Consider this.
US airlines don't really care what your degree is in. A degree in 'underwater basket weaving' is fine so long as you've checked the required box. I've frequently told wouldbe pilots to go and get a business degree. This is a crazy industry. Especially since 9/11. If your airline starts to furlough pilots they'll start at the bottom and work up. On the street, a degree in Pro. Aeronautics won't impress anyone.
My degree is in mechanical engineering! Never used the darn thing!
Good luck.
