Vietjet will give away 400,000 promotional tickets, starting at zero dong, in a bid to meet passengers' surging demand for travel, the airline said.
As part of the airline's well-known "It is time to Vietjet" promotion, the giveaway will run from January 14 to 16.
The promotion will apply to all Vietjet passengers flying on its international routes to Seoul, Taipei, Singapore, Bangkok and Yangon between February 1 and December 31 (excluding public holidays).
Earlier, Vietjet Air announced to add over 800 flights, starting from January 20 to February 20 to meet travel demand during Lunar New Year 2016.
Major flight routes to be increased include Ho Chi Minh City-Ha Noi (30 return routes a day), Ho Chi Minh City-Da Nang (13 return routes a day), Ho Chi Minh City-Hai Phong (7 return routes a day), and Ho Chi Minh City-Vinh (6 return routes a day).
Vietjet said it was planning faster expansion this year, which would result in further domestic market share gains and a larger international network.
