Marked increases in domestic flights around September 2, interesting opportunities on international routes, great promotions from airlines, and booking advice to save money: BestPrice Travel provides a comprehensive overview of airfare trends for September and through the end of 2025. Between peaks of demand for Hanoi, Da Nang, or Phu Quoc and attractive rates to Bangkok, Tokyo, or Seoul, here’s what you need to know to plan your trips at the right time.
Around the national holiday of September 2, Vietnamese airports are operating at full capacity, and the prices of air tickets adjust upwards on the most demanded routes. Round trips in economy class between Ho Chi Minh City and Hanoi currently range from about 4.5 to 7.5 million VND, well above the average observed in September around 3 million VND. Routes to the beaches, such as Hanoi–Da Nang or Ho Chi Minh City–Phu Quoc, follow the same trajectory, boosted by the influx of vacationers and highly sought-after slots.
Meanwhile, the international segment shows multiple “good deals.” A round trip Ho Chi Minh City–Bangkok around September 2 starts at approximately 4 million VND, which sometimes places it below domestic fares to Hanoi or Phu Quoc. On medium and long-haul flights, competitive starting points appear toward hubs like Tokyo or Seoul, supported by promotional campaigns from airlines.

The increase in domestic fares is explained by a concentrated demand on a few holidays and a capacity that cannot always instantly adjust. The routes Ho Chi Minh City ↔ Hanoi, Hanoi ↔ Da Nang, and Ho Chi Minh City ↔ Phu Quoc rank among the most sought-after, leading to a pressure on prices and busier airports as September 2 approaches. The “reference price lists” published by industry players confirm this short-term trend, typical of peak periods.
To mitigate the impact of these increases, BestPrice recommends booking 2 to 6 weeks in advance for domestic tickets, favoring flights early in the morning or late at night, and aiming for the middle of the week rather than weekends. These less popular choices often allow for significantly lighter fares and help avoid the densest queues.

On the international front, several routes stand out due to enhanced promotions at the end of summer. Aside from the very affordable Bangkok in early September, the Ho Chi Minh City–Tokyo and Hanoi–Seoul routes show competitive starting prices. Notably, a vast campaign by Vietnam Airlines: domestic tickets valid for travel from the end of August until December 31, 2025, and international tickets valid from September 1, 2025 to May 31, 2026. This generous window opens the way for attractive departure points to Japan, South Korea, or Thailand.

According to Mr. Nguyen Van Dat, CEO of BestPrice Travel, the best practice is to anticipate bookings. For the international, the October–November period is seen as ideal, just before the high season of Christmas and New Year, when fares tighten. For domestic travel, the 2 to 6 weeks window before departure remains the most relevant to avoid last minute surcharges.
To support travelers, BestPrice runs the “0 VND Ticket Hunt every Friday,” offering the chance to snag unbeatable fares, sometimes advertised without taxes or fees. Several success cases have been reported: round trips Hanoi–Ho Chi Minh City around 700,000 VND, or Ho Chi Minh City–Da Nang near 715,000 VND. In addition, preferring morning or evening departures, aiming for mid-week and regularly monitoring airline announcements remains a winning strategy.

Beyond key routes in Asia, the year 2025 is looking mixed, with sporadic opportunities in long-haul leisure markets. For a city break, watch for deals to the United States and explore New York at a low price when airlines launch promotional campaigns over the North Atlantic.
Need to escape to the Mediterranean? A last-minute deal in Greece can lower the overall budget, especially if you synchronize your purchase with price drops on regional flights. In the Caribbean, refining the choice between Martinique and Guadeloupe depending on seasonality can also optimize the cost-benefit ratio of the trip.
