Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Entertainment kept turning itself off. Gave up on watching a movie.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Not United Airlines' fault. It's ORL airport's fault.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

The flight was delayed multiple times. I was autobooted and placed in the center seat in the last row of the plane.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Am still mad at American airlines. You should know it's us travel nurses who are your customers and you treat us like nonsense it's not ok. American airlines took my money, no refund for whatsoever. A trip that was of 466 and I paid 466 and 833 then they chose for me where to sit and refund my seat choices and gave me expensive seats for 79 USD. Kayak doesn't help at all after booking you are on your own. Skyscanner is better

Was a normal flight but it was delayed, and there wasn't an explanation.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.

a321 business class not up to transcontinental & international flight standards

Terrible experience with baggage claim at CLT. Posted as arriving at belt 4 and screen there showed the flight. Waited for over 1.2hrs before someone randomly came by and said the bags for that flight had been dropped at CD1 an unknown time ago. There was no notification in the app, on the screens or by any airport personnel prior to this time. Waiting 1.2 hrs after a 2 hr flight for a bag you paid $40 extra to check is infuriating and disappointing.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

Delay. Flight was delayed in Washington.knew that connection was impossible as not enough time to switch terminals. The steward would not let me stay the night. So forced to Dallas.late night, after 10pm.hotel checkin was one hour. Passengers lined up only one girl to checkin at comfort inn. No food availability at that time. Had to leave early at 6:30 am to catch a flight at 8:45. Stressfull.

I rarely vote ‘Excellent’ but this AA flight out of LGA was amazing. On time departure, early arrival, amazing crew, smooth flight, baggage came out quickly. It was the best airport/ flight experience that anyone could ask for/dream of. Highly recommend. I usually fly Delta but American Airlines really stepped up their game.
