How to find cheap flights to Vietnam? 10 Ultimate Tips

07/06/2025 | Onward Ticket | 0 comments

Vietnam is a country where ancient traditions are combined with vibrant, modern energy. From the stunning limestone karsts of Ha Long Bay to the bustling markets of Ho Chi Minh City, a trip to Vietnam is an unforgettable experience. But before you can taste your first bowl of authentic pho, you have to book your flight, and that can often feel like the most expensive part of the journey.

The good news? It doesn’t have to be. With a few key strategies with Onward Free, you can significantly reduce the cost of your flight, freeing up more of your budget for the adventure itself. Here are 9 proven tips for finding cheap flights to Vietnam.

Tip 1: Be flexible with your travel dates 

Being flexible with your travel dates is the number one rule for saving money on flights. Prices can vary dramatically depending on the day, week, or month you choose to travel. Flying during the “shoulder seasons” (May-June and September-November) can offer a fantastic mix of good weather and lower prices compared to the peak season (December-April). If you can, avoid traveling around major holidays like Christmas and New Year’s, especially the Vietnamese Tet holiday (late January/early February), when prices are at their highest. This flexibility is key to finding cheap flights to Vietnam.

Tip 2: Be Flexible with Airports

Vietnam is home to three major international airports: Noi Bai International Airport (HAN) in Hanoi, Da Nang International Airport (DAD) in the central region, and Tan Son Nhat International Airport (SGN) in Ho Chi Minh City. When you search for flights, don’t just check the prices for one. Compare the costs of flying into all three. You might find that securing cheap flights to Vietnam is easier by flying into one city and then taking a budget-friendly domestic flight or train to your final destination.

Tip 3: Book in the “Sweet Spot”

Flight prices follow a predictable pattern. They start high, dip to their lowest point, and then climb steeply as the departure date approaches. For long-haul international flights to Vietnam, this “sweet spot” is typically 2 to 6 months before your travel date. Booking too early or leaving it to the last minute will almost always cost you more when hunting for cheap flights to Vietnam.

Tip 4: Get cheap flights to Vietnam with red-eye flights

If you don’t mind traveling at odd hours, red-eye flights (which depart late at night and arrive early in the morning) can be a goldmine for savings. These less-desirable flight times are often much cheaper because fewer people want to fly them. It’s a small inconvenience that can lead to big savings, and as a bonus, you might even save on a night’s accommodation.

Tip 5: Travel light to save on baggage fees

In the era of budget airlines, baggage fees can quickly turn a cheap flight into an expensive one. Whenever possible, try to travel with only a carry-on. If you must check a bag, be sure to check the airline’s baggage allowance and fees beforehand. It’s almost always cheaper to pay for your baggage online in advance than to pay for it at the airport check-in counter.

Tip 6: Use the Best Flight Search Engines

Don’t search for flights on just one airline’s website. Use a flight aggregator to compare prices from hundreds of sources at once. The best and most popular tools to find cheap flights to Vietnam include:

  • Google Flights: Excellent for its simple interface and powerful calendar view that shows you the cheapest dates to fly.
  • Skyscanner: A robust search engine that sometimes includes smaller budget airlines that other search engines miss.
  • Momondo: Great for its intuitive design and ability to find unique flight combinations.

Tip 7: Go Incognito and Set Fare Alerts

To avoid price hikes based on your search history, always use an incognito or private browsing window when looking for flights. Once you’ve found a route you’re interested in, don’t just keep checking it manually. Set a fare alert on Google Flights or Skyscanner. You’ll get an automatic email notification when the price drops, allowing you to book at the perfect moment.

Tip 8: Consider flights with layovers

Direct flights are convenient, but that convenience almost always comes at a premium. Being willing to accept a flight with one or two layovers can dramatically reduce the cost of your ticket. While it extends your travel time, the savings can often be worth hundreds of dollars, money that’s better spent on your actual trip. It’s a classic strategy for getting cheap flights to Vietnam.

Tip 9: Get cheap flights to Vietnam with One-Way Tickets

This is an advanced strategy that can unlock huge savings, but it requires one crucial piece of preparation to work without a hitch.

The One-Way Ticket Advantage

Instead of booking a standard round-trip ticket, look at the price of booking two separate one-way tickets. This allows you to mix and match airlines, often combining a major carrier for one leg and a budget airline for the other. The result can be a total price that’s much lower than any single round-trip fare.

The Onward Ticket Solution

Here is the critical catch: When you travel on a one-way ticket, most airlines and immigration authorities (including Vietnam’s) will require you to show proof of onward travel. This is to prove you don’t intend to stay in the country illegally. Without it, you can be denied boarding at your departure airport, causing a massive headache and potentially ruining your trip.
