Assignment pay for reserves for an illegal rotation is the value of the first day of the rotation (block + DH + MU). 2:00 is the duty period minimum so you’ll never be paid less than that. Other than that the top end is the amount you block/DH. I chose 8 hours as an approximate max for NB pilots, but really for WB pilots it’s up 2 to whatever our longest block flight is (16-17??).
