Personally, I'm biased for getting a degree. I did it myself before starting flight training and it worked out great. It gave me a nice paycheck, valuable experience, a strong CV, and the peace of mind that if I lost my job in the deck tomorrow, I'd be back in an office next week.
I tend to agree. More education is never a bad thing, and you never know where you can put your degree skills to use in aviation. Many pilots end up in the office at some point in their career, where suddenly those stats and creative and technical writing courses begin to make more sense. For some, like me, education becomes a hobby in its own right, so having a degree or two is nothing more than the end result of that hobby. I'd argue that in many ways it's a pretty cheap hobby compared to others, but I digress.
Not all degrees are created equal if you are looking to simply pad your resume. Just because you have a degree in a field does not mean you can immediately return to that field should you find yourself an out-of-work pilot, which is what most suggest is the reason for getting the degree. Many degrees are useless after only a few years if you don't continue to study or work in the related field. Therefore, my typical suggestion is to get a generalized degree that you could build upon in the future, but not so specific that you may as well not hold that degree later five or ten years later. Alternatively, you could mix your passions. We have two pilots at my airline who hold doctorates and who split their time 50/50 between flying and research, and many more who have built a business around their education or who continue to study so they can use their degree later on.
