Flyboy, I sincerely mean no disrespect to you when I say this, but are you as exhausted firing out posts obsessing/complaining about things you can’t control as I am reading them?? Seriously, chill the f out. Obsessing about things in this industry you have no control over will do absolutely nothing to help you and will drive you to insanity. Don’t put yourself through that.
What you should do is analyze what your goals are, pick a regional that will give you the best means to get there (maximize your QOL by living in/within driving distance from base if that’s important to you, or fly your butt off in the right seat/left seat if building 121 TPIC quickly is important to you), focus on learning the operation and airplane you’re flying until it’s instinctive, and get through probation. The path to a legacy is a marathon, not a sprint. It takes a few years. And since age is a factor for you, the LCC’s offer similar pay, benefits and QOL as the legacies. And they don’t even necessarily require TPIC to get hired.
