Thanks for doing the sums, I've always wondered how much it cost to do a run to Calgary. As for the extras etc it truly is shocking, I was always suspicious of the up front drivers when we always seemed to break down in Washington on the way back from Belize and actually on the tarmac at Calgary.
That Calgary breakdown cost the MOD a fortune in hotels, Pay per view movies, food etc but for some reason they insisted on flying the spares from Brize on another T* rather than paying $10,000 Canadian for the part from a maintenance company across the runway.
