A method includes a step of effecting a purchase of a first aircraft by a
first plurality of fractional owners. Thereafter, a lease is granted by
the first plurality of fractional owners to a first entity, the first
entity operable to coordinate maintenance and operation of the first
aircraft. The first entity is provided with a first fee payment in
exchange for the coordination of maintenance and operation of the first
aircraft. The method also includes determining a use allocation for each
fractional owner in an amount based on a fraction of the first aircraft
owned by the fractional owner, the use allocation comprising a measure of
flight usage of one or more fractionally-owned aircraft including the
first aircraft. The method further includes reducing the use allocation
for more than one fractional owner after a single flight that includes at
least one passenger associated with each of the more than one fractional
owners.
