American Airlines was the first domestic airline to fly its own jets, on January 25, 1959.[citation needed] TWA started domestic 707-131 flights in March and Continental Airlines started 707-124 flights in June; airlines that had ordered only the DC-8, such as United, Delta, and Eastern, were left without jets until September and lost market share on transcontinental flights.[citation needed] Qantas was the first non-US airline to use the 707s, starting in 1959.[6][7]
