The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

Terrible because it was cancelled due to volcanic ash clouds in Guatemala while all other airlines kept flying. Had to pay for a hotel to stay overnight in Houston and try to fly next day.

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

The flight changed gates multiple times and flight had to be delayed multiple times

Delayed for mechanical and no updates on what was happening and how long the delay might be.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Mostly good. The WiFi wasn’t working so that was not great.

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.

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.

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

Check in was rough because the check in crew did not know how to manage my international visa documents. Required a long process and 4 people to finally be able to proceed to security. They told us incorrect information several times before acknowledging we did indeed have everything we needed from the start.
