The original Captain on one of my trips for Sept. was removed for some reason and a Captain from another crew base was assigned to the trip (weird), but obviously a different paring number. On the new Captain's pairing it has "(TRN)" attached to the pairing. I'm assuming that means training, but I've never seen that attached to a pairing. Does that mean I'm on the sucky pilot list and need extra training? Anyone else ever seen this? thanks.
