The TSA program requires you to go to indoc to start seniority. You only get 90 days of seniority before you have to be in ground school. If you don’t make it by then it’s still just 90 days on a rolling scale. Now one thing that I’ve seen people get confused about is the difference between seniority and longevity. Most of the rotor programs and cadet programs let you build longevity with the company while in the program but not seniority.

An example: If you’re in a cadet program for 9 months and training for 3 months it is possible to hit the line on year two pay but your seniority will be based on the day you went to indoc or 90 days whichever is closer.
