He described the man as "disruptive and belligerent."  By Tuesday afternoon, almost two days after the Sunday evening confrontation in Chicago, CEO Oscar Munoz issued his most contrite apology yet as details emerged about the man seen on cellphone videos recorded by other passengers at O'Hare Airport.  Munoz latest statement described the removal as "truly horrific," and plans a full review of policies.  Whether his PR or legal department, or both, caused the about face, one can only speculate.  But it stands to reason at there's more to come on this one.  Tony takes a look.
