In the past, once a Reserve Flight Attendant picked up a pairing on her/his days off, if she/he later wished to drop the trip in exchange for days off to another Flight Attendant, Crew Scheduling had to be involved in order for the trade to be processed.  As of December 5, 2019, Crew Scheduling is no longer required to assist in these trades as they have been automated and the defect has been fixed. As long as the trade is legal, it will be processed automatically if trading with a Flight Attendant at the same base. 

Keep in mind, however, that an out of base lineholder looking to pick up a trip from a Reserve on days off will be required to contact Crew Scheduling for assistance in processing the trade.
