In the midst of World War II Connellan consolidated his air services, which had grown viable and included more routes, and registered Connellan Airways on 23 July 1943. In June 1944 Connellan became a founding member of the Northern Territory Development League. In the post war years Connellan Airways grew, acquiring new routes and equipment. In February 1951 it became a limited company, with many of the shares held by station people and staff. In 1963 Connellan Airways became a regular public transport (RPT) operator. In 1970 the name was changed to Connair. Connair faced financial difficulty in the 1970s and was sold to East-West Airlines on 14 March 1980. It went into liquidation shortly after.
