A DL redcoat (Whatever they are called these days) in PIT last week told me that I might be having a hard time upgrading these days because alot of people are buying "A" fares. I always have to go thru ATL and that is where many of the A's originate.
Oh well, I've had it good for the first 6 years, I should be grateful for that. The last 2 years I've been sitting in coach most of the time. My company requires the lowest fare possible, DL wants the highest fare possible, and there is no use of me complaining until one of those 2 factors change.
