Meant primarily to serve as an airport shuttle, as indicated by the name, it is an extended version of the iconic Checker Marathon.

Standard equipment for 1966 included three-speed manual transmission, power brakes, windshield washer, and a front stabilizer bar.

By 1974, intended to be the last year for the Aerobus as Checker ended production of the station wagons, the power was increased to 160 hp (119 kW), using a four-barrel carb instead of the two-barrel seen in the Marathons.

An artist rendering of a possible Aerobus Ambulance shows that Checker was interested in catering to the medical transport market.
