I think that something that a lot of people outside of the regionals fail to realize is that there are a ton of guys that are at the regionals for life for various reasons. When I was instructing I had the false impression that everyone used the regionals as a stepping stone to the majors. I assumed that it was just part of the natural progression that a guy would put his time in at a regional and almost automatically move up to a major.
Now that I've been at a regional for a few years, I realize that lots of guys just stop at the regionals and never move up or even want to. I don't know that I agree with these decisions, but I certainly understand why some guys end up in such a spot. In the last three weeks, I've seen two captains reach 60 and retire. I used to think that was unheard of at the regionals.
We have quite a few military guys that came on during the early 90's when hiring was bad. They have good Air Force pension and make about 80-90 grand at the airline and are perfectly content.
A lot of guys are from the area that they are based and have no desire to move and will not commute even for a major. They make pretty good money 60-70 grand on the t-props and 80-100 grand on the jets or training department. They are very senior and pretty much pick their trips, days off, and vacation.
Many guys, especially these days, enjoy the job security that goes along with being in the top 25% of a seniority list and feel that the benefits of the majors do not outweigh that security. We have hired many furloughed mainline guys that claim that they may not go back to their majors if they are in the top 50% here and in the left seat of the jet. I don't know that I believe them, but it's what many say.
Some guys fear going through training again. Some guys were simply unable to get hired.
I don't agree with many of the reasons for staying at a regional and I believe that even the junior guys at a major enjoy a better QOL and pay than even the most senior guys at a regional. Having said that, I can see why and how guys get complacent and really lose any or simply have no desire to go through interviewing, training, and being on probation all over again. I can fully understand how guys in their forties (I'm not that far away) with a mortgage, a few kids, non working spouse, etc. fear the risks involved in making the leap to a major. Plus, it is a big pay cut for the first couple of years. The pay cut more than pays off in the long term, but many of us live pay check to pay check and couldn't afford it--others couldn't afford not to.
I think that if you have not made the move to a major by age 45 and you're making enough to live on and retire on, you should probably stay put.
