There was a big delay and I missed my connection flight

There was a big delay and I missed my connection flight

I had problems issuing the online boarding pass for this connecting flight. I had two booking codes (Kayak and American Airlines) and neither of them worked; I didn't receive a booking code from Gol. I had to call the airline (Gol), which gave me a third booking code that allowed me to issue the boarding pass. Even so, the QR code on this boarding pass didn't work at any point between entering the airport and actually boarding, which required document checks by airport and airline staff.

For an international flight the seats were smaller than most flight I have been on in economy. I don’t know the size of the seats or perhaps it was the size of the seat dividers that made the seats feel smaller and little amount of space to even turn your body if you needed to

Appreciate having multiple food options for allergies. Nice to have an extra seat between us for comfort.

Flight was delayed 17 hours due to aircraft issues. American did provide hotel, transportation and meals, 3 hours past boarding time, but it took us another hour to get the vouchers.

My flight was delayed for 17hs because the pilot forgot his passport!!! What a joke. AA used to be a great airline, now I have to think twice before flying with them again.

Food was terrible, all served at once, poor quality . Wine and bread offered only once.

Flight cancelled. Added a day and a half to my travel. American Airlines DID put me in a hotel for two nights, but have not given any money back for any of this! I spent money on an apartment at my destination that I basically wasted because I could not arrive.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

When the first leg of my American Airlines flight from Atlanta to Miami to Sao Paulo to Brasilia was cancelled because of a tropical storm in Miami, American Airlines put me on Delta Atlanta to Sao Paulo where I caught my original Sao Paulo to Brasilia flight. American Airlines could have put me on a flight the next day or even 2 or 3 days later. But, the agent went above and beyond and made sure I got to Brasilia on time.
