Both terminals of Oakland International Airport are connected through gates and the post-security areas. Terminal 1 connects From Gate 4, which leads to 1 to 17 and Terminal 2 From Gate 20, which leads to 20 to 32. As mentioned above, passengers can walk between Terminals through the covered pedestrian walkway. There is no Tram system for inter-terminal transportation.
For planes not connecting to the jet bridges of the airport, ramp stairs are used to board and exit planes. Passengers are then transferred to the arrival section of the airport by bus.
