Allow gold card holders (Group 1) to board with their guest like other One World carriers do

Checked baggage process is confusing and time consuming especially when checking oversized bags. Very slow agents didn't help.

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

There were agents in Haneda that assisted us with our short layover, they actually escorted us from plane to gate! Amazing service and kindness maybe eclipsed other minor issues. I had difficulty with on line check-in and because I wasn’t able to do it we had to go to the airport without advance checking. They split my friend and I in seating arrangement twice. Food quality and coordination of entrees and side dishes was a little off. Seat comfort led me to posture where I had to lean backwards a little unnaturally, from an upright position

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Everything was ok!! Just bags came up a little be late.

Tasty snacks. On-time departure and early arrival. Luggage arrived quickly at the carrousel. The only negative was a man behind us that was heavily inebriated. He was served 3 double drinks during the flight. There was no telling how much he had before the flight. He was so out of it that he spilled a drink and broke the heavy liquor glass on the floor. I don't believe he should have been served so much alcohol on a two-hour flight.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

The crew was very kind and always smiling. The seats were great and I was very comfortable during the flight. The only thing I didn't like was that the lavatories got really dirty at some point during the flight. Other than that my experience was great

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

Our seats were all the way in back of the plane,

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.
