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.

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.

Unable to set seat assignment. Got a call from presumably “China airlines representative” but was asking for an exorbitant amount for the seat assignment. Was traveling as a family end up being assigned to different seats as a result. Will never use underpricer again.

Not many selections for entertainment. Bulk head seats are no longer available with out fee at the counter. That’s pretty lame.

I would have liked to know how to order a special meal (for medical purposes) before the flight.

Staff very friendly and helpful Everything was clean and most important on time Unfortunately let down by the quality of the food Would be very happy to use them again

The flight who provided services on my row had some not-nice attitude and not smiling at all.

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.

Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

The plane was uncomfortable. I paid extra for more legroom but the seat was still uncomfortable. Other seats on the same exact row didn’t have to pay extra but still have extra legroom. I didn’t understand why I needed to pay $170 for. It was Iike China airline just wants to make money off their passengers. It was unfair.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

Not pleasant. We arrived several hours late and my friend and driver were waiting for me a long time at Tucson airport. At first we had to divert to phoenix due to shitty weather. Well, i guess I can’t fault anyone for that. But then when they refueled , they overfueled and we had to wait even longer for the plane to burn off excess fuel. So someone really screwed up there and should get fired. Human error is really inexcusable.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

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.

Everything was great except for the seat. The backrest would not stay in the upright position.

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!!!!

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

My encounter with the entertainment services provided on board was moderate; the functionality of the Wi-Fi connection was either sluggish or nonoperational, while the display screens were antiquated and suffered from poor visibility. On the positive side, the cabin exuded a sense of expansiveness, and the crew exhibited amiable and accommodating behavior throughout the journey.

Everything was great except for some reason crew and ground crew could not figure out how to deal with an electric wheelchair and it delayed us 20-30mins. Was pretty frustrating for passengers and the captain.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

Traveling with JetBlue from NYC was convenient as accessing JFK airport was straightforward via the LIRR to the AirTrain. Maneuvering through the terminal was hassle-free, which was a pleasant start to the journey. However, the flight experience itself left much to be desired. The seating arrangement was notably uncomfortable; despite securing a window seat, space felt cramped. This was exacerbated by the middle seat passenger encroaching on my area, which made the flight less enjoyable. Additionally, while the in-flight entertainment system initially seemed like a reprieve, the sound outlet on my seat was inoperable. This issue turned what could have been a manageable three-hour flight into a rather tedious ordeal, as I was unable to use the entertainment system effectively. While JetBlue provided a smooth process in terms of airport logistics, the on-board experience highlighted areas in need of improvement, particularly in terms of comfort and entertainment system maintenance.

The flight crew that we had in our section may have been tired or something. I asked the flight attendant about my son’s screen not working and she spoke down to me like I was stupid. He still had no working screen throughout his flight. The other members had no personality and seemed like they were annoyed when you asked them for something. Definitely took a hit for simple things on my JB experience.

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

They delayed our flight by 45 minutes and then re-updated the departure time back to normal schedule with no notification, email, or app update causing probably 40 people to miss the flight as they left without us.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

Luggage management is poor, my missing luggage is still lingering.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

Very poor the plane itself was really old, slight smell that couldn’t be named. I didn’t even get a boarding pass UNTIL AFTER clearing security! Even then, they said when I get to my connected flight I’ll get my 2nd boarding pass there! A bit ridiculous!

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

Delay 14 hours! Missed all connections and had to fly different airline the next day.

Excellent. Attendants served preflight drinks and were courteous and nice.

It was perfect in almost all ways. In fact it arrived early in both legs of my flight. The entertainment was marginal, but that was due mostly to the length of the flight. I love American!

American dropped the ball on this flight. It was canceled after waiting on the tarmac for 6 hours. American airline was so greedy that they open the door after close, delayed our flight then caused the pilot to over 14 hours limit if they were to fly to Phoenix. So more delays and finally flight canceled. Horrible experience with American Airline in Philadelphia.

They took away my first class ticket for my plane ride from Ickx to Tucson because they’re plane was late getting there. They offered me nothing in return

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Flight attendant was incredible. Very efficient, friendly and pleasant. Patricia was one of the best I have ever seen. Please give her a big raise!

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.
