On average it is 8 with minimum of 7, but it also depends on the fleet type you're on. A320 generally is the worst. It is a transitional fleet where you get your new command or come on as new-hire and just deal with the crap for approx. 18 months or so until they hopefully (or as they say here "inchallah") CCQ you over to something bigger. Compared to 'US' standards of days off and roster flexibility, forget about it. You are here to work for them and work you shall.
