HJ,
Not that old chestnut again! That's like the other old chestnut that the oil companies were paying for Business Class airfares for us.
As a past Base Manager I have read many CHC / Oil company contracts and there were no separate amounts tabulated for crew unless the oil company decides to add a crew, ie night standby crew, after the fact. The oil company stipulates their crew requirements in the tender and CHC includes that into the monthly and hourly aircraft rate. Remember, you are just an aircraft component.
You are right about the justification for the pay difference between GO and Europe but you aren't listening about the difference between GO and the locals. The locals are employed by their local company or government. CHC is usually a minority partner in these deals and other than utilizing the crew that they are given, have very little say in their employment details.
Hey Delaminator. How's it going B'ye?
