Hi all!
In response to jaguar (& this might affect things a bit):
I've got around 15K on TWA, 5K on CO, 5K on DE, 2K on USAir, & about 1K on UA.
Thanks all for the HHonors link -- I'll look into that. I know about all the credit/LD offers (been lurking here for 3-4 months now), but since I can't afford the annual fees for all those credit cards I've got the Starwood AmEx Optima.
Thanks again to all!
