The aircraft is fairly new. The screen is big and it's great to enjoy movies on a long haul flight. However, the food quality , and drink and snack selections, have room for improvement.

The aircraft is fairly new. The screen is big and it's great to enjoy movies on a long haul flight. However, the food quality , and drink and snack selections, have room for improvement.

Preboarding food selection is an excellent idea. On the other end I did know the choice. People in my area know the choice. It ends with I got my meal till most of them are half way to finish their meal.

Overall it’s good . However the food quality can be improved .

My luggage was forced open and broke the zipper. I received it in a huge STARLUX plastic bag. Unfortunately, I have a round trip ticket but might be my first and last with this airline

I went to the gate that showed on the flight board but they changed gates at the last minute and I missed my flight. I had to buy new ticket from EVA air to Manila and take 3 hour bus ride back to my home. Will never fly Starlux again!

Starlux was great service and awesome food and drinks👍🏼 will take starlux again for my next vacation👍🏼

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.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

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

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 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.

They need to improve on how the plane lands cause it was not smooth at all.

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.

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.

Coming back to America was a peaceful flight everyone and everything was perfect

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.
