Honestly, I don't know if the average guy of IP age would likely tolerate the lifestyle or "professional environment" of being a year 1 regional pilot. Now that I'm no longer in my 20's and now an IP, I wouldn't do it if faced with the same decision today. It worked for me and was a lot of fun in the last decade as a young guy enjoying the crash pad and young crews while having a supplemental income that made it so I could afford to buy the next round.

Since the OP is a co-pilot, he needs some turbine time and the current budget situation may make it difficult for the next couple of years without selling himself to volunteer desert rotations.

In your case, probably depends on the airline and how well networked you are if 2200 TT is enough as an IP to get a look as a non-fighter guy.
