Options other than humiliating a 69 year old: Don't wait until the last second to reserve crew transfer seats, put your crew on another airline, put your crew on a bus to Louisville or pay one of them to drive a rental car (only a 5 hour drive), find replacement crew in Louisville, offer more compensation and a hotel room for the night to another passenger. Let the dude fly and then file a police report against him for not obeying their ridiculous law. Poor management. #UnitedAirlines
