US Air - stop the sales

I am a united flyer for my shame so when i cannot get a decent price on UA I fly US Air. Now every time i fly they try and sell me a credit card. I have tried to ignore it and be tolerant but i just cannot handle it anymore. The best thing was when i was walking off a flight and the attendant/sales associate was saying "I got 5, can you believe it, dinner on me". I in no way am criticizing the people doing the selling, i am just a bit sick of paying to be in a seat so that they can pitch to me...i must be getting old and grumpy.
