I flew twice this week on Southwest, was delayed over 2 hours both ways. From Pittsburgh to Chicago it was due to weather but the gate agents, pilot etc were great at updating everyone. Today from Midway to Pittsburgh the plane had come from an international location, kept getting delayed, no information was given until we were delayed for the third time. It was ridiculous, whoever scheduled that plane to fly to Pittsburgh after didn’t consider a lot of things.

Today from Midway to Pittsburgh the plane had come from an international location, kept getting delayed, no information was given until we were delayed for the third time. It was ridiculous, whoever scheduled that plane to fly to Pittsburgh after didn’t consider a lot of things.

Boarding was easy. The seats are small and fairly uncomfortable

I was supposed to be on a later flight. When I showed up at the gate, the woman working there was extremely helpful getting moved up to this earlier flight.

We had a 5 hour delay on the tarmac in Baltimore

Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I rated the experience "mediocre" because of the 2 hour delay in take off. This is the 4th flight from DFW on AA where there was a delay and in one of the instances (after 13 delays), the flight was cancelled. I understand weather but for the March 18th flight, there was no weather issue in Dallas or Detroit. I called Concierge Key and they were wonderful, booking me on a later flight in case my flight was cancelled. I have flown with American for many years and never has there been this consistent pattern of delays. Very disappointing.

They put me on an earlier and I got home sooner

Not good. One of my luggage is missing. And until now they can’t find it

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

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

Really good. I accidentally left my duffel on the plane and the reps were so friendly in retrieving it.

My 9:50AM flight was delayed to 3:40PM "due to incoming aircraft delay". No aircraft is "delayed" that long. Found out once we did board (after several changes in times) that the aircraft had a maintenance issue and we had to wait for another aircraft. Just tell us that. The aircraft we did get was old and the seats need to be updated. I have been traveling for several weeks with AA and you should refresh your entertainment content as frequent flyers have gone through most of your new content. I have Celiac and a shellfish allergy and continue to have struggles with meals on business and first class flights. Please keep this in mind. Sorry - was a long travel day yesterday and a bit cranky this morning with my experience comments. Still an AA fan.

The business steward was absolutely amazing! Smiles and kindness! Wish all AA flights are like this one!

As a first class customer, there was no power the entire flight which limited my ability to work. I find this unacceptable. The first 11 rows on the left side of the plan were out. I was only offered the option to charge my phone which was not the issue because my laptop was out of power. I asked if there was anything that can be done for me, and the answer was, "no". I was not offered any type of compensation for this AA problem which caused me unnecessary stress due to inability to address business issues on an already challenging travel day. Flight attendants tried to reset the power once but that was the extent of their support. Very disappointing for the lack of expected services on a flight. Please contact me with customer focused response to this complaint.

Delay after delay with little communication then AA lost my luggage and at airport would not assist just said scan this QR code to track your luggage and submit a claim. However QR code provided did not work so have to go back to airport
