I have a time frame of 45 min. from projected landing time in terminal F to projected take off time in terminal A. Will this be enough time to take the shuttle bus all the way around to terminal A? I will have a carry on only to worry about. The flight I am trying to plan for is to LAX. I don't know where to find specific details about the on time statuses for American Airlines at PHL. I am just worried about making the connector to LA.
