Complaint Review: American Airlines

Due to long wait times through TSA st Phoenix airport I missed original flight. American charged me approx $375 to rebook same flight leaving following day. They confirmed me on a window seat. However, when I checked in for flight I was in middle row. Agents said they could not move me. If I knew it was a middle seat I would have went on different flight or different airline giving the cost to rebook. Nobody is helpful other than just saying nothing they can do. I feel it was false advertisement because I paid for and confirmed a window seat. That didn't happen. In addition, I am a gold member and was told that you don't get upgrades without having upgrade points. What the hell does being a gold member get me if when I want to upgrade I have to purchase points at $40 per point. Phx to NY would take 10 points to upgrade. So I would have to pay $400 extra to get 10 points to upgrade when they say upgrades are free of available. HORRIBLE !!!
