Q: When can reassignment occur?
A Flight Attendant can be contacted for a reassignment on any “days on” of work, that is between midnight of the first day of their original sequence and completion of their original or revised sequence, as appropriate.
A Flight Attendant can be reassigned any time after their scheduled initial report time (i.e., at the start of the sequence). A Flight Attendant cannot be reassigned while on a layover unless the Flight Attendant answers or returns a call from CS.
