PIT offers on-site parking operated by the Grant Oliver Corporation and patrolled by the Allegheny County Police. Grant Oliver offers usage of a GO FAST Pass account to pay for parking electronically at the airport. Go Fast Pass customers may register their E-Zpass transponders to use with the system, although billing and other aspects of the system are entirely handled by Grant Oliver. There are regular parking shuttles to the Long Term and Extended lots that can be accessed from the Baggage Claim level of the Landside Terminal outside doors six and eight.
