How to Find Cheap Flights to Vietnam (2026)
Quick answer
To fly to Vietnam for less, be flexible on dates and travel in the shoulder seasons (around March–May and September–November), compare the whole market rather than one airline, and consider a one-stop routing through a major hub, which is usually cheaper than a direct flight. Booking roughly two to six months ahead and using a price alert helps you catch the dips instead of guessing.

When is Vietnam cheapest to fly to?
Vietnam spans several climate zones, so there is no single "off-season," but demand — and therefore fares — tends to peak around the December to February window, covering both the northern-hemisphere winter holidays and, most importantly, Tet (Vietnamese New Year), when the whole country travels. Flying in the shoulder months usually means lower prices and thinner crowds.
| Period | Typical demand | Fare tendency |
|---|---|---|
| Dec–Feb (incl. Tet) | Peak | Highest |
| Mar–May | Shoulder | Often lower |
| Jun–Aug | Mixed (summer) | Variable |
| Sep–Nov | Shoulder | Often lower |
Because Tet shifts with the lunar calendar, its exact dates move each year — check when it falls before you lock in winter travel, as fares spike sharply around it.
Which airport should you fly into?
Vietnam's two main international gateways are Ho Chi Minh City (Tan Son Nhat, SGN) in the south and Hanoi (Noi Bai, HAN) in the north; Da Nang (DAD) in the centre also takes some international flights. If your trip runs the length of the country, an open-jaw ticket — flying into one city and home from the other — avoids doubling back and can cost little more than a return.
Smart ways to lower the fare
- Compare the whole market. A metasearch like ScanFlyGo checks many airlines and agencies at once, so you see the genuine cheapest option rather than one carrier's shortlist.
- Stay flexible on dates. Shifting your departure by a day or two, or flying midweek, can move the price noticeably.
- Accept one stop. Non-stops from Europe or North America are limited and pricey; a single connection through a big hub is usually cheaper.
- Set a price alert. Let the route be watched for you and buy when it drops.
- Price the all-in cost. On long-haul, checked bags are often included, but confirm — and add any seat or meal fees before comparing.
Getting around once you arrive
Vietnam is long and thin, and domestic flights between Hanoi, Da Nang and Ho Chi Minh City are frequent and often inexpensive when booked ahead. If you would rather travel overland, the train and long-distance buses are budget-friendly alternatives. Building a couple of internal flights into your plan can save days of travel time on a two- or three-week trip.
Before you book: the practical checklist
Check your passport has at least six months' validity and confirm the current entry requirements for your nationality well ahead of travel, as visa and e-visa rules can change. Consider travel insurance that covers medical care and trip disruption, and note that Vietnam's weather varies dramatically by region and season — the north can be cool and misty while the south stays hot. None of this changes your fare, but it saves nasty surprises at the airport.
Frequently asked questions
What is the cheapest month to fly to Vietnam?
The shoulder months, roughly March–May and September–November, are often cheaper than the December–February peak that includes Tet. Stay flexible and use a price alert.
Hanoi or Ho Chi Minh City?
Fly into whichever is cheaper or better placed for your route. An open-jaw ticket into one and out of the other avoids backtracking.
How far ahead should I book?
Around two to six months for most long-haul travellers, and earlier for peak season. Compare broadly and buy when the fare fits.
Are one-stop flights cheaper?
Usually yes — a single connection through a major hub tends to beat a direct flight on price. Weigh the saving against the longer journey.
The bottom line
Cheap flights to Vietnam come from flexibility and comparison: travel in the shoulder seasons, avoid the Tet spike, consider an open-jaw or one-stop routing, and let a price alert catch the dip. Start a live search on ScanFlyGo, browse popular routes for current fares, and once you are booked you can track your flight live on departure day.
