Ornament Valley Airport is a new place in the "Ornament Valley" section of Radiator Springs. It is part of the area that you can drive through (a lot of Ornament Valley, and the other two areas, are blocked off). There is a hanger, that you can drive through from one end to the other, with a conveyor belt above that has only one entrance, and the other end as an exit only. On the other side of the runway, there are more hangers. You can drive down the runway to the end. No planes come to the airport or leave it anytime during the game.
The airport did not return in the next game Cars Race-O-Rama, just like most of the new stuff in Cars Mater-National.
