Do you have a Private Cert yet? Start there at your local flight school or an FBO that offers flight instruction. Visit www.beapilot.com
and get the $49 intro flight certificate. Join Aircraft Owners and Pilots Association www.aopa.org.
I recommend staying away from a 141 school for the private because you'll wind up flying about the same number of hours but you'll pay a heck of a lot less under part 61.
I too would love to be an airline pilot, but honestly, for someone our age (I'm 28 and well embedded in my career) it might not be the best thing to dive into head first. Get your feet wet with a Pivate Pilot Certificate, see what you do and don't like about flying and flight training, and see if you still feel the same way. Maybe it will satisfy you to be a weekend flyer....
I warn you off because it is a huge expense in exchange for not much compensation if you head off to one of the big name "airline training schools." The ads I see all the time quote prices around $35k for the fast track programs (where you can't really work on the side) while the regional airlines advertise starting salaries around $20k per year (assuming you can get hired).
Get your cert and have some fun. Make sure you will keep having fun. Get your finances in order. Look with scrutiny at the big, well respected schools to see who offers the training product that matches your needs and wants (its probably going to be in florida!). Then get moving on with the dream.
