Nolimit,
The Pax on those sectors are either Canadian Citizens of sub-continental ancestry visiting family, or family of those same Citizens visiting their Canadian relatives.
In either case, they are Canadians who want the service (with the exeption of the guys being visited by the Mother in Law).
Of course EK isn't being ultruistic. It wants nothing more or less than to profit from supplying a service for which there is a demand.
Why should they not be allowed to?
As to the "Exhausted Crew" crack, we are working hard and flying to limits of our FTLs.
FTLs which are MUCH more restrictive than those which apply in Canada or the US.
