Thai budget airline Nok Air will start flights to Hanoi from Bangkok in November.
Nok Air will offer two flights a day using Boeing 737-400s and Boeing 737-800s, said Vo Huy Cuong of Vietnam's Civil Aviation Administration.
Several budget airlines - including Singapore's Tiger Airways, Thai AirAsia and Malaysian AirAsia - have begun flying to Vietnam the last couple years to help meet surging travel demand in the booming Southeast Asian nation.
Cuong said Vietnam air traffic has grown 14-18 percent a year in recent years. Currently, there are 35 foreign airlines operating in Vietnam.
Nok Air currently operates one other international route (Bangkok to Bangalore). The airline plans to add several other news international destinations next year.
