What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

The entertainment wasn’t playing in the app or online.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

On time departure & early arrival. Made a long day much better.

Like all planes recently, entertainment is achieved by giving the patron free WiFi and letting them stream shows via the screen on a phone or tablet.

Crew and agents misguiding on tight connections, and lack of connecting crew looking for inbound planes. A very avoidable missed connection as a result.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

American Airlines changed are gate no fewer than four times. Walking back and forth from one concourse to another was exhausting, especially after all the flight delays.

Hydraulic leak caused the flight to be cancelled. Auto system scheduled us on a 3 am flight. Wevhsedvrebook on the app and hit schedules later in the afternoon. Our luggage per gate and ticket agent would be rescanned and put in our new flight. Did not happen. Our luggage stayed in hsv. Baggage claim in wash dc unable to help. We filed a claim. Several emails about our luggage were in conflict with one another. Called as baggage and was on hold 30 minutes. Oscar said one of 2 was out fir delivery then cancelled. About 45 minutes later both pieces were delivered. Their system is suspect

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

It was great. Smooth flight, comfortable, left on time and landed on time.

Horrible experience upon landing. Probably more due to DCA utter incompetence than AA.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)
