But how many journeys are made with all seats full?
I have never had 4 in my aircraft, rarely 3, occasionally 2 but usually 1.
The best option is the Mooney ovation 2 with long range tanks.
I has a greater range than most executive jets and cruises faster than most twins burning far less fuel.
If there are 2 of us then we can top the tanks. If there are 3 than we can fill to three quarters, If there are 4 then I would fill to half tanks.
Half tanks in the Mooney means I have the range of a Cirrus.
