Their announcement was not quite clear in Chinese. The rest is pretty good.

Their announcement was not quite clear in Chinese. The rest is pretty good.

The hygiene of the bathrooms were terrible. Urine smells leaked out into the cabin and the seats were really tight, even for a petite woman like myself. Flight attendants did not go through the cabin enough to offer refreshments.

Fast and efficient boarding. Flight was on time. Service was very good for our long flight. First time flying with this airline and I would highly recommend.

Eva Air's Business Class is pretty decent. With the given price, I think that the food can be better.

Pleasant, comfortable, and entertaining. All told, ZERO issues with it. And sadly, so far the flight was WAY more comfortable than the hellhole that is "Lambug Beach Resort" at Badian Beach!

It was a pleasant fly with Eva Air from NYC to Taipei. The crew were friendly and the food was exceeded my expectation.

Eva air is a good airline. The seats on the way to Taipei could have certainly been more comfortable, but all in all it was a pretty good experience.

Overall the flight was what might be expected for a long haul flight to Asia in economy class. The cabin crew was attentive and the food was good. Boarding was fairly fast and easy. The one thing I found frustrating was the EVA app. It is terrible. Trying to do anything on it was almost impossible.

EVA would not help with ticket issue since they were purchased through a travel agency. Even though it was EVA ticket stock. Travel agency Budget Air didn't reissue ticket after airline change which I didn’t learn until trying to checkin on Christmas Day and there was no contact number for the agency to help. I will never use Budget Air to purchase flight again and disappointed in EVA’s refusal to help. Thankfully just under 12 hrs before departure someone from the agency was available to reissue tickets. I was starting to think we would not be flying and the stress trying to resolve was completely unacceptable.

seamless check in/ friendly staff, food is good, always love flying Eva Air

Very good , the weather was terrible, but i admired the professionality and politeness and care from the crew, and the excellent contition of the plane

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

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

It was a 2 hour flight to Taiwan. Lunch was served. China Airlines goes above and beyond for their passengers.

They were helpful, considerate with asking us for standby preboarding with our infant, gave us toys and excellent service onboard. They were always on time, even early boarding once! All our luggage arrived intact, and they even brought our baby car seat to oversized for us. We love China Airlines!

Staff is friendly, great variety of entertainment, check in a little messy but due to people not listening. Overall a pleasant experience. Would use again in the future.

It felt like a new plane. Decent leg room in economy, food was fine, and the plane didn’t feel super dry and uncomfortable.

Free Wi-Fi could have been better in the Airport.

Ask flight attendant for water during flight and she was a little rude get the water.

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

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

On time take off…US cabins look tired and need of refresh!

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Check-in was tedious. They could just have used the electronic boarding passes and counter checked the passengers’ names in their manifest. What’s the use of the early checkin if we still have to queue at the only 1 functioning checkin counter!

So far pal express is much better than Cebu pacific in terms of customers service and in flight crew. And on time departure and arrival . Especially if you're taking airbus 320 plane . But the small aircraft like bombardier . It usually delayed .

Checking in was okay but boarding a little bit slow

Everything could better always late always rescheduled flight is worse and costs me a hotel room! The dirtiest planes I’ve ever flown on slowest to board . Just awful will never fly again with them

Not leave 12 hours late. This airline is horrible always late does not refund upgrades for cancelled flights inept counter staff.. needs to be shutdown

My biggest concern was with all the schedule changes. Both inbound and outbound flights times were changed, including a time change less than two days before the scheduled departure.

Flight delayed by hour for departure. No real announcements or updates until told to start boarding

The economy class sitting/chairs is tight not spacious enough to sit comfortably but for other matters everything is perfect 👍☺️

Every thing was good except our baggage that wasn’t here when we arrived, we understood the cause but hopefully we will get it soon as possible

Flight was delayed. What’s better is if the flight stay on time.
