HK Express Runs a Three-Day Flash Sale
Hong Kong-based low-cost carrier HK Express is holding a limited-time Flash Sale from 11:00 a.m. on August 21, 2026 through August 23. The promotion covers Japan-departing routes linking Tokyo/Haneda, Tokyo/Narita and Osaka/Kansai with Hong Kong, with one-way fares starting from just 3,000 yen. With only three days on the clock, the cheapest seats on popular routes and weekend dates will disappear first, so travelers with fixed plans should book early.
Eligible Routes and One-Way Fares
The Flash Sale applies to the following three Japan-departing routes:
- Tokyo/Haneda – Hong Kong
- Tokyo/Narita – Hong Kong
- Osaka/Kansai – Hong Kong
One-way fares start from 3,000 yen for the entry-level Ultra Lite fare and from 4,000 yen for the higher Lite fare. Note that these figures cover the base fare only. A fuel surcharge of 14,300 yen each way, plus airport charges and other taxes, must be paid separately.
Ultra Lite vs. Lite: What’s the Difference
HK Express offers several fare types that differ by the services included. The Ultra Lite fare is the cheapest option and assumes carry-on baggage only, with checked baggage and seat selection available as paid extras. The Lite fare sits one step above and includes items such as checked baggage. If you are traveling with more luggage or planning to shop in Hong Kong, paying the extra 1,000 yen or so for the Lite fare may actually work out cheaper overall. Compare the add-on baggage fee on the booking screen before deciding.
The Real Total With Surcharges and Taxes
The cost most often overlooked in LCC sales is everything outside the headline fare. With a fuel surcharge of 14,300 yen each way, even a 3,000 yen Ultra Lite ticket works out to roughly 18,000 yen one way once taxes are added, or around 35,000 yen for a round trip. That is still clearly cheaper than typical full-service carrier pricing, making it attractive for spontaneous weekend getaways or short holiday breaks. Always check the total shown on the final confirmation screen before paying.
Travel Period and Blackout Dates
The sale is valid for travel from September 1 through October 31, 2026. However, some blackout dates apply. High-demand periods such as Japan’s Silver Week and the mainland China National Day holiday in early October are likely to be excluded, or to have very limited inventory at the lowest fare levels. Choosing weekday departures and weekday returns significantly improves your chances of securing the cheapest fares.
How to Book
Bookings can be made through the HK Express official website or mobile app. The sale page is available at the link below:

Traffic spikes right after the sale opens can slow the site down, so register and log in ahead of time and have your passport details and payment method ready for a smooth checkout.
A Good Window for Autumn in Hong Kong
September and October bring relief from Hong Kong’s summer humidity, making walking tours and hiking far more comfortable. Whether it’s exploring Central and Tsim Sha Tsui, working through dim sum and local street food, or taking a ferry out to the outlying islands, even a two- or three-night trip can be packed with highlights. Hong Kong also functions as a major connecting hub for Southeast Asia, so it works well as a launch point for a longer journey.
Things to Check Before Booking
- Advertised fares exclude the fuel surcharge (14,300 yen each way) and taxes
- Seats are limited and the lowest fares may sell out quickly
- Blackout dates apply within the travel period
- The Ultra Lite fare does not include checked baggage – estimate add-on costs based on your luggage
- Change and refund conditions vary by fare type, so review the rules before booking
- Confirm passport validity and entry requirements in advance
Summary
HK Express’s Flash Sale runs for three days only, from 11:00 a.m. on August 21 to August 23. Tokyo/Haneda, Tokyo/Narita and Osaka/Kansai to Hong Kong start from 3,000 yen one way, with travel valid from September 1 to October 31. Factor in the fuel surcharge to understand the true total, then start planning that autumn trip to Hong Kong.
