Ultimately it is Engineering and Science that make aeroplanes fly.
But it is languages that allow us all to talk about it - so that's not a bad option if you are set on a degree.
But (and I say this as somebody with a CPL and two engineering degrees) I continue not to believe that a degree is really of that much use to an airline pilot. (The other way around, I use my flying knowledge daily as a Chartered Aeronautical Engineer.)
A flying instructor making their career that way might well use business management qualifications, military pilots - being also usually commissioned officers are preferred to be graduates, and test pilots usually have engineering degrees. A proportion of airline pilots will go into management, and business management type qualifications then become of value to some.
But if your ambitions are no higher than airline pilot, then I continue to believe that you're better of knuckling down with the flying training and maybe thinking about a part time degree later when you have an income and standby time.
