If you have a job with a regional, you're on your way, but not to making any big bucks anytime soon. US regionals' company cultures and career opportunities vary widely.
The majors and LCC are hiring (for now), but competition is keen. The whole
airline pilot career has been drastically changed by economics and politics.
The national carrier model, where pilots were supported by the state, is largely gone in Europe. Deregulation in the US has provided more jobs, but longer hours and lower pay.
If you haven't seen the light reading all the stuff on PPRUNE, read it again, then decide if you still want what passes for an airline "career" in the real world of today.
Good luck!
