Australian carrier Qantas Airways will use Airbus A330 aircraft on all of its weekday Sydney-Perth and Melbourne-Perth services from May 2013.
The airline made the announcement after it received a new A330-200, the ninth of the type used on its domestic routes.
"One of Qantas's key strengths in the domestic market is our widebody aircraft, which are very popular with our customers," says Qantas domestic chief executive Lyell Strambi.
Qantas adds that it has 30 widebody aircraft deployed on its domestic routes, including A330s and Boeing 767s.
Strambi says the carrier is progressing with the refurbishment of its 767 fleet and it will operate 16 of the type with new interiors and iPad entertainment systems to each seat by March 2013.
"These aircraft look and feel like new and we expect these changes to be very popular with our customers," he adds.
Qantas operates around 100 services with more than 26,000 seats from Perth to Sydney and Melbourne weekly. Innovata Schedules show that it competes with Virgin Australia and Jetstar on the route.
