Depends on your seniority on the list. I was about 70% when they started the pre-assigned RAP B.S. I was always able to proffer out of it (usually a PM ready shift) or get a later trip.

It also matters where you commute from. I live in a very commutable city with 12-14 flights to DFW and ORD per day. I've never had to fly in a day early or stay a day late.

Commuting to reserve ain't no picnic, but it's not the worst thing in the world either.

As a junior line holder, I have averaged 13 days off.
