I am a new hire, and I have been looking deep into the handbooks to understand reserve and scheduling.

however, one block doesn’t fall in place, maybe someone can clarify for me….

what’s the earliest I can request a YS? Let’s say I start a LC on Friday, and I see an open time trip that I would like to fly during my LC period, can I submit a YS for that trip say Monday or Tuesday prior?

thanks everyone!
