They didn't know?
When they got to Miami, they knew. That bullhorn and people hanging off the Western U had to make them think that something was up. Maybe the car of people who followed them to the hotel may have jarred their memory. Or the other half-dozen flights that they did may have convinced them that something was amiss. You know what an American does? ABX had a contract, their pilots didn't fly, Tradewinds pilots brought an aircraft to Miami, and then refused to fly. Every other freighter, including Tampa, won't fly charters. Saying that these clowns didn't know anything until they hit Miami is just b@ll!!!!!. Have a nice time in Toledo with our union brothers.
