Counter personnel were friendly and professional. Assured me my bag would reach Bangkok without having to get it and recheck it for my international flight from Seattle. Also printed out all of my boarding passes for my trip.

Counter personnel were friendly and professional. Assured me my bag would reach Bangkok without having to get it and recheck it for my international flight from Seattle. Also printed out all of my boarding passes for my trip.

The food was amazing good especially for evonoply. The seats were comfy more then usually..crew was very nice and helpful.

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 !?

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

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.

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.

This Airline is really good! Better than Eva air for sure and more luxury. I really liked all the small details and amenities plus it really is free alcohol!

Efficient boarding, on time departure. Cabin crew all nice looking and well dressed, helpful. Plane interior looked modern and new, fresh condition.

My husband and I like this airlines , lt looks new ,clean & good service. Then we will fly with STARLUX again. And I love their time , it is perfect for my family. See you soon.

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 flight attendants should be nicer, on my first flight I told them I’d prefer a veggie meal sometimes and then she began to lecture me about it, it was a late flight and I wanted an easy digestion meal so that I can sleep quickly. The meals were abit odd, breakfast on my last flight had eggs, oatmeal and fish, did not taste good at all, strange combination. The economy seats are very tight and crowded, not comfortable at all. Overall for the price I paid I thought I was going to get more.

Clean plane, friendly crew, mostly on-time departure. Negativo since there were no snacks offered. Cold drinks only was fine due to turbulence, but nothing to eat? Really?

Except for crying babies all was ok although the movie selection wasn't the best.

Poor food on board, but seats are too small and uncomfortable

1. The entrance to boarding gate G5 (which is at a lower level) is from the walkway (which is at the upper level). That entrance was locked and there was no place for hundreds of people to sit at the upper level, for a long time as the flight was 45 minutes late. 2. The choice of movies on board was extermely limited and poor. 3. The staff was unhelpful and faked politeness.

They didn’t have ice for the drinks and only gave you half a cup of your beverage. Did not have enough water. I got dehydrated

Fast boarding process. Flight was expected for a long haul economy flight

The flight went well. Everything good. Boarding. Meal service. Snack (crackers) & Drinks. Entertainment was good as I watch 4 movies. The need to have milk for hot black tea though as coffee creamer just never makes tea taste nice.

Everything was fantastic! The crew really went above and beyond to make it a great flight. I felt cared for with EVA.

When requesting water, make sure, as a passenger, you specify cold or ice added to your cup

This was the first time traveling with China Airlines. The Crew, were all professional and bilingual. The aircraft was clean and comfortable. I upgraded to even more space; that process was simple and not super expensive. The meals served were adequate and tasty, and the choices were suitable. After experiencing long flights and being a passenger with China Airlines, I must say I will travel with them again Sincearly Anthony

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

Been flying with China Airline over years many times. Good experience with them, no issues.

Airline itself is great. While food was being taken off of my tray my beer spilled which was a total accident and I wasn’t upset about that, what was frustrating was I had to ask for towels to clean up and wipe my leg. It would have been left as is if I hadn’t.

Bars and restaurants in Taipei close early. The lounge isn’t very good, but better than the public areas.

My flight to Los Angeles was canceled Had to book another flight and you charged me extra $500 Very bad experience

3 of the 4 flights had delays despite the weather being fine, but still managed to make all connections

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

The plane was an older model and the entertainment was hard to enjoy on those small screens. I struggled to see clear anything I wanted to watch. The seats where a bit uncomfortable but for a 3 hours flight it was pretty ok. The rest of services were excellent. Highly recommend China Airlines to others.

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

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

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.

Staff always with a smile and very helpful with my mom who has mobility issues.

Great service. They could offer vegetarian food and do more to reduce waste.

Very comfortable seats, delicious meals, and friendly and helpful staff

Staff was excellent. Food could use more variety. -More vegetable options. Menu didn't have juice or soda listed. -The croissants were outstanding!

Asian Vegitarian food was test less No Salt or pepper served Need to improve with Chef who can caters for Peaple from India I am sure Chef knows different varieties of food Indian People like

Airfare was ok . Food not good , seat ok but not comfortable. Lay over too long , crew was ok Overall just ok

2 things that really tanked our experience with this trip with Asiana Airline (which used to be among my favorite airlines): 1) The "random" security screening at the boarding gate is crazily thorough (which is completely redundant to the security screening before we went through the security checkpoint before getting into the gate area), and the water was acquired inside of the gate area (from a lounge operated by the Inchon airport). We were asked to take out *EVERY* single items from the carry-on luggage and open up every comtainers / bags / packages to inspect. To add to it, there were two inspection workers there (one seemed to be a trainee and the other seemed to be a trainer), and the trainer worker held a very unfriendly / arrogant attitude towards us. As the youngest member (a minor) of my family was being "screened", the rest of my family wanted to make sure that no inappropriate actions would happen to her. That trainer worker yelled at us and attempted to use rude body language (waving her hands) and facial expression to ask us to stay away. 2) The luggage handling at the destination was really *REALLY* bad. Among my 25+ years of travel experiences, I'm going to have to say that this was the worst luggage experience where we didn't lose our luggage. Our flight was scheduled to land 12:45pm, and landed around 1pm. 15mins delay in landing is absolutely normal. Deplane process took a bit longer than usual flight (we waited for around 20mins, after arriving at the gate, before people were able to actually leave the plane). However, the luggage took another *2 HOURS* to arrive at the baggage claim carousel. This is insane. What's worse is, due to the delay in luggage, the flurry of passengers from our flight collided with 3 other incoming flights. The US border / custom line was like the longest Disneyland attraction line winding through the entire arrival hall and around all the baggage claim carousels (like at least a thousand people). I've never seen anything like that at SeaTec airport (US border control), period. The luggage claim experience really tanked our trust and overall impression for Asiana Airline's Seattle airport ground operational effectiveness and efficiency. This has to change in order for them to remain relevant / in-business with increased competitions from Korean Air and other Asia-based airlines.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

The flight attendant on Korean airline was a super nice. it’s one of the best over-sea airline I flew so far.
