Piloting airliners is a big deal. I am not sure if there are any age restrictions in the U.S, but I would look into getting a few lessons towards a pilots license. Be sure that you want to pilot a normal plane first before you jump into a commercial plane.
Structural Engineering requires physics and advanced mathamatics alongside the engineering parts, and will probably require even more training than pilotting, but ultimately it will lead to a broader choice of career paths.
Hmm... Just got a phone call and lost the thread of my thoughts so I shall leave you with what I have already written - It sounds fairly complete anyway.
Just try not to worry too much whilst you are still young.
