Checking in. Flight cancelled after we taxied out to the runway and sat there for 10 minutes or so. Pilot came on and said they had “paperwork issues.” He came on 5 minutes later saying paperwork was resolved but the crew had timed out so we needed to go back to the gate. That took an hour because no gates were available. Once at the gate, the pilots messed up the park job, so they had to call over a tug to push us back a foot or so. That took another 30 minutes. I was so discombobulated fucking around on the app trying to rebook to another flight that I forgot my iPad on the plane. Lulz. After a combination of waiting in line for 1.5 hours and wheeling/dealing on the phone, they rebook us for tomorrow, but send our bags on another flight back home without asking. So we are stuck overnight in a hotel I had to pay for (the only close voucher hotel did not have a room big enough for us) without bags. In short, fuck American. Top to bottom, from the pilots to the gate agent to the baggage office, no one seemed to give a shit. The flight attendant was at least somewhat apologetic. Finally, I may have seen Art Acevedo on the flight. He looked kinda rough. At least we didn’t get raped.
