amazing and great food. everything was smooth from start to finished

love this boutique luxury airline. crew was nice and attentive. Lounge is too small , i think they should have more area for relaxing and lounging not just to sit and eat .. feels like a cafeteria more than a lounge. overall i enjoy it. food on the plane LAX to Teipei should inprove a bit. no flavor and more drinks pls

The overall experience with STARLUX was phenomenal. One of the best highlights for me was the smooth landing in LA(smoothest landing I’ve experienced ever) and the attentiveness of all your staff from check-in to boarding. Also, flight left and landed between airports on time. I highly recommend Starlux to my family and friends and I’m excited to fly with you again.

We are scare because almost missing the fligh from Seattle to San Diego ! Starlux not have enough members for servicing with wheel chairs? We almost left behind , so we must walking !?

FLEW IN BUSINESS CLASS OVER NIGHT FLIGHT AIRLINE BOOKED A PARENT AND ONE YEAR OLD KID PARENT ALLOWED THE KID TO DISTURB EVERYONES SLEEP A terrible flight that was expensive I have 10 grand children I love kids But to be disturbed on a over night flight is in not what I paid for I hold the air line responsible Respectfully, Al Eaddy

I liked everything but I flew business class and StarLux booked another passenger and a one year old , in business class The child cried 80 percent of the flight, the flight was a long 13 hour flight. I’m 75 and I have 10 grand children, I love kids But with that said it still made it not and enjoyable flight. Ask your great flight attendance what they think of the situation, they had to deal with. Let me know what they said Respectfully, Al Eaddy

Everything is smooth. Very good. Except flight arrived SFO 30min late.

more new movies and the blockbuster movies that everyone likes

Great airline. Kind staff, before m, during, and after the flight. They Directed you the whole way. Even when I arrived at my transfer destination, flight attendants guided passengers on which direction to go. I would definitely fly STARLUX again.

Got dinner and breakfast! They had mahjong game in entertainment system. Current movies. Loved the slippers, sleeping mask packet. Great experience for a long flight

The crew need to be more friendly it seem everything such a rush situation during dinner and breakfast. Smiles to the passenger go such a long way just the service from Seattle to Taipei, service from Taipei to Bangkok were great more pleasant the flight attendant from Thailand she was very nice, as far as entertainment were amazing , wiffi connection was incredible great, I will be able to charged my phone from Seattle to Taipei and from taipei to Bangkok I won’t be able to do so flight attendant told me that because I don’t have the original iPhone charger connection has nothing to do what type of charger I have so she said there is nothing she can do about it. Foods : from Seattle to Taipei were ok no flavor , from Taipei to Bangkok I have chicken teriyaki the rice is overcooked all the flavor stuck on the aluminum wraps , breakfast the congee was on point and delicious. Will I recommend anyone to fly with Eva air go for it so you can experience yourself for myself I won’t fly with them again I’m gonna stick with Singapore airlines instead.

Other than spotty internet, great servic, comfortable and smooth flight!

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

My flight was amazing smooth and the attendants were so friendly and nice

Organized boarding process, superb food, lovely crew, even arrived early!

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

What could have been better, was we were delayed from takeoff for two hours. Initially we were informed that we were delayed for refueling. Then we taxied out on the tarmac, then just waited there for a long time, with no explanation of the delay. Were we just waiting on takeoff clearance or was there some other reason for the delay? The pilot, nor none of the crew informed us passengers. That was not good customer service. That needs to be improved, whenever a delay, inform the passengers for the reason.

More seat space More bathrooms Charging outlets Plane was old

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.

Fast and efficient flight. Wifi worked well. Food selection could have been better

Never book through Kayak. They can offload booking to third parties that are completely horrible.

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

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

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

No frills airline with minimal leg room and no entertainment

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

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