Contractually you get a minimum of 10 days off in a month. You may take them consecutively. If you do, you will gain 2-3 extra days off to comply with the 1 day off in 7 days rule. The only penalty to you is loss of flight hours that will take you below the 80 hour minimum for a business class ticket home. Since you're on salary no pay loss.
I take them consecutively. In fact I back up the last ten days of the month with the first ten days of the next. In effect then I take a three week holiday every six weeks. It does mean though I work six days in a row with a mix of one to four day trips. Typically I'm at my apartment 3-4 nights a week during that six week stretch.
There's a million ways to skin the SKY cat though. YMMV...
