I had to pay FULL economy fare for this emergency flight returning from a funeral in Ohio. So I got to pick my seat at the front of economy, with my carry-on for rapid departure. With my skymiles and AmEx Delta, I had boarding #1. Got on board and a 350 lb lady was NOW attempting to sit next to me on a flight (holding only76 passengers with 35 seats taken (1 in comfort + and 2 in 1st class), trying to sit next to me. NO WAY! I was EMBARRASSED by the senior attendant as I attempted to take a comfort+ seat. The gate attendant, who screwed up initially, came on and authorized my seat at no additional charge. Corporate (and BTW I am a stock holder) heard about this and apologized. Not enough, but maybe okay. I do like Delta, usually, but don't treat me like crap!
