Don't expect an easy roster, I have spoken with dozens of former and current Lion expat Capts. Often working 6 days on 1 day off, schedules changed late the night before, being asked to fly on your day off etc
Senior Indonesian Capts keep changing their schedule asking for easier or preferred flights. A few expat Capts have even referred to having their FO taken away from them after reporting for duty by a high status Indonesian Capts who like flying with the FO, on some occasions literally while walking to the aircraft!
Scheduling and rosters there are a mess and have been for years.
Perhaps it has all recently improved ......?
