All Australian Virgin-branded airlines (With the exception of Virgin Australia Regional Airlines) originally operated under the IATA Code; DJ. This flight code has since ceased and now each airline division operate under differing IATA and ICAO codes; Virgin Australia - VA/VOZ, Virgin Australia International - VA/VAU, Virgin Australia Regional Airlines (Previously Skywest Airlines) - XR/OZW. These airlines have now been differentiated within the Airline Risk Calculator and all feature their individual risk ratings.
Since December 2011, all operations of the former airlines Virgin Blue, Pacific Blue, and VAustralia were amalgamated under the 'Virgin Australia' branding and livery. Mainline carrier Virgin Australia developed a specific branch for most of its international destinations previously served by VAustralia, referred to as Virgin Australia International. These two operational divisions are considered separate as the two airlines each have an allocated fleet and specific destinations it serves, despite operating under the IATA code of VA.
Virgin Australia Regional Airlines (Formerly known as Skywest Airlines) is the small regional branch Virgin Australia. The airline was previously named "Skywest Airlines" and commenced operations in 1980. In 2011, Skywest committed to a 10 year alliance with fellow Australian carrier; Virgin Australia. In 2013, Virgin Australia purchased the ownership rights to Skywest Airlines and subsequently renamed it to "Virgin Australia Regional Airlines (VARA)". As a result of this acquisition, Skywest became a part of the Australian Virgin brand, however continued to operate under its own Air Operator Certificate (AOC) and retained its existing management structure. Virgin Australia and Virgin Australia International are categorised as low risk airlines with scores of 7.68 and 7.25 respectively. VARA however, is classified as mid-risk due to its limited operational capability and its aging fleet of aircraft.
