Loved the boarding process. All airlines should board from the back to the front. Very efficient. Food was excellent, crew were great, seats were spacious and comfortable and the entertainment screen was the best I have seen.

Flight cancelled due to inclement weather yet rival airline EVA Air with the same route departed 2 hours later and landed safely while our flight was cancelled and rescheduled for 36 hours later.

The staff in air and on land went above and beyond! I would definately recommend and we will fly Starlux again!

I need Starlux to respond to my complaint and issues for my flight.

Someon vomit during boarding. My seat was next to the vomit. I asked crew member to switch seat, but they said it was a full flight. I had my baby with me. My baby got sick after the flight. He was in the hospital for 2 days.

The airplane so clean and they have a nice crew

it they come out with resent movie and good food

The crew could have been kinder and less pushy. The premium economy seats don't have enough cushion. The seats are to hard and the flight became painful and uncomfortable after an hour of flying.

Aircraft is new and toilets are spacious, but toilets are quite filthy. They should clean more often. They have a long list of drink offer but are actually not available during meal. They said they’ll come back with them and you don’t get them until after dinner which means you eat your meals without any drinks if you were to get something that they don’t have on the cart. They are strict about removing headphones during take off and landing which is new to us since the movies did not get turned off. Instead, we we’re forced to watch their commercials during that time. We probably would fly with them again but not with the cost we spent. For the record, I work in tourism and travel a lot for inspections.

Our transit in Taipei was disappointing. The ground crew could not tell us where the lounge was located, so we wasted 15 minutes trying to find it. The airline has a great review, but our experience says otherwise.

Seats. there's no way to go to the washroom when you’re seated in the middle without bothering the person beside you.

It was very long way flight but its good I like the food they serve in EVA air its really good!

Although the flight was slightly delayed, it was well communicated with the passengers. The staff are all nice and accommodating, the pilot are very good. I didn’t realize that the plane was on the ground already. It landed smoothly. I’ll for surely recommend EVA Air to my friends.

My ticket was with EVA Airlines, but Asiana Airlines was the ground crew for EVA Airlines. Me and my family member finally received our boarding passes after waiting to check-in, which took over 30 minutes. I had never done a tax refund before, so I crossed immigration without going to customs to receive a stamp for my tax refund. When I went to the tax kiosk on the other side of the immigration gate, NICE Tax Refund asked me to talk to an airline staff member. I could not find any airline staff member, so I went to the Information Desk. The woman at the Information Desk told me and showed me a sign that read that I needed an airline staff member to accompany me to cross immigration again. The woman at the Information Desk phoned EVA Airlines and Asiana Airlines. I also phoned, but there was no answer. There was still 80 minutes before my flight would leave. I waited for 45 minutes. I spoke to Information, not one time, but two times and the woman assured me that this situation happens often and it is nothing to worry about as the airport is small and once the airline staff arrives, it would only take 10 minutes to go get the stamp and I would be able to make my flight. Then, 35 minutes before my flight was scheduled to leave an Asiana Airline employee, accompanied by the woman from the Information Desk came. Asiana asked me to confirm whether I wanted the customs declaration stamp. I answered yes. Then, she said she would like to state that I should take full responsibility if I could not make my flight. She asked whether I wanted her to proceed to contact a staff member to take me to get the stamp. This was very suspicious as there was still 35 minutes remaining until the flight took off. I directly said to her that the question was very strange, but as there was enough time remaining, I did not see a problem and wanted a staff member to accompany me to get the stamp. She went away and came back 5 minutes later and asked me whether I had the item I wanted to declare on me and how many people were traveling with me. I told her I had the item with me and I was here with a family member. She then went away again for another 5 minutes. When she came back she asked whether all members would not be traveling as well. I stated that I am not sure why me or my family member should not board the airplane. At this point, it became apparent that she was not helpful, so I tried to talk to other airline staff. I also talked to a woman wearing a reflective safety vest, who was organizing the gate bollards for boarding and she said she would take me after boarding. When I asked, how I would board the plane, she then said, you will not be able to. I then talked to a man, who spoke Mandarin and appeared to work for EVA Airlines. He told me it was my fault and not his and tried to re-direct me to another person. He was not busy at all. At this point, it became apparent that, Asiana Airlines and EVA Airlines, were more interested in delaying and preventing me from boarding the airplane. In the time the airline staff wasted arguing with me, they could have just brought me to receive the stamp. It seemed apparent that I was not going to receive the stamp or the tax refund, so I stepped into the boarding queue line. Again, the airline staff, the woman in the reflective safety vest asked me to confirm that I would not be getting on the airplane. I was already boarding! There was written signage of the procedure at your airport’s Information Desk. Then, I was passed to multiple airline staff that were not willing to assist accordingly. There was no one at the customs declaration counter and no one else from the airport to assist me. EVA and Asiana Airlines both avoided responsibility and delayed the procedure. They were rude and indirect about the situation with every attempt to prevent me from boarding. Deterring foreigners to depart from a foreign country over tax refund issues is unlawful.

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

Service in BKK was very good at answering our question about our canceled flight from Taipei to San Francisco. Did like the lead time about the canceled flight from Taipei to San Francisco and was not given the best options.

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.

The EVA air staff at Narita did a terrible job with signage and communication. Despite getting to the airport hours before, they had me queue in line and did not communicate that passengers for Kaohsiung need to step out of line to go to a different line. If you put the flight number at the front of the line, people will think that’s their line. If your staff walk silently down the line with a sign of the flight number, how are we supposed to know you want us to follow unless you speak or write that? I even asked the staff with this sign when we could check our bags and they assumed I was on the later flight to Taipei. Later, Wl only 30 minutes remaining I called for help, and the staff looked at me like I was in the wrong. I had to rush through security and customs and had no time to eat or buy a gift. I’m deeply disappointed in the way they handled it, and it caused unnecessary stress on my vacation.

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.

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!

The flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

I love my Delta crew, they were so welcoming and helpful.

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.

Overall was a lovely experience. The crew were kind and courteous throughout the entire flight.

Sat next to a woman who had her period. Blood was on her seat and on the arm rest between us. I ended up having period blood on my jacket and shoes. Very gross!

Better organization of boarding procedures. Terrible leadership guiding people to gates.

I did not like how the plane landed. It was not smooth.

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.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Old plane and old configuration/seats but still comfortable for a morning flight

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!
