Continental Micronesia, Inc. (CMI) was a company which was a wholly owned subsidiary of Continental Airlines. It operated daily flights to Honolulu, Hawaii, as well as international services to Asia, Micronesia and Australia from its base of operations at Antonio B. Won Pat International Airport on Guam, a U.S. territory in the western Pacific Ocean. During its final years, the airline, a Delaware corporation, was headquartered in the old terminal building at Won Pat International Airport and in Tamuning, Guam.

On December 22, 2010, as a result of the Continental-United Airlines merger, the FAA approved the combination of Continental Micronesia's air carrier operations with Continental's under the single Part 121 operating certificate of Continental; although Continental Micronesia remained as a corporation, all flights were then operated directly by Continental Airlines. This step was intended to simplify future integration steps between Continental and United. The callsign, ICAO and IATA codes were changed to reflect the new operating certificate.

As of 2012 the Continental Micronesia employee group, now a subset of United Continental Holdings, had 1,222 employees.

Continental Micronesia flights used the regular Continental "CO" code on ticketing systems and for frequent-flyer benefit accounting, but used its ICAO code "CMI" and callsign "Air Mike" with air traffic control authorities. In airport terminals, Continental Micronesia flights were listed separately (from Continental) with its IATA code "CS". During the final decade, three airports had both "Air Mike" and mainline Continental present: Hong Kong, Tokyo and Honolulu.
