You are partially right to be nervous for the future at any regional airline. You've probably seen all the retirement/hiring numbers and can see that the regionals won't exist in their current form or even exist at all 5 years from now.

The good news is that you should be at a career airline between now and then. You have a skill that is in great demand to many companies.

Do well in training, keep your nose clean, network, and do something's that are above and beyond to make yourself stand out from the crowd and you will be at a career airline before you know it.
