It depends: if you want to make money, get your CPA or a law degree maybe.

The airline industry is in bad shape these days, and as usual, the rank and file- including the pilots- are getting the worst of it. Entry-level pay for flight crew is not very enticing.
And even in the best of times, it's been a competitive business that requires a very serious commitment... even in the glory days of airline flying, the road to senior captain, with your pick of the juicy routes and schedules, with a fat paycheck and excellent benefits was a long hard one for most pilots.
So now more than ever, it's wise to have a "Plan B"... airlines don't really care if your degree is aviation-related, although they like to see applicants with a college degree of some kind, so a degree in some "fallback" field is a smart move, even if you really want to fly for a living.
There are a number of aviation degree programs out there, though, most of which include all the flight training... I suggest you google "aviation degree".
