Thanks, everyone, for posting this info. I, too, didn't realize the differences in the calling plans/rates. I hated MCI so much when I was with them, no amount of miles would make me switch back (well, maybe 50,000 miles), so I've just stuck with AT&T. I recently attached my AT&T account to earn Hilton Honors points on "qualifying long distance rates". They promised me the rates wouldn't be any more than I'm paying now. Great info on these websites. It's also good to know that there are no hidden charges on many of these 10-10 numbers.
