The "aviation" degrees are largely useless in the real world, except for actual engineering degrees. Get something that will allow you to earn a living in case aviation doesn't work out. You can also assume that you will get a 2-3+ "vacation" from aviation at some point due to layoff or medical problems.

For the most part, airlines don't care what your degree was in at all, however a challenging degree like science/engineering or a masters will make you somewhat more competetive at the major airlines.
