IFly,
Looks like you'll probably be in the Rj with your experience, so I don't really know what to expect there, except reserve for a longer time than if you get the emb. Most newhire rj dudes are going to slc as people are transfering to DEN, PSP, and SBA like crazy. We have no formal commuting policy here, working on it though, but most people who commute don't have too much problems getting to SLC. Schedules for reserve are 20 duty days per month, so you'll get 10-11 days off depending on the month. I personally broke reserve guarantee on the emb, but not sure about the guys on the rj. Lots of new shiny jets coming though, so if you get on soon, it's not going to be too long to getting a hard line. If you have the choice though, for quality of life while commuting, request an emb class, pay is the same the first year, and you'll get off reserve very quickly which means a much better schedule.
Hope I answered a few of your questions. PM me if you have any others.
later,
Mookie
