You would get PB days in your bank. You can use the PB day the next month or down the road if they have resv coverage on the days you want to drop. If you have a line the next month you can drop a 4 day trip if they have coverage for the 4 days and you had 4 PB days in your bank. Best bet is you request your PB days on the 1st PCS run on the 20th of the month. You can also GS on you PB days unlike a PD or a APD
