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!!

Very pleasant overall, although the movie selection could have been better.

I usually have ear problems when planes land. But the landing was so smooth I didn’t even notice it landing! The service was excellent!

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!

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

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. :)

Most relaxing long distance flight I have been on. And I have flown on many.

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!

I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

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

Ok. Get a different kosher caterer. The food was odd.

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

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.
