Just a note -- I have managed on more than one occasion to change flight dates without a fee or an increase in fare. But these were usually weather related. Anyone recall "the storm of the century" back in December 2000? I had a flight out of Boston to Chicago planned that day, and I called to push it ahead one day so I wouldn't risk being stuck in Boston. The airline happily obliged and fulfilled my request without charging anything extra. I also sounded friendly on the phone, if that helped too.[/QUOTE]
I'm only trying to change the time, not date. I'm trying to determine if I could get in trouble by standing by for a later flight that at this time doesn't appear full.
