So I'm scheduled to arrive at my destination at 9:30PM. Things have come up and I realize it would be better if I arrived at an earlier time, on the same day. I know there are tickets available. It appears that continental airlines wants $150 as a fee for changing my flight times. Right, this is more than I paid for my ticket!
Can I just show up to the airport early, go on standby for one of the earlier flights, and probably get in?
