When is the best time to book cheap flights to Vietnam?

For those traveling on a budget, the best times to fly to Vietnam in 2025 are March and April, as well as September and October. These months, marking the transition into and out of peak tourist season, often offer the most competitive deals. Flights during these periods may be priced 5-10% lower, and in some cases, fares can drop by up to 30% compared to peak season rates.

Throughout the year, there are still opportunities to find reasonable airfare to Vietnam, but prices typically soar during the summer months and around Tet Holiday, Vietnam's Lunar New Year, which generally occurs between late January and early February.

Summer in Vietnam spans from late May to late August, a popular time filled with various tourism activities that attract a wide array of travelers. During this peak season, securing desired flights becomes more challenging, and ticket prices tend to be significantly higher than during off-peak months.

A similar pattern occurs during Christmas and Tet Holiday, albeit to a greater extent. The influx of not only tourists but also overseas Vietnamese returning home for family reunions leads to increased demand and overbooking on many international flights to Vietnam.

On the other hand, traveling between September and November or February and April can be particularly advantageous. Airlines often launch seasonal promotions and discounts during these months, incentivizing travel and making it more affordable for visitors.
