AirAsia Group Thailand sale starts at 21,670 yen one way
Thai AirAsia and Thai AirAsia X are running a promotion for Japan–Thailand routes called “Saiko no Tabi e Thailand” (Best Trip to Thailand) from August 31 to September 6, 2026. One-way fares start at a total of 21,670 yen including fuel surcharges and taxes, and the travel period stretches into the busy autumn and year-end season.
Eligible routes and lowest one-way fares
The sale covers routes linking Bangkok/Don Mueang with four Japanese airports: Sapporo/Chitose, Tokyo/Narita, Nagoya/Chubu and Osaka/Kansai. Published one-way minimum fares are listed below, all shown as total prices including fuel surcharges and taxes.
- Sapporo/Chitose – Bangkok/Don Mueang: 28,615 yen
- Tokyo/Narita – Bangkok/Don Mueang: 23,791 yen
- Nagoya/Chubu – Bangkok/Don Mueang: 29,209 yen
The lowest price across the campaign is 21,670 yen one way in total, which appears to apply to Osaka/Kansai departures. Actual fares vary by travel date, booking timing and seat availability, so it is best to compare day-by-day pricing in the calendar view on the official website.
Phuket, Chiang Mai and other resort routes included
Beyond Bangkok/Don Mueang, sale fares are also available to Phuket, Krabi, Chiang Mai and Chiang Rai. Using the Fly-Thru connecting service via Bangkok, travellers can continue straight through to southern beach resorts or the northern old capital, making it easy to build an itinerary that combines coastline and mountains.
Booking and travel periods
- Booking (sales) period: August 31 – September 6, 2026
- Travel period: September 7 – December 31, 2026
Note that certain blackout dates apply within the travel period. Exclusions and higher fare bands become more common closer to long weekends and the year-end holidays, so travellers with flexible schedules should focus their searches on weekday departures. Shifting an outbound or return date by just one day can change the total by several thousand yen.
Value Pack add-on up to 30% off
During the campaign, the Value Pack option bundling checked baggage, advance seat selection and an in-flight meal is discounted by up to 30%. Buying these services individually on a low-cost carrier tends to be expensive, so bundling them helps keep the overall trip cost down.
Importantly, the discount applies only when the add-on is purchased at the time of booking the ticket. Adding it after the reservation is completed means paying the standard price. Travellers planning to check bags or wanting a meal on board should select it on the booking screen. Flights from Narita and Kansai run roughly six hours, so locking in a meal and seat assignment makes a noticeable difference in comfort.
Thai AirAsia vs Thai AirAsia X
Japan–Bangkok services are operated by Thai AirAsia X, the medium- to long-haul arm using Airbus A330s, and Thai AirAsia, the short- to medium-haul arm using A320s and A321s, depending on the route. Neither includes checked baggage or meals in the base fare, following the standard low-cost model of paying only for what you need, which is exactly where the Value Pack discount adds value.
Keep in mind that Don Mueang is a separate airport from Suvarnabhumi. Access to central Bangkok is available by airport bus, rail or taxi, taking roughly 40 minutes to an hour. If you are connecting to another airline operating from Suvarnabhumi, allow ample time for the transfer between airports.
Points to check before booking
- Advertised fares are the lowest one-way prices and seat availability is limited
- Fuel surcharges and taxes are included, but payment handling fees may apply separately
- Checked baggage is not included; carry-on items are subject to weight and size limits
- Blackout dates exist within the travel period, so the lowest fare is not offered every day
- Change and refund conditions differ depending on the fare type

Summary
A total of 21,670 yen one way is a genuinely accessible price point for Japan–Bangkok travel. The sales window runs only one week until September 6, and the cheapest seats on popular dates are likely to sell out early. With the travel period running from September 7 through December 31, anyone planning an autumn long weekend or a year-end trip should narrow down two or three candidate date patterns first, then search.
