Looking for an affordable, exciting summer trip in 2025? Vietnam is emerging as one of Southeast Asia’s top trending destinations—famous for its street food, world-class beaches, vibrant cities, and rich culture.

But how do you find the best-value flights? Which budget airlines (LCCs) actually fly to Vietnam? What’s the smartest way to stay connected?
This guide provides international travelers with up-to-date info, price examples, and practical booking tips for a stress-free, wallet-friendly Vietnam journey.

1. Why Vietnam Flights Are Getting Cheaper in 2025

  • More routes opening: Major carriers and new budget airlines now connect Vietnam to the world’s biggest hubs in Europe, North America, Australia, and all over Asia.
  • Visa flexibility: Vietnam is simplifying e-visas and visa-on-arrival for more countries in 2025.
  • High demand: Summer break, remote work trends, and backpacker popularity are increasing competition—meaning better deals for you!

4. How to Find the Cheapest Airfare

  • Book in advance: 3–6 months ahead is usually best for long-haul routes. For last-minute planners, monitor prices with fare alerts.
  • Travel mid-week: Tuesday, Wednesday, and Thursday departures are often cheaper.
  • Compare everywhere:
  • Avoid peak holidays: Vietnam’s own holidays (Tet, national days) and global August “summer rush” are most expensive.
  • Combine LCCs with mainline carriers: Try booking separate tickets (USA → Tokyo/Seoul + LCC to Vietnam).

5. What to Check With LCC Tickets

  • Extra charges:
    Checked luggage, seat selection, in-flight meals, and date changes are often extra.
  • Airport locations:
    Some LCCs use secondary airports—check your arrival city carefully!
  • Delays/Connections:
    Leave generous time if connecting between separate tickets; LCCs rarely rebook for missed transfers.
  • Insurance:
    Consider travel disruption insurance, especially for long or complex itineraries.

6. Exclusive Promotions & Discount Codes (Summer 2025)

  • VietJet Air: Frequent “zero-fare” campaigns if booked on their site.
  • Scoot & AirAsia: Up to 50% off selected routes via email promos.
  • Aggregators: Trip.com, Kiwi, and Skyscanner list occasional app-exclusive fares.
