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.
Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful
The crew very accommodating and food too is good. Keep up the good work
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
EVA airlines was excellent: on time or early, safe, courteous crew. Highly recommended.
Flight Attendants could have been nicer and food portions could be bigger.
Great experience, comfort and food is delicious. Always great service and one time
The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.
Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea
Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.
Delayed. Not a full flight and whole rows left open with the paid seating. Food was ok. My beef meal only had one cube of beef the rest carrot cubes. Entertainment on personal device but didn’t know about it until the flight was almost done.
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.
The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!
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.
It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.
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.
I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.
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.
Crew on this flight dedicate their business class service to their high priority members. They would get priority service even the seats are behind me, and meals priority service and orders. I get the left over choices. I refused to eat because I felt discriminated, never booking this airline.
Leg room wasn't that great. Other than that it was a good flight
Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?
Close to excellent. The only problem is when I try to charge my phone on the USB in front of my seat, the battery level is decreasing rather than increasing. Why?
If my return flight was not so much better, I would have given an excellent review.
Chicken pieces were too big with pasta. Need to be smaller.
Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though
My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.
Great entertainment system, the seat is a bit old style needs refurbishment
I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.
