Ocean crosser gave you an idea. ACMI (Aircraft, Crew, Maintenance, Insurance) 4000 quid. You DO have ACMI costs, even if you own the aircraft yourself. That cost probably includes most of the fees minus the fuel in Scotland. Then fuel at 5000 pounds and any associated charges at the destination. Remember, if landing costs are not already free at the destination, it WILL be added to your ticket price. A lot of airports charge per passenger, for example 5 quid a head. This will most definately be added to your ticket price. Id say between 8 and 10 grand to operate.
