We left nearly 3 hours late...so that was not a good experience. We boarded and then ended up about 1 hour stuck at the gate. Not a good experience.

We left nearly 3 hours late...so that was not a good experience. We boarded and then ended up about 1 hour stuck at the gate. Not a good experience.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.

Fine except from Chicago to moline three different gate changes and flight times

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

All good. Easy check in and boarding. Lovely flight crew

WiFi broken, very long wait for valet bags, and the typical long wait at O'Hare on a thursday to get clearance to take off and then again long taxi and wait for the gate.

The now boarding notification was not updated in the app until I was actually on the plan. This si a massive fail considering my flight was delayed several times. These types of failures add stress that could be avoided since I no longer feel comfortable leaving the boarding area to get food or visit a lounge. Had I used the notification from the app, I would have missed my flight. The secondly, the process of connecting to wifi on aa flights is clunky and could be streamlined better. the copy and past process feels like MVP, and you are well beyond that stage.

Both flights were late leaving due to repairs/switching gates. The crew and pilots, however, were professional and courteous. Most importantly, we arrived at our destination safely. The seats were comforable. That size should be standard for all economy class. American could improve its boarding process. I am not sure why you need 9 groups for a small regional plane.

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

The delay update was very late. I had a stressful short connection and RAN through Chicago to get to the next flight, only to find the plane wasn't at the gate yet an nobody was boarding. I would not have had to run if the delay was updated earlier.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

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.
