They go super senior. The OT CDO trips go super senior on reserve as well. Imagine 5 days of reserve doing a RAP 3 that starts at 7pm on day one. Day two getting a CDO and Day four getting a CDO. This means you know for a fact that you won't show up to the airport on day two before 8 pm. And you get 30+ hours off between trips and finish at 7 am on day five.
