The travel period is fairly long, from October 21 to January 31, 2027, so you can plan anything from an autumn weekend getaway to a winter break or a trip after New Year. This article covers the sale details, the eligible routes, an estimate of the total cost including the fuel surcharge, and key points to check before booking.

- Tokyo Haneda – Hong Kong

- Osaka Kansai – Hong Kong
- Fukuoka – Hong Kong
- Okinawa Naha – Hong Kong
In the Tokyo area, both Haneda and Narita are included. Compare access from your home and the fares on your preferred dates. Sale fares are listed as starting prices, so prices may vary by date and flight even on the same route. We recommend searching several dates to compare.
Fare Types and Estimated Total Cost
Ultra Lite: From ¥4,000 One-Way
This is the cheapest fare type in the sale and suits travelers who want to keep airfare as low as possible. However, included services differ by fare type. Be sure to check conditions such as checked baggage and seat selection on the booking screen.
Lite: From ¥5,000 One-Way
Comparing the lowest fares, the difference from Ultra Lite is ¥1,000 one-way. Consider how much luggage you have and your itinerary, and choose the fare type that best fits your travel style.
Estimated Cost Including Fuel Surcharge
In addition to the sale fare, a fuel surcharge of ¥9,900 one-way applies, and taxes are charged separately. Based on the lowest fares, the estimated payment is as follows (excluding taxes):
- Ultra Lite: ¥4,000 + ¥9,900 fuel surcharge = from ¥13,900 one-way
- Lite: ¥5,000 + ¥9,900 fuel surcharge = from ¥14,900 one-way
- If you get the lowest Ultra Lite fare on both the outbound and return flights: from ¥27,800 round trip
The fuel surcharge is higher than the base fare itself. If you budget only on the headline ¥4,000, you will end up paying much more than expected. When comparing with other airlines or sales, always compare the total including the fuel surcharge and taxes.
Travel Period and Recommended Timing
The travel period runs about three and a half months, from October 21, 2026 to January 31, 2027. However, some periods are excluded. Check whether your preferred dates qualify when booking. On the calendar, the period lines up well with the following holidays:
- Late October–November: Short trips using Culture Day on Tuesday, November 3, or the three-day weekend from Saturday, November 21 to Monday, November 23 (Labor Thanksgiving Day).
- December: Christmas-season trips or travel during the year-end holidays.
- January 2027: Trips after New Year, such as the three-day weekend from Saturday, January 9 to Monday, January 11 (Coming of Age Day).
Long weekends and peak periods such as the New Year holidays may fall within the excluded periods. If your dates are already set, search early to confirm they qualify.
Things to Check Before Booking
- Short booking window: The sale ends on October 7. Check the exact end time on the official website, and book early if you are planning a trip.
