Cleverson who was able to help us navigate the whole process super patient and was just one of the best customer service experiences we received in a very long time . The amazing staff on the flight who went above and beyond to make sure we were comfortable amazing food and service if you have te opportunity to upgrade it's a must and well worth it.

I love to travel again and again in Emirates. Keep up the good work.

Very good from the beginning to the end. Amazing experience

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

I have a very good experience flighting with emirates. All my expectations were fit well.

Emirates is good airlines. But there plane seats were very small and congested. Need to little good and big seats in economy class.

Food service must be faster and make vegetarian food in good quality

Boarding was chaotic ,wish it was better orgnaised. Seating was comfortable , however food quality left much to be desired. Over all a great experience but with room for imporvement. The Dubai Delhi sector was terrible with poor seat pitch over crowded rack space , crew trying to put even laptop containing bags in to luggage even the waiting area was poorly kept - the dubai - delhi lap was extremly poor flying experience in all respects - the waiting area, the craft the seat pitch & the service quality. It is sad but this will make me look for other options when flying out of Delhi.

We flew business class and it was impressive. So comfortable with delicious food and very attentive and polite staff. Will definitely fly Turkish airlines again.

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Bough tickets with luggage, but made me pay at Airport as well

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

I enjoy flying with Turkish Airlines and such good hospitality among the crew memebers

I did not like the quality of the food and there was no snacks offered between meals.

A little bit more comfort. It’s tight space around the seats. But all else is great and a smooth flight!

Total chaos with baggage check in…..rude staff in Seattle. And faulty seating/entertainment systems. Unable to log in to WiFi desperate being a member. Kept on getting errors. Never again. Definitely not what’s expected from a Star Alliance member airline.

As far as I remember I've selected and payed 65$ for a seat on the aisle. The seat selection got lost and the location was bad.

Mediocre movies Too cold Didn’t have extra blankets Check in was too long (60-70 min coming 3 hours early) Breakfast was terrible Great WiFi however And smooth ride Dinner was decent

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Boston to Doha was great but Doha to Dhaka was the worst experience.

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

You're like a poor man's Emirates Airlines. The Asian vegetarian food was awful. The entertainment selection was very limited and not contemporary at all. The seats were cramped. There was no plug for charging my phone (I refuse to plug into a USB port - A security risk). The plane itself was aged.

Ordinary Indian food... Not great. Limited movie and TV selection

Qatar screwed up by delaying our onward journey for refueling, which resulted in missing our connecting flight to India. the airport qater staff at Doha, herded us like cattle in a very incohesive and uncoordinated way. We were then given 2 options: either catch our original flight the Next day ( After 24.hrs) or catch 2 flights instead , to goto our destination in India. All this, for paying a premium for Qatar.

This flight was packed and undercrewd! Service cart cam by twice on a 14 hour flight

We encountered a glitch when we tried to board the flight because our boarding passes had been printed by Qatar Airways in Jakarta. Those were not recognized by Alaska’s system also we had to step out of line and have new boarding passes printed.
