In my humble opinion, you should get a degree in something else than aviation. An aviation degree won't put you ahead of somebody that has a Business degree for example. As far as Airline go, it is a box that you mark or not. But in your down time from flying (Remember that the only thing certain about flying is that certainly your employment is fragile, at best) A degree in aviation won't do anything for you in terms of supporting your family while you go on trying to get another job in this here paid hobby of ours.
Good luck on your decision
