Generally you get 2 days off after a longhaul trip or a block of shorthaul. For example I have had something similar to this -
Mon Report 0945 LGW - MCO
Tue Depart MCO
Wed Arrive LGW 0630
Thu OFF
Fri OFF
Sat 0700 check in LGW-MAD-LGW-GVA (nightstop GVA)
Sun GVA-LGW-AMS (nightstop AMS)
Mon AMS-LGW-FCO-LGW Finish 1545
Tue Report 0945 LGW-MCO
Wed Depart MCO
Thu Arrive LGW 0630
Fri OFF
Sat OFF
You get 3 days off if you do a 7 day longhaul otherwise it is just one or two days together and a total of 9 a month.
