Airline reviews

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

Certain flight crew member were rude and short with me when I asked questions.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

The crew very accommodating and food too is good. Keep up the good work

The crews are very efficient. Other airlines should learn from them when it comes to boarding and departing from the airplane. They also display efficiency in serving meals. They don't keep the aisles blocked for hours like some other airlines. The food is poor. Generally the food was unrecognizable and poorly prepared. The only thing that made it better than US flag carriers is that there was a fresh fruit bowl with each meal.

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

Flight Attendants could have been nicer and food portions could be bigger.

Great experience, comfort and food is delicious. Always great service and one time

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

No frills airline with minimal leg room and no entertainment

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

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

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

Food was just okay, need to improve for other menu variations

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

I have difficulties to book wheelchair for my parents returned flight

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

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

All good. Over four hours flight if provided snacks like Qatar Airways would be better

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

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

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.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

It’s a business class ticket but they didn’t give a lounge access

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

excellent, staff and boarding were all seamless and no issues, thank you!
