Thanks for all the input guys. I am aware that 4,500 TT is not really that much when going against guys that have been airline flying for years. When I read that Alaska has 2,900 applicants for 80 seats, that was very sobering. Knowing that there are guys out there with much more time than I have and lots of 121 experience applying for the same jobs I will try to get does not give me high hopes.
My big worry was that I could find myself too low for a major, but too high for a regional. It is good to know that there will be places for me to hang my hat when I get out.
