No, they would have held a line instead of reserve IF we still had SILs.

We pulled them down (for good reason), so I will be flying a line in September. Someone junior to me could have had a line instead of reserve if I was at home on a SIL instead of flying 75 hours in Sept. The point is that SILs aren't automatically bad for pilots on reserve. Some of them would be lineholders instead of reserve, because pilots senior to them are out on a SIL.
