The company has a very effective roster swapping system to ensure all pilots get the flying they want, run by the special CSDs (Crew Shafting Department).
Yep, roster swaps are allowed that suit the company at any time. Simple examples include 7 double back to back Dohas instead of a Melbourne, forget a nice cushy flight to London at 9 am why not try the Dakar leaving at 0045 with a 3 week lay-over in a tent.
So that individual pilots do not feel disadvantaged, they can have the pick of the available swaps to India every 29th February.
Hope that helps!

P.S. Ok the real skinny is one crew initiated mutual swap/month but the credit doesn't change hands. It used to be unlimited and this is still the case if the company needs something from you and your negotiating skills are up to scratch. So you will never get a consistent view
