I see more peoples calendars with a light green Rx line after their dark green R-days. Sometimes there are trips overlapping , other times no trips overlapping. I remember reading in the new contract that we could voluntarily add Rdays to our calendar. I do not see anyway under Bidline adjustments to add Rdays to your schedule. Anyone else know? This is on B777 Capt calendars. Some guys have all green for their whole month between regular Rdays and these Rx days.
