My understanding is that OSM aviation, who employe the short haul pilots will in due course become the employer of the long haul pilots. Lets be clear this arrangement is very different from say Brookfield.
Pilots employed by OSM pay taxes and social insurance in the countries where they are based.
The long haul operation appears to be reaching a critical mass, with 8 in service and 4 more due in 2016, the loads are reported to be very good. The 787 is settling down nicely.
