But I do not think you can drop a trip just because you have PB days.
Pretty sure you can use the PB days one at a time. However, when you use PB days, they are not like a APD or IVD. The coverage has to be positive.
Edited to say I was wrong. Just looked at PCS and looks like you drop the whole trip and then it’s applied against your PB day balance.
