Nick,
Thanks. My main freakout was because I'm in the middle of this 11-leg trip. Like I said...I'm more relaxed now that I know what's going on. I'm used to Virgin America and Amtrak where my number has been the same since I started in each program regardless of status, so it made me nervous (e.g. was I going to have to plough through a massive pile of phone call headacheyness because of the switch).
