Royale operated scheduled passenger flights in Louisiana, Texas, Mississippi, Tennessee and Florida from 1962 to 1989. It flew mainly turboprop aircraft such as the Embraer EMB-110 Bandeirante, Beechcraft Model 99, Short 330 and Grumman Gulfstream G-I with the latter being a regional airliner version of Grumman's successful propjet business aircraft. Royale also flew two Douglas DC-9-14 jetliners on services from Houston primarily to Brownsville, Texas (BRO) on behalf of Continental Airlines. For a short period between 1985 and 1986 Royale operated de Havilland Canada DHC-6 Twin Otter aircraft acquired from Metro Airlines which had moved its operations to the Dallas-Fort Worth Metroplex in Texas and also to Atlanta, Georgia. These Twin Otter STOL (Short Take Off and Landing) turboprop aircraft were primarily utilized to shuttle passengers between the Clear Lake City STOLport, which was located near the NASA Johnson Space Center, and Houston Intercontinental Airport (IAH, now Houston George R. Bush Intercontinental Airport).
Royale also operated as a Continental Express air carrier via a code sharing agreement with Continental Airlines and provided passenger feed at Continental's Houston hub (IAH) during the final years of operation prior to its bankruptcy Chapter 11 filing on September 9, 1987.
