Most of us do not think of family until it becomes a situation. I am not that old and not ready to settle down until I get into a flight deck of an airline. Any airline.
Anyone can tell you how a lot of people came up in rankings. Paid for their own flying, WHILE holding a job. Do small things to build time, ie...tow banners, gliders and stuff. Getting a CFI to teach people to fly just for the hours, roughing it with small regionals (turboprops, loud sweaty cramped cockpits), bush flying and so on.
That is determination. Can any of us afford being a pilot? NO. But do we try? Hell yeah, coz that is what we want to do.
As mentioned by Sandwich, I think you really need to get into a cockpit for a familiarization flight, won't cost a lot, and see if you like it. If these airlines only pay 15K a month, would you do it? Or you would find something else?
Be what you REALLY wanna be, I would hope you don't feel like you entered the wrong field when you are aboard.
Take this msg like advice. Never ever mention money unless you are qualified.
