1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Boarded early, left early, arrived 40 mins early! A win win for me!

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

This flight is a quick way to get to Chicago, but a bit expensive.

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.

The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.

I love the e fact that the staff communicated swiftly when my flight was delayed and gate number changed

We had a mechanical delay which made us 90 minutes late (9:30 PM) then land and put into the penalty box because a plane was in our gate? What the hell! We should get priority.Damn American.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

The flight from LA to Chicago was smooth and service was very good overall.

I just for my TSA. So security line is short and upgraded to one group up. I do think the ground crew should learn new way of boarding - the passengers sitting in higher number seat should board first to prevent traffic jam.
