As a relatively new guy, I'm don't understand PBS very well...so I need an assist. I've been a line holder for a few months, and was expecting a line again...why not? My bid is easy, just a couple Award lines for 4 day trips and layovers at home. I have a carryover trip, that has 19 hours of credit into Jan. When the schedule came out, it gave me reserve...happened to a few of my buds as well. Here's what the Reasons Report says:

Bid group not attempted: Previous pairing bid group could not build a complete line

What does that mean? Why do so many people below me have a line when they had holiday trips as well?

Help!
