I've got FF with US, DL, and AW. With US not looking good, DL in question, and AW funding my trips home to PHX and playing in LAS, I need to join a solid FF program. Since I'm about to buy a house, I'd like to start it by using the RE and home loan programs airlines offer. Can anyone advise on which is the best FF program?

While I'm at it, I've just joined, but have been reading these forums for months. You people are fantastic, not to mention fun and interestiong to read!
