If another base does not have the reserves to cover it the trip may go to another base's reserves. They put that in there so it doesn't go through the whole trip coverage process in the new base. I've gotten a few of these assigned to me on reserve so I started looking at the reserve availability list from that base. They had more than enough coverage so I took screen shots and sent them to DALPA scheduling. They felt the company violated the PWA by working around the trip coverage sequence and filed a grievance. It's good to break out the PWA once in a while.
