Not sure if this applies exactly to you, but as someone who's getting a degree in preparation for applying to the FAA Academy here in the US, the Collegiate Training Initiative (CTI) sounds nice, especially because it only takes 2 years to get the specialized degree, but with new hiring standards and procedures, it may not have much future in the US. Personally, I'm aiming for a 4-year degree in Aviation Management, but it doesn't necessarily have to be an aviation degree (I'm going that path since if I don't get in, I could always work in airport management, or something like that).
Regarding the psychological factors, the FAA takes a lot of precautions these days. If you get accepted, before you even get into the Academy, you have to pass 3-6 weeks of psychological testing.
