This flight was long and I am so thankful I had a seat in the back of the plane. As I usually must get up and stretch every hour . The crew were probably the most friendly I have flown with. Thanks and I will book again with Eva air. Food was ok too.

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

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.

My seat arrangement was good with Eva Air. The toilet sanitary was good ( hand wash, face moist spraying, fresh air spray, hair moisturizer). But the Asian movie selection was not great at all.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

Excess baggage fees are outrageous ($250 per bag). Flight crew and planes are nice.

Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful

Its fantastic!!I like the food the serve in EVA air😊

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

Flight was canceled was only given only a 8 hour lead time. Had to fight to be put on another airline (United Airlines) that was leaving earlier then the one EVA and rescheduled.

Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff

The plane was very clean and the crew was very nice.

The lounge in Japan was busy and smaller. Have great choice of ramen.

Customer service was very good. Food was delicious. Wish the flight was longer.

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I was good seat to keep stretch my legs . but couldn’t keep my bag in my hand . because they told me can’t keep my seat is no holder , because no seat fronts of us. wish I can put my leg on something higher. but instead of that everything goood.

Overall was a good experience. Crew members are nice and helpful.

Good airlines btu ORL airport messed up the return flight for me. Checking out a connecting flight pax is unacceptable.

The pilot was kept warning about the weather terrifying us. The flight attendants were not warm or pleasant.

I always take ANA because of the great service and overall experience.

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

This was an amazing flight. The crew was great. The service was great. The food provided was great.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

American Airlines Business Class does not meet the standard it should when compared with Japan Airlines, Qatar Airways, or Air France. The flight attendants often appear disengaged and fatigued, with forced smiles, noticeable attitude, and occasional rudeness. Food options are subpar, the overall ambiance feels cheap and outdated, and the cabin design reflects a past era rather than current premium expectations. Lastly, the aircraft itself felt old and uncomfortable. Overall, the experience is not competitive with what peer airlines are offering today.

This was serviced by American Airlines. Not as great as Japan Airlines. The LAX domestic airport is not a great airport. We needed to take a shuttle to go to the gate. Mind you, this is just a connection, but we had to go to security again, which is a hassle after a very long flight from Japan. It makes sense, for our checked baggage to be picked up and moved to the other carousel for our final destination, but for us doing the security all over again, pointless. We had our boarding passes already when we were still in Japan, yet we had to start from zero again when we arrived LAX. There should at least be a different line for connecting passengers without going out like it’s our final destination. Next time, I will try to book our flights from any foreign countries non stop to my destination.

I really love their services! From checking-in to deplaning, superb! Highly recommended!

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good

I like the intention and service of the flight crew. Japanese values were observed and appreciated as a customer.

Our flight was delayed by one hour. Luckily, we were still able to make our connection. This flight is really an Alaska Airlines flight and not the same excellent service and comfort as Japan Airlines.

Very comfortab flight. The flight crew and service was terrific. The food was average at best.

First time flying. Very comfortable, plenty of leg room in economy. The food was good, as well as the snacks. Quick flight back from Kansai to HNL.

Excellent service, excellent food and beverage options, plenty of legroom

I wouldn’t know, I tried to contact you days before to reschedule my flight back to Okinawa but you left me on hold for 2 hours. I tried calling multiple times and not once did you pick up. I had to spend 2000 dollars on a one way ticket back to Okinawa because I couldn’t get ahold of you guys to change my flight.
