I was in a similar situation about this time last year except for the seniority. I was also hired in June 2007, and furloughed in early 2009.
I came back to TSA last spring, went through training with no problems and expect to upgrade this spring. It’s a different place than it was when we came through the first time. Some of the rotor guys in my class had 14 or 15 sims before their check ride. The training department has added so many extra GFS and SIT sessions that anyone with previous time in the airplane will be bored.
Get in, log some time, and move on.
