Malaysian budget-airline Air Asia X hints it is considering dropping its Kuala Lumpur - Christchurch route.
The airline is reviewing all its long-haul networks because of increasing fuel prices and airport charges. Earlier this year it announced cuts to flights to Europe and India.
The company has told the New Strait Times newspaper the airline's most effective operations are seven and eight hour flights, and some routes are no longer viable because charges and costs have been raised in all the overseas airports it flies to.
The airline began the 11- hour flight to Christchurch last year and operates the service four times per week.
Air Asia X recently announced its pulling out of routes to Darwin, in Australia - a service it began in 2010.
