Many years ago I was on a trip that on Dec 24th was supposed to end with IND - AUS, dh home. We were revised in IND to go IND- PIA- IND, dh home. Naturally we all deviated in IND because it was Christmas eve and got out of there on any flight possible. When we left ops in IND the pairing showed a revised dh of $2000. After I eventually made it home, the trip was later revised to another dh with only a $600 bank.

So it may not be the one that you thought that you flew.
