By Plane

In Vietnam, there are four international airports in total. If you want a direct flight, e. g. from the U.S. or Europe to Vietnam, you can either fly to HCMC (with the biggest airport, the Tan Son Nhat International Airport) or to Hanoi (with the second biggest one, the Nội Bài International Airport).

Alternatively, you can take a flight to China, Laos, Cambodia, Thailand, South Korea, Japan or Singapore, and get a connecting flight to Vietnam:

Da Nang has an International Airport (flights from/to Seoul/South Korea, Bangkok/Thailand, Singapore).

Can Tho Airport in South Vietnam provides international service, too (flights from/to Bangkok/Thailand, Tokyo/Japan, Phnom Penh/Cambodia).

Phu Quoc Island now has its own International Airport.

If you buy a ticket for a flight to Vietnam in a nearby country, you might get it for half the price of a Vietnam Airlines’ flight. However, during holidays it will be hard to get a reservation. Especially during Tet you should make reservations in advance. You can also travel into Vietnam overland or on the waterway from one of the adjacent countries.
