Budget carrier AirAsia is offering a 20 percent discount on all fares for travel between March 23 and May 31 as part of its Lunar New Year celebrations.
The discount will be available for online bookings made between February 18 and 21.
The airline flies to more than 70 destinations in Southeast Asian countries, India, China, Britain, and Australia.
Malaysia-based AirAsia was the first budget carrier in Asia and flies from Hanoi and Ho Chi Minh City to Malaysia, Thailand, and Indonesia.
Last week it announced it has bought a 30 percent stake in Vietnamese private carrier VietJet Aviation Joint Stock Co. to establish a Vietnam-based no-frills airline called VietJet AirAsia.
The carrier is scheduled to begin operations in May on both domestic and international routes.
