Marcus,
I personally feel that the best path is to go to college, obtain a non aviation degree and then go to a school that offers accelerated flight training. The major airlines are going to want to see a degree, so it is best to knock it out while you are still in the school mode.
The Air Force is a great way to go, but unless you go to the academy you will need to graduate from college first if you want to fly in the service. Contrary to what recruiters will tell you, there is very little chance of you ever flying as a pilot if you enter as an enlisted and not as an officer.
I would strongly recommend that you take an introductory flight. You can do this at your local flight school or at an ATP location. It is one thing to ride in the back of an airplane, it is another to actually fly it. Only an introductory lesson can help you see if you really want to fly for a living.
