PHX I know what the ticket says, but this OP had a connecting flight on the same airline. Her contract was not just to land in PHilly. It if was and she arrived late and was say late for a wedding, the airline would not comnpensate her. But she had a connection and in your reasoning you do not deal with how the airline will escape liability for the connecting flight leaving without her. They are in breach. Even if for ATC reasons their aircraft arrived late in Philadelphia, it was not ATC control that led them to decide to let the next plane take off without the connecting passengers. That was their decision and it was that, and not the late arrival that caused the problem
