Overview of the HK Express JCB Card Campaign

HK Express, the Hong Kong-based low-cost carrier, is running a ‘JCB Card Campaign’ from November 2 to November 15, 2026. Pay with a JCB card issued in Japan and you get a discount on the fare for flights to Hong Kong. The discount depends on where you depart from. Fares from Tokyo, Osaka, Nagoya and Fukuoka are 15% off. Fares from Sendai, Komatsu, Takamatsu, Hiroshima and Okinawa are 10% off. To get the discount, you must enter the promo code UOJCB when booking.

The campaign ends on November 15, so as of this article’s publication on November 9, about a week remains. If you are thinking about a trip to Hong Kong between winter and late March, decide on your dates and book early.

Eligible Routes and Discount Rates

The offer covers flights to Hong Kong from 10 airports in Japan. The discount comes in two tiers, depending on the departure airport.

Routes with 15% Off the Fare

Tokyo/Haneda → Hong Kong
Tokyo/Narita → Hong Kong
Osaka/Kansai → Hong Kong
Nagoya/Chubu → Hong Kong
Fukuoka → Hong Kong

Flights from the major airports in the Tokyo area, Kansai, Chubu and Kyushu get the top discount of 15%. Both Haneda and Narita are included for Tokyo. You can choose whichever airport is easier to reach or has a better departure time.

Routes with 10% Off the Fare

Sendai → Hong Kong
Komatsu → Hong Kong
Takamatsu → Hong Kong
Hiroshima → Hong Kong
Okinawa/Naha → Hong Kong

Departures from airports in Tohoku, Hokuriku, Shikoku, the Chugoku region and Okinawa get 10% off. You can book a discounted flight to Hong Kong from your nearest airport without traveling to a big-city hub. That is a real advantage for travelers outside the major metropolitan areas.

About Prices

No specific fare amounts have been announced for this campaign, only the discount rates (10% to 15%). Actual fares vary by travel date and flight. Enter your preferred dates on the official website to check them.

What the Discount Covers and What It Doesn’t

The discount applies only to the base fare. The following charges are not discounted:

Fuel surcharges
Taxes and fees
Checked baggage
Seat selection
In-flight meals
Other add-on services

As a low-cost carrier, HK Express sells baggage, seat selection and meals as optional extras. This means your total payment will not be a full 15% lower. For example, if the base fare is 20,000 yen, 15% off saves 3,000 yen. Fuel surcharges, taxes and add-on services are still charged at full price (this is only an illustrative calculation, not an actual fare).

Travel Period and Peak Blackout Dates

The eligible travel period runs from November 23, 2026 to March 25, 2027, about four months that cover most of the winter season in Hong Kong.

However, some peak periods are excluded. The travel window includes the year-end and New Year holidays and the Lunar New Year. If you plan to travel during these times, make sure your dates are not blacked out before you book. Please check the official website for the specific excluded dates.

How to Book

Step 1: Go to the HK Express official website (https://www.hkexpress.com/ja)
Step 2: Select an eligible departure airport, Hong Kong as your destination, and your travel date (between November 23, 2026 and March 25, 2027)
Step 3: Enter the promo code UOJCB
Step 4: Check that the discount has been applied to the fare
Step 5: Pay with a JCB card issued in Japan

The discount will not apply unless you enter the code, so be careful not to skip it or mistype it.
