I had a deal where the last trip on my hub turning week was a backend DH to the city where I live. I had already spent some of the bank (about $50) on GT for another trip. A training guy called and asked to bump me. For the first time I actually had to think about it as the total loss to me would be about $100 bucks with the bank and per diem loss. Anyway, I knew the guy and said OK . When I checked the jumpseat to ride the same flight home it was full so I had to get Capt's permission from him just to get home. Had there been a change of planes to one with less J/S's I would have ben SOL and SIM (StuckinMemphis). Not sure I would agree to that again..
