Hey Bo,
The FAQ section is a really helpful resource that can answer this question, as well as probably a lot of other questions you may have! 
The main excerpt you need is as follows:
Summary
The answer to this is both yes and no.
No. To be hired at a regional airline there is no requirement for a college degree, in fact the regionals very frequently hire pilots without degrees. The regional airlines are hurting a bit for pilots and are mostly concerned with a pilot having their 1,500 hours, having a good track record with the FAA, a good driving record, no criminal history and the pilot being a good guy or gal to work with.
Maybe. Many of the National, lower cost airlines, such as Spirit, Sun Country, Frontier, etc prefer a degree, but do not require one.
Yes. The major airlines absolutely require a bachelor’s degree, in any field, from a reputable university or college. When choosing a degree major, choose something that you not only enjoy, but also think you could fall back on if necessary. Now let’s talk about the reality of when an airline states that a degree is “preferred” vs “required.”
