Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

EVA airlines was excellent: on time or early, safe, courteous crew. Highly recommended.

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!

Flight Attendants could have been nicer and food portions could be bigger.

I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. Oh and the seats were more comfortable, had more ability to lean and the headrest was much better for flight sleeping. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea

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

For the price, it was better than other airlines; quality of food and service was very good.

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

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.

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

China Airlines crews are very excellent doing their job. Very friendly and hardworking. I will always choose China Airlines over and over. Thank you all for making my flight comfortable. God bless to all the staff. :)

Staff was so nice and very helpful with directions aswell!

It was our first time flying with China Airlines and had a very nice experience. The airline staff & crews both on the ground and air were very nice. Food on the plane was very good. Will recommend it to family and friends.

Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer

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.

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.

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.

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.

I am Vegetarian also has Gluten free food. However they gave me chicken and fish which is gluten free, but i am a vegetrain and i requested crew Hindu meal vegetarian, they said they will come back. .but they never showed up even i asked 2nd time. They could have compensate. I also request airline industry to have another option Gluten Free for Vegetarin people as well. Because Vegetarin people will have gluen issue...

Just want to do a little more clean up so does not smell like urine.

it was a great experience as far as business class.. but I have had better meals and wine on other airlines.. that said.. the price was a great value for what I got in return.. crew made the difference.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

They ran out of food and were offering random food to passengers.

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

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

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

It’s sad how legacy airlines feel like budget airlines now. Cramped space Non reclining seats No inflight entertainment (need to connect via your own device) Saving grace is the crew. Truly nice and sincere service.

Short flight with limited entertainment wasn't that bad. Staff was friendly and plane was clean. Meal was good.

You have to pay $25 to get access to smoking lounge. One coffee and small bottle of water coupon provided. Max time 2 hrs for two entries total.

Crew excellent calling me by name ! Only downside was no inflight WiFi

Boarding and flying on time is the most important need of passengers they did that

Everything was very good but seats are small for a big man!

Well, I needed to make a change to my flight and I called the airline and they said yes no problem $700 and we can do that and I agreed to it so they canceled my tickets and went to rebook and came back after being on hold for an hour and a half and said I’m sorry, sir. There was an error. It is $2800 Now and I said never mind. I will just use those flights and she proceeded to tell me that they already canceled them because I said I was interested in doing the change. I told her yes for $700. I was fine with doing a change but not $2800 so give me my tickets back and she proceeded to tell me that she could not do that and I had to pay the $2800 to get my tickets back that I already spent $2800 on. So I had to book tickets on another airline to get home And that cost a lot of money too. I’m a little pissed off at Philippine airline right now because of what they did to me and I’m not sure I ever wanna fly with them again. I’ve flown with them plenty in the past, but this just really put a bad taste in my mouth.. Not to mention on my way there leaving Seattle going to Vancouver. I got to the airport three hours in advance and they had booked me through Alaska Airlines to do that little trip. My connecting flight would leave about six hours after I got to Vancouver BC. I stood in Alaska Airlines lying for a little over two hours and then they proceeded to tell me that they couldn’t check me in because I wasn’t there an hour in advance. I kept telling the lady at the beginning of the line that I was afraid they were not gonna let me in because it was taking so long and she said oh don’t worry about it. You’re fine you’ve got time. Well I ended up spending $600 to get to Canada that night just to make my connecting flight because Alaska air wouldn’t do anything and Filipino Air told me it was Alaska air problem but Alaska air said since you booked through Philippine air, we can’t fix it. I had about 50 minutes to make my flight, but they refused to check me in because I wasn’t there an hour in advance yet. I’ve been standing in their line for about two hours and 15 minutes.

reach the standard, crew tried to fix up issues fast.

Theairline, both at the terminal and during the entirety of the flight were kept at uncomfortably cold temps. Maybe between 55 and 60 f. Those who had traveled with the airline before donned puffer jackets, wool hats and pulled blankets from their carry-on bags. The seat back entertainment also failed on my trip, leaving me for 12 hrs. With nothing. Seats offered enough room (barely) for a 6'1" frame, but it was pretty tight But the worst offender was the uncomfortable temp..
