In short, no. The degree will give you no advantage going for a pilot job, it may give you a small advantage going for any other aviation job but not pilot.
I looked into this course and the degree just seemed to be there for the sake of a degree. Most other aviation jobs you can get without a degree (with the exception of engineering)
Im not sure on the prices but if i remember the degree/cabair option was more expensive then just going through cabair.
Have you thought of doing a degree other then aviation related? With the current climate in aviation after your training you might not get a job and a degree in another topic might be something to fall back on. Also you dont want to be getting into debt at the moment. Read these forums for a while and you'll get the feel of timing is everything. In two years they could be crying out for pilots, or the situation could of got alot worse and you'll have mounting debt, no job and no degree to fall back on to go into another career. Just a thought, goodluck whatever you do!
