JAGMAP, could you please clarify whether (a) you were standing by for an earlier or later flight and (b) what was fare basis of your ticket. Thanks.**
2 out of the 3 times was for earlier, and the 3rd time I was ticketed on 51 (LGW/DFW 10:25a dep) and played dumb when I arrived (late) for #79 (2:00p dep). LGW ladies could not have been more accomodating (caveat: I used to fly out of there every 2-3 weeks so they knew me which is why I said it's really up to the agents).
Fare basis was always discounted Y.
