Basically unless you bid split lines. You're still on the hook for 16 days with the 17th day at their discretion. This month I sat at home day 1 on scal and looks like I'm headed home a day or two early on this sequence that rolls into next month. For May that would have been 16 days straight at home, except that I did pick up 2 days which had them use the override day as a result, giving me 3 days over guarantee with the extra 300 and 400 per day on the volunteer days. In the end my month will be 13 days home with about 80 credit plus $700 with about 48 hours of block flying. Hope that example sheds some light on schedules and how it can be worked for pay.
