I'm also in the same situation.
Think if another 9/11 happens. What then? The pilots who are laid off need to find a job to support themselves. If you have a degree that was taken 20 years ago it will always get you a better job then plain A-levels. It doesn't matter how long ago it was. Do you not go to Hospital and see 50 year old doctors practicing medicine?
WWW can't see 40+ doctors because their degree is covered in dust???
Everyone knows having a degree does no harm. I bet the life experience you gain from the 3 years at uni is a lot better than the experience you get working at Tesco. Any degree helps a pilot. Just like you said, pilots need to know a little bit of everything.
Just saying my opinion.
