Commuting to Allegiant can be tough. I was there from Feb to Sept of this year. I kinda wish I would have stayed. The big thing is if you have to commute make sure you get a good place to stay. I stayed with a college friend and did not mind it at all, I was comfortable. Although the biggest drawback was that I was still only home 1 1/2 -2 days most weeks. I would guess new hires could expect one of the new bases opening in the end of the year.
Reserve can be slow if you are stuck on it for a while. 2 or 3 of the months I was online I only flew 20-25 hours. Great if you live in base but not so hot if you commute and just sit there.
Good Luck!
