Anyone fed up with the security lines and cramped seats that come with commercial air travel has dreamed of flying high in a private plane—but not everyone can swallow the price of buying their own. Enter the jet share. Fractional jet ownership lets you buy time on a private plane without owning the whole thing (or finding a place to park it)—kissing airport hassles goodbye. Major companies offering the service—NetJets, Flight Options and Flexjet—have a range of options for private flying, and are growing, too.
