Delta is introducing a scheme that will let you trade in your basketball tickets for round-trip flight tickets, all to benefit charity. If you have a ticket to one of four L.A. Lakers games this season, you could exchange it for a round-trip flight to any U.S. destination. The "Showtime Seat Exchange" will give you as many vouchers as tickets you trade in (up to four), so you could take the whole family on vacation in exchange for tickets to one basketball game.
