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.

Greetings when you arrive on the plane and good bye when you leave. Very attentive flight attendants.

Serve me a meal, I fell asleep during the flight. So they passed me twice.

Seats are not table comfortable. Crew members are pretty good. Can be much better!!

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!

Excellent service from check in to boarding the crew is so pleasant to asked

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.

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.

Aircraft was late getting to the gate - probably due to weather. We left the gate one hour late and had to wait another hour since we lost our slot in the takeoff queue. Our box was very wet and was falling apart when we got to Clark. It appears that luggage was exposed to weather in TPE while waiting to be loaded. Crew, however, handled the delay well and was able to provide planned service.

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

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.

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

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.

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

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. :)

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!

My ticket did not indication which group I was in for boarding; the gate attended help me

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

Boarding could have been a little bit better but other than that it was a pretty good experience. I think because of the stowaway to Paris France recently they are being extra diligent about boarding passes at the gate. But they boarded the back of the plane first, and that's something I really think needs to start in the USA.

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

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.

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

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.

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

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

The flight was delayed for 30 mins. The overall experience was good.

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

1.It will be better if sandwich is warm. 2.The food is too salty. 3.Breakfast needs some vegetables or fruits.

Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.
