There are many reasons why a group may charter a private flight when they need to travel, but few have nearly as high stakes in transportation as a professional sports team. The difference between getting a team full of players an extra hour of rest can mean the difference between winning and losing, and for the owners of professional sports franchises, this can mean millions in additional revenue. As a result, airlines will often turn to charter flights due to the added convenience that they can offer, with private flights allowing passengers to bypass security checkpoints by using private terminals.
