I need to learn me some golf

There are thousands of corporate aircraft flying the skies over the U.S. Most companies say these planes are necessary to conveniently and securely transport employees to distant facilities or meetings. Top executives "are really 24-hour-a-day, seven-day-a-week people," notes Mike Nichols, an official with the National Business Aviation Association, a trade group. "These are really flying offices."

But a comparison of golf scores and flight records, some of which are available from commercial aviation-data services, shows that companies also use their jets for another purpose: as airborne limousines to fly CEOs and other executives to golf dates or to vacation homes where they have golf-club memberships.

There are perks and then there are perks.
