I think this is rough. There've been numerous occasions over the years when I've switched, NOT because I got to the airport earlier, but because of a mechanical or other delay on my ticketed flight. I wonder if they'd waive it in those circumstances. I'd certainly hate losing that option.</font>
Mechanical problems, and even weather delays, will open doors to many more options than what a voluntary change will allow.
