Let me be upfront as I probably already know the answer. Just want confirmation.
If you are below the g-line and have carry in time from previous month. Does seniority matter at all to building lines?

For example
Pilot A has 18 hours carry in and waives everything. Gets reserve line for Jan.

Pilot B is junior to pilot A. Has 18:01 carry in waives everything and gets a line.

Is there any validity to a pbs dispute?

My basic understanding is below the G-line all bets are off.

Happy holidays.
