To add onto what TP says....

I've not seen for many moons a roster from scheduling with 15 days off on it... for Boeing captains anyway. I generally get about 9-12 days off and I think that's more the average than 15, but again that's not for FO's but for captains.

Really the only way to get 15 days off a month is to trip trade. Also be aware that you cannot get more than 15 days off a month. You can't just trade your schedule away like in the US legacy carriers and fly 6 days etc. And as TP mentioned, only 7 days off in a row maximum!

330 guys both left and right seat do fly only 60-70 hours a month but they have to fly 20-22 days/month to get that since they do mostly turns of a shorter duration.

Also.... you don't just bid for 3 ULR's here and be done with the month. You can only have 2 ULR's per month so you work more days to get your hours (90 plus as captain here). There may be some ways to get a 3rd ULR with trip trade/swap system.

All in all, it's nothing like back in the US regards to schedules...

I've actually heard the head guy at EK say that to work less than 15 days a month is "stealing from the company".
