Do you have any certificates or ratings yet? If not, I would say the general consensus on this board is to go to a local FBO to obtain your Private Pilot certificate to make sure flying is for you before you invest thousands upon thousands of dollars into flight training.
After that, and knowing that flying is for you, go visit each place you might think you are interested in. I'm looking to go to ATP in Manassas next year. It is an intense, accelerated course that seems to deliver what they tell you. A lot of students will go to Delta Connection Academy (Comair) or Mesa Pilot Development for their connections to the regional airlines.
I encourage you to spend the majority of your time here at Jetcareers on the bottom half, reading everything you can about the numerous flight schools/academies posted on here.
Good luck and happy hunting!
