From speaking to them about this course. The whole reason is so that you do have a degree to fall back on if the airlines do take a tumble or you do lose a medical.
All other employers look for potential employees to have a degree in something as it is a requirement to hold a management position. The subjects outside of the ATPL cover areas which would help you get a job in the airline industry such as ops manager, flight planner, airport manager etc.
They said that the subject choices had been determined from consultation from staff in Aer Arran, London city University which runs a similar programme and with Waterford Institute, also I hear Embry Riddle from the US were involved and they are one of the best at these type of things.
As for whether it would get you an IT job or something like that I don't know . But still it is good to hold a degree of some sort.
