A MFF Airbus Captain in Charter world would be (fag packet) @500 hrs pa.
For this there is a salary @£110k+, PHI, 8x salary death in service, co pension of @15-20%, nice hotels and plenty of time off per year and per month.
If I was said Captain
my choice would be to go half time at the airline and still earn more than an Airtanker crew
As has been said previously in this thread, the package needs to be extraordinary to winkle out Civvy pilots from their comfort zone.
