I was refused my seat on American Airlines Flight 1033 departing from Washington Reagan Airport (DCA) going to Dallas Texas (DFW) on 6/24/15 by the airline stewardess who wanted me to sit in the next row because someone was sitting in my seat. I received horrific service by the airline stewardess and had to wait 10 minutes before I could sit in my seat. I wrote a letter to W. Douglas Parker, Chairman and Chief Executive Officer requesting a refund of my ticket and baggage fee in the amount $308.20. I received a letter from another department and was informed that American Airlines did not provide refunds. I also filed a complaint with the Better Business Bureau but American Airlines did not respond. I have been a customer since 2007. What recourse do I have? How do I get a refund for the poor service I received?
