Spoke with a rep a few days ago. He said at that point we had had a half dozen given a PD for acknowledging inside 10 hrs and had the trip dropped. He said they'll be filing a grievance. I also saw a trip where a pilot's rotation started with (as in was originally scheduled) a DH and then another leg which put the pilot past the Max Duty day and required him to fly into his 2 hour extension. This was how it was built. Said rep said he would not have accepted the trip as it was scheduled. I don't know what the pilot in question did. Point being: look out for trips built that have you flying into your 2 hr extension from the get go.
