Flying privately to Louisville for the Kentucky Derby has become as fashionable as wearing an elaborate hat to Churchill Downs on race day or ordering a mint julep in the grandstand.

The charter company Victor reports a 21 percent increase in charter requests for Derby weekend this year compared to last, and the membership-based private-flight provider Wheels Up has seen a 35 percent increase in bookings. As demand for private flights to the event continues to rise, some companies are offering their clients and members special Kentucky Derby packages. Continue on to see five of them.
