AirAsia X is to shift its London base from Stansted to Gatwick from October 2011.
The budget long-haul carrier currently flies six times a week between Stansted and Kuala Lumpur where flights feed into the Air Asia low-cost network across Southeast Asia.
AirAsia X also operates from Kula Lumpur to Bombay, Delhi, Melbourne, Perth, Christchurch, Wellington and several cities in China.
As the UK’s second-biggest airport, Gatwick will offer AirAsia X greater commercial possibilities.
The carrier has flown from Stansted since its launch in 2008.
AirAsia X is also believed to considering operating from Manchester airport. The carrier also flies from Paris Orly.
