I would not use a degree to get a job to pay off my training unless that job was in aviation itself.
The best advice I can give you is after your training go and work in aviation. Baggage handling, operations, cabin crew etc. Literally anything.
Don't finish your training and then use your computer science degree to work in IT until an airline job comes around. A job will come around, but the best thing you can do is get involved in aviation right away, be that as a pilot or not.
And even if you have a degree, there is still issues with getting the job you want right away no matter what field you are trained to work in.
