Continental Airlines, originally called Varney Speed Lines, began flying in the southwestern U.S. in 1934. It was renamed Continental Airlines in 1937, and in the 1960s, it expanded U.S. operations with the addition of jet planes. In 2011, Continental debuted the first eco-friendly bio-fueled flight.

In November 2011, Continental was acquired by United Airlines. In March 2012, the two carriers merged systems, combining the United name with the Continental logo. Both carriers experienced losses during the recession. By joining forces, they hope to save more than $1 billion annually.

Together with United, Continental Airlines now flies to more than 1,000 destinations worldwide. Headquartered in Chicago with hubs in Denver, Washington, D.C., Los Angeles and San Francisco, the airline now offers flights to more U.S. destinations than any other carrier. Continental Airlines merged passenger service, frequent flier and online systems with United Airlines in March, 2012. Visit United’s airline guide for more information.
