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.

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.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Easy peasy. Crew was great. Take-off and landing nice anc chill (good job by the pilot). Thank you UA!

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

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.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

this is starting to seem like an american airlines standard. delayed flights and fake apologies… getting tired of it
