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 !?

We are on economy premium but they put us in economy seating? Asking why the fligh supports said : If you not happy you can claim for refund?

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.

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.

Service was great didn't leave on time was not good

We travelled with a toddler and was allowed extra time to board first which was very helpful!

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

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.

We boarded late and it snowballed from there. Had to wait behind 6 other flights to take off before us. Then, arriving late to our destination, we had to circle in the air for 20 minutes. If that's not enough, the seats are very cramped on their iteration if the A321neo. I'm 6"3' tall and my knees were pressed against the seat in front of me. These are not the slimline seats that offer less cushion with more leg room. I had no room to move my legs. Since I am an adult male, I also had no shoulder room. I sat on an aisle seat to have some space to lean my should out. But the walkway seemed to be more narrow than I am used to see. I felt bad for the middle passenger because there was just no where for me to put my shoulders except into the middle seat person. I don't plan to fly in this airline again in this configuration. Pack everyone in and lose my business.

We really enjoyed our flight to Seattle. The food was great and service was attentive.

Everything was fine except the seats were quite compressed and hard for the 12 hour flight

The crew are amazing. Very professional, polite, kind, and accommodating.

The crew was very professional and friendly. Although there was a water leak from panel above, the crew was trying to mitigate the consequence. We are happy with its service and the value offered. We will definitely take China Airlines again.

Well, we upgraded and on a 14 hour flight not sure how we would tolerate it otherwise. The upgrades are ridiculously expensive and even with empty seats even in first class it was difficult to upgrade. Probably won’t fly China Air again due to this. The attendants tho were much better than the airlines in the states and there attentiveness and care for your comfort far exceeds other airlines in the states.

Flight attendants. Food, entertainment and most of all, be on time.

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.

We are glad to have used China Airlines for our trip. Continue the good service! Thank you!

Smooth sailing trip, pilots are good. Less amount of food offered but the quality is okey.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak uses scammer sites to steal money from their victims.

Customer service and attention to details. The food was good.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

I am thankful that I was able to fly using Asiana

Better screens, it would have been nice to have more comfortable seats.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

It was amazing with great service. But the seating could have been better if there was ample arm rest areas

Flight attendants did very well, they were all friendly and very helpful .

Everything is ok except the manner of transporting the people that includes me on a wheelchair. That was my first time cuz I was suffering from “sciatica “ and couldn’t walk well. Upon arrival at LAX it took me almost 3 hrs to get out of the airport bcuz of these wheelchairs procedures. If only I can manage to walk I should have done so OMG. Other than that so far everything is ok. THANK YOU.

Check in process was excellent. Lounge needs improvement. Food not palatable and no good choices.

Absolutely terrible. I will never fly that airline again. The problem was with the constant emails changing my seats, arrival/ departure times and the aircraft. The staff at the airports and onboard were great. Between making the appointment in May 2025 and my actual trip I had over 50 emails announcing changes. I was traveling with 3 other couples and they experienced the same thing.

Apart from a departure gate change, a good experience with professional, friendly staff.

Excellent service from check in/ bag drop counter staff to flight attendants. Food was great. Seats are nice. Excellent airline.

My luggages were lost and the service attendant was extremely unprofessional. Despite presenting my luggage claim slips, the attendant stated she had “no record” of my bags and made no meaningful effort to assist. When I explained that the luggage contained our family’s complete scuba diving equipment, her response was dismissive, stating that she “didn’t care.” While lost luggage is frustrating on its own, the lack of professionalism and lack of empathy significantly worsened the situation.

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

Flight was good took off on time arrived early. Crew was awesome and did a great job. Very helpful and courteous. Bags arrived super fast with no hassles. Great flight!!!!!!
