I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

They are very helpful and friendly. The entertainment is great with many choices. They will refill your drink and there is plenty of meal service. I’ll fly with them again when I transit Tokyo.

Boarding was quick and efficient. The food was very good and they had pictures showing you what options there were to avoid misunderstandings.

Boarding was fast and efficient. Not a cramped plane and good comfort. Food was great and attendants were very nice.

Again the ANA flight was canceled. Rebooking with Vietnam air was not good. Vietnam air is sub standard. Will not use a third party booking, like kayak again.

Thanks ANA team, overall I had a good experience flying with ANA. Just one comment, the same food option was served on the flights connecting Singapore -Japan & Japan- Singapore after a week. This drawn disappointment to our expectations to the food and ended up eating the same food one week later on the return trip even though it was a different timing. I believe this could be better managed. Thank you.

Gate agent and flight attendants were efficient, but more stern than warm.

The only issue is that the plane was HOT. This was not the case on my first flight so not sure why, but thankfully I had a portable fan with me. Everything else was great!

This a short easy flight. No food or drink but that was not an issue since we were only in the air for 35 minutes.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

Connection flights should be spaced out farther because too close I missed my connection.

The flight was way too HOT! And the plane did not have any in-flight TV entertainment.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

Simplicity of boarding and corporate interactions were all totally positive and simple, brief, organized and clear. No regrets at all. I will favor flights with Cathay Pacific in the future.

Big selection and great food and beverages in business class with good service. Full recline but less privacy compared with Qatar.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

It was great. All the crew were professional and nice.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

A three (3) hour flight should have meal service in First Class, not just potato chips!

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

Seats suck. Only one drink service in three hours with the flight attendants being more attendant to their phones than the customer. Painful in the extreme.

AA needs to review it's policy whereby it's most tenured staff gets to pick their flights. This tends to place flight attendants with the most jaded customer service attitudes on long haul flights. Whilst I realize this is a generality I have experienced increasing levels of woefully poor customer service. One particular flight attendant on this flight was downright rude to several customers. After serving an awful meal they disappeared to their cots below deck and for the most part did not reappear until 1.5hrs before landing. A very disappointing flight.

Legroom was decent, but the seat comfort was horrible; I believe the seat cushions have lost their cushion. I was uncomfortable and had back pain throughout the nearly five-hour flight. WiFi did not work despite my attempts to get it up and running. This was very frustrating as passengers all around me were streaming football games, movies, and accessing email and text messages. One flight attendant suggested it was my seat, but that makes no sense, given WiFi doesn't work that way. On another note, I rarely have a good experience with aainflight.com.

Id like for them to not have lost my bag. And maybe be a little nicer to me, given the fact they lost my bag.

Seats are uncomfortable and my impressive barely 5’10” frame meant my knees were touching the seat in front of me. My 5’3” sweetheart found the seats equally uncomfortable The crew were transactional. The food edible. The entertainment manageable. The boarding process efficient. The experience okay.

The flight had a 6 hours delay. This should not happen to anyone. Airlines should provide an alternative with no additional costs.

Seat comfort was poor (no lumbar or lower back support).

Pilot navigated severe weather/snow storm with skill. Described his intentions clearly

The American flight was a connecting flight to an international flight. The international flight has a 2 check bag rule. Despite being informed of this, American would only check 1 bag and wanted 100 to check the second (basically a 3rd carry-on) to NYC. Subsequently tsa took a sealed container of maple syrup and a few other things that couldn't be in carry-on plus I had to lug around 3 pieces of luggage for the entire trip. The American reservation was made with the international and American actually checked the one piece the entire way to China. This is one of the reasons that I will avoid American airlines if possible in the future.

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

It was a good flight. Of course it was full, but it went well.
