Alternatives to commercial air

Fractional ownership: Example: NetJets Inc. Upfront costs start at $400,000 for a 1/16th interest in a plane, equal to about 50 hours of annual flying time to destinations of your choice, plus fees of around $15,000 per month and $2,000 per hour of flight.

Fractional jet card program: Example: Marquis, a NetJets affiliate. You buy 25 hours of flights per year for prices starting at $110,000. You decide where to go but subject to plane availability and 10 hours of notice. Unused flight time expires at year end.

Private jet membership: Example: Sentient Jet Inc. For $100,000 initial membership deposit, members can get access to about 900 different planes for rates of typically $2,000 to $6,000 per flight. Ten hours notice required.

Scheduled charter operators: Example: Linear Air. Service is on small fancy planes that fly set routes between small airfields up to four days a week for a fixed fare, such as $438 per round trip from Hanscom Field to Teterboro, N.J. or White Plains, N.Y.
