Not sure what you were saying about international airspace with regard to FAA requirements. If you have a 10 hour flight, which is 600 minutes. The FAA requires 10% contingency fuel or 10% of 600 minutes or 60 minutes. The requirement is based on flight time from take off to landing. The fact that the first two hours are in domestic airspace has no impact on the fuel requirement.
