Continental Airlines (simply known as Continental) was a trunk carrier, a major, international airline in the United States that operated from 1934 until it merged with United Airlines in 2012. It had ownership interests and brand partnerships with several carriers.
Continental started out as one of the smaller carriers in the United States, known for its limited operations under the regulated era that provided very fine, almost fancy, service against the larger majors in important point-to-point markets, the largest of which was Chicago/Los Angeles. However, deregulation in 1978 changed the competitive landscape and realities, as noted by Smithsonian Airline Historian R. E. G. Davies, "Unfortunately, the policies that had been successful for more than forty years under [Robert] Six's cavalier style of management were suddenly laid bare as the cold winds of airline deregulation changed all the rules—specifically, the balance between revenues and expenditures."
