Initial reports indicate that we received several passenger complaints characterizing the behavior as excessive. Our crew, responsible for the comfort of all Customers on board, approached the passengers based solely on behavior and not gender. The conversation escalated to a level that was better resolved on the ground, as opposed to in flight. We regret any circumstance where a passenger does not have a positive experience on Southwest and we are ready to work directly with the passengers involved to offer our heartfelt apologies for falling short of their expectations.
