Was not able to buy wifi on the plane given, not available for economy tickets. Was not clear when buying the ticket that this was the case.

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.

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.

Th tray was dirty when pulled it out. Still oily and food stains can clearly see last trip cleaner did not clean well. The toilet sink water did not drain quickly enough.

Passengers were confused and freaking out coz the flight information wasn’t showing on the board that was running with all the departing flights. B9 gate was still showing Cathay Pacific bound for HK 15:50 was on until 22:07. STARLUX staff cameater but didn’t let the passengers go in to pre departure area until 22:45 for the 23:30 boarding time

Greetings when you arrive on the plane and good bye when you leave. Very attentive flight attendants.

Very pleasant overall, although the movie selection could have been better.

Starlux is a great choice for long haul flights. It offers excellent foods and entertainment value. Ground staff are courteous, effective and efficient handing check-ins and understand travelers concerns. Flight attendants are equally great. They're full of positive attitudes and their goal is for traveler's getting destination with comfort and respect. Highly recommended.

Great experience! Food, staff, Entertainment Center, leg room was great!

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.

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

More seat space More bathrooms Charging outlets Plane was old

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.

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.

EVA! What is going on with your food!?!? Pre pandemic I used to go to Taiwan at least twice a year and always flew EVA — the food was consistently tasty for airplane food. Post pandemic, it’s not great at all. Step it up!

seats are pitched well. you don't feel too tight.

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

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.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

The flight who provided services on my row had some not-nice attitude and not smiling at all.

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

The plane was uncomfortable. I paid extra for more legroom but the seat was still uncomfortable. Other seats on the same exact row didn’t have to pay extra but still have extra legroom. I didn’t understand why I needed to pay $170 for. It was Iike China airline just wants to make money off their passengers. It was unfair.

Baggage made it successfully to destination despite short layover. Appreciate that.

Staff were good and nice. There should me 3 meals instead of only 2 and snacks.

Excellent staff made the boarding process fast and easy. Friendly crews on both flights from Saigon to Taipei and Taipei to Los Angeles. Will fly China Airlines again.

The crew was pleasant and polite, but the flight was again delayed for about 30 minutes.

I’ve flown 2 better Asian airlines in the past year.

Seat is too small. Food selection is limited and often ran out of selectable item.

The worst experience ever! Lots of flight delays and rerouting that ended up doubling the total time. . I had to recheck my luggage because I was rerouted to Tokyo and ended up on ANA flight. I missed connecting flight twice because of the delay at Cathy Pacific. Additional stop added, rerouted to a different country for connecting flight and ended up in long waits and delays.

My only suggestion is a way to not be woken up for food. … like maybe something you can place on you if you’d prefer to miss food than be woken up

I wish there were more bathrooms available on these larger carriers.

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

For a transpacific flight, flying economy is awful! The seats are cramped and its meant for petite folks! Good luck if you have long legs. BOARDING - AWFUL, we got to Hong Kong - the gate was listed, but upon arrival, there was a MESS of boarding procedures, they basically DIY'ed how to board but making three lines and putting three ground crew to check for passports in the terminal area. THEN to make it worse, after going through that cattle process, all of a sudden you see people standing and looking confused, apparently we were told to get in line to board, but the AV notification wasnt even working. So people started cramming in line - worse than cattle. One saving point, the flight crew forgot to serve me dinner and after waiting for it, I fell asleep since this was a midnight flight. After letting a crew know that I was forgotten, all of my meals were served first !!! Yay for being in the economy seats! Nothing much to write home about once more!

Cathay Pacific helps me with the planning due to weather delays. Well planed flights.

the seat has a problem. the back had a hole.

The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

I found that it seems that the space for personal bags or luggage is not enough( the cabinets for personal bags or luggage over the seats) .

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .
