JAL Express (JEX) was established on April 1, 1997 as a wholly owned domestic subsidiary airline of Japan Airlines (JAL), with initial capital of ¥5.8 million. It operated scheduled passenger services to regional domestic destinations in Japan, as well as some low-demand flights for JAL under wet-lease agreement. It was also considered for services on the domestic trunk and short-haul international routes. On July 1, 1998, JAL Express commenced operations from Osaka to Miyazaki and Kagoshima with two Boeing 737-400s, non-Japanese cockpit crew, and short-term contracted cabin attendants. The airline's cabin attendants, called "Sky Cast", were responsible for cleaning the 150-seat cabin between flights.
