usually 3 sectors a day (up to 2.5 /3 hours in length) to include a night flight but on the odd day you could get 4 sectors in -
other days maybe 2 longer sectors like TFS or LPA in the morning and HER in the early evening
at OM/MON we had an 0200 dep LGW-CFU on a Monday night (Tues morning)
the 737 had already done 3 rotations on that Monday thus making 4 rotations
