query: When was CityFlyer Express airline founded?
passage: CityFlyer Express
The management of Air Europe Express quickly started a new airline, Euroworld Airways, and began operations in May 1991 using two Shorts 360 aircraft and staff from the old Air Europe Express. The new carrier also carried on night freight and mail contracts from the defunct airline. The airline soon began flights from Gatwick to Guernsey, Antwerp and Rotterdam, for which two additional Shorts 360s were purchased. At this time, the airline approached several large carriers with a view to establishing a link, but in the event only British Airways was to show any interest, and a code share agreement was struck between the two.

Standard Airlines, later absorbed by American Airlines, remained in business for about 30 months. Frye, as well as being the founder of the company, was also an active pilot of the line. Because of the Great Depression, Frye and his associates sold the airline to Western Air Express in March 1930. Concomitant with the sale, Frye joined Western Air Express on the Board of Directors and as Chief of Operations. Later in 1930, Western Air Express merged with Transcontinental Air Transport in 1930 to form T&WA (TWA). Frye became president of T&WA in 1934 and Richter became Vice President. TWA was known as "The Airline Run by Flyers."
