I was flying PIT/MSP/DEN, and just for miles, I SDC'd to PIT/DTW/SLC/DEN - it was on the timetable, so they allowed it! Anyway, on DTW/SLC, I fell asleep in 1A while we were taxiing out. Suddenly, I woke up, and we were pulling back into the gate! They had to deplane a drunk pax (at 8:30 AM, I beleive!), who decided to get up and walk around during taxi. So we arrived in SLC late, and I missed the flight to DEN. Got F on the next flight out, but the moral of the story is, that I got a little greedy for some miles, and I blew a half a day of "stuff" in DEN. (No business, fortunately)
Of course, I'd do it again - - just tellin' a story!
