It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

we were delayed going into and out of Newark Airport by 3-4 hours each way. Excuses/reasons given were misleading. Weather was cited at first when there was NO weather issue. Turns out Newark had a shortage of staff and runway construction. United knew this and should have NOT scheduled flights when they know we would be delayed so long. I will avoid United and EWR airport at all cost going forward. Delta never looked so good.

So far so good but food and entertainment are not available for this flight

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

The plane was in Moline all night. Consequently, we assumed an on time departure at 8:15am. Unfortunately, and as is the normal case with United in Moline, we departed 2.5 hours late. When the crew came, it was discovered that there was very little heat in the plane. Seems this should have been checked hours before the crew arrived. Then when we boarded and the plane was to be de-iced, the United de-icing truck was not working! We awaited the American Airlines truck. All of this caused us to miss our connection in Chicago. My suggestion is never take United Airlines flight from Moline. We have been disappointed 80% of the time and have vowed to not take United again from Moline.

Most disapointing experience. We were rerouted to Toronto, after a 7 hours flight , where we sat on the tarmac for a little over 4 hours, in a full airplain with no air. We were given a tiny cup of water twice during that wait. After the long wait we taxi out of toronto to wait another 30 min. Many people missed their conections including my kids and I. We were promised a hotel room in Montreal on the aircraft and at the exit of the aircraft, then directed to a desk after custom where me and my two kids were told that we do not get a room for the night and that we were on our own, after a back and fourth and stating what was told to us, the agent at the counter says that we are right and that we should have a room. I ask the lady if she could look into a different flight for us for the next day as I was with two you g kids and wanted them to get some rest. The gentlemen next to her jumps in and said there wss nothing without even (pretending) looking at their system, I insist and say that they could look for the kids. They seemed to have trouble with our reservation so they gave up. I told them that I needed to talk to a manager, they said there were no managers and that no one can do anything, to which I responded that there must be someone that could do something and that it does not make sense for them to repeat the same think as we are not undestanding each other. She threatns to call security and says I am rude. I say I will go, just give me the vouchers and ger response is “ not giving you the vouchers because you are rude”. I was not rude. It is normal to want to talk to a manager. I even said that the people at the counter were not resoonsible for the long journey and that there was nothing they could have done. But to threten and himiliate someone just because they ask for someone else to talk to ? I understand they are overwhelmed, but you know the quality and calibre of a company in the bad times not the smooth ones. I ended up leaving and paying for my own room and board.

They needed people to check a bag, they did check my bag and I had to wait 10 minutes after the flight to get it it wasn’t too bad

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

The flight was 2 hour delayed, otherwise everything was excellent. The delay was due to the hourly limit requirement so given that as a reason, I'm happy with the flight!

The pilots are always hauling in the sky. No issues with boarding only problem was layover was shortened too much by weather but luckily the next flight was still boarding and did not missit

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

On time arrivals and departures. Gate boarding notices could be better if displayed on monitor.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

Checking in at the counter was very disappointing. The lady had a very bad attitude and smart at me. She had no smile, did not greet me by name, or acknowledge me as a valued customer. Poor reflection of the airline.

The service could have been better and the food was bad
