Deadhead pay is 75% of scheduled block. Scheduled being the operative word. We dead head all over creation and back. If it's a company aircraft, we've been getting away with getting 75% of actual block due to some software issues. We regularly DH on other carriers and only get pay based on scheduled block regardless of how long the flight actually takes. I've spent over two hours in the back of a CRJ in the penalty box in ORD completely unpaid because the scheduled block was only 1 hour. So, 45 minutes of pay for 3.5 hours in the back of a CRJ. To add a little salt to the wound, I was removed from my turn out of ORD because of how late we arrived at the gate. No pay protection for that plus a 3+ hour sit before flying off to my reduced rest overnight. This was well before part 117 was even a dream.
