For those of you willing to read through all of this, I'm hoping some of you may have a similar experience and can offer your 2 cents. I'm currently a FO at a 121 regional and have been there for about 1.5 years. The pay is what you'd expect given that it's a regional, but things are improving...bonuses, commuter hotels, etc. It's likely that I'll be stuck as FO for another couple years at least. The kicker is that I have a fairly long (2 hr) one leg commute just to get to base and no matter what 121 job I have, I'll more than likely have to commute. So, recently I've been given a tentative job offer flying a mid size jet based at a local airport 15 minutes from my house. It would be corporate flying for one owner. No charter and the flying is primarily for business (they fly 200-250 hrs per year). The pay would be roughly what I would make as a captain at my current airline and the benefits are pretty good. From what I've gathered, it seems they run on a weekly schedule and usually have 24 hours notice at least for the occasional pop up trip. To keep this from turning into a novel, I'll get to the point. In the short term, this job seems like it's significantly better than life as an FO at a regional. BUT with the corporate job, the future is unknown as far as career progression. With my 121 time I currently have and the time I pick up flying part 91, would I be a candidate for a LCC or major should I choose to go back to a 121 in the future? Again, none of this has gone into motion yet, but I would love to hear what you guys think about a scenario like this.
