A little history,
In 1925, Western Air Express was formed to deliver a new service, air mail, to the West Coast. Service began in 1926, and passenger service soon followed. The company was based in Los Angeles and operated a run between LA and Salt Lake City. In 1942, the company’s name was changed to Western Air Lines, and later Western Airlines. The airline’s hubs were Los Angeles, Salt Lake City and Denver. Their motto was “The only way to fly”.
In 1987, Western merged with Delta Air Lines. Ever since, Salt Lake City has been a major hub for Delta.
