The answer above my reply is the exact way to determine it, but if you’re not a part of the company yet, then as an approximation, once you reach 80% seniority, you might be able to hold a hybrid line (part reserve, part line) and then once you reach approximately 70-75% seniority, you might have enough to hold a line all the time. It’s impossible to give an exact number because the amount of flying changes every month so it’s somewhat of a moving target.
