Aero K, the South Korean low-cost carrier based at Cheongju International Airport, is running a promotion on its Hiroshima–Cheongju route. A promo code offering up to 30% off round-trip fares is available from August 3 through August 31, 2026. With few direct options linking regional Japan to central Korea, the sale is a good chance to fly at below-usual prices, especially for travellers planning an autumn holiday or a foliage-season trip.
Sale Overview
The discount applies to round-trip itineraries on the Hiroshima–Cheongju route. Entering the promo code HIJCJJ at booking reduces the round-trip fare by up to 30%. The booking window runs from August 3 to August 31, with travel between August 6 and October 24.
- Route: Hiroshima–Cheongju (round trip only)
- Promo code: HIJCJJ
- Discount: Up to 30% off round-trip fares
- Booking period: August 3–31, 2026
- Travel period: August 6–October 24, 2026 (some dates excluded)
- Eligible fare: Basic Lite
- Payment currency: Japanese yen only
- Included: 15kg checked baggage allowance
Round-Trip Basic Lite Fares Only
The promo code works only on round-trip bookings in the Basic Lite fare class. One-way bookings and higher fare types are not eligible, so check the fare type carefully on the booking screen. Payment must also be settled in Japanese yen; selecting Korean won or another currency will prevent the code from applying. Travellers booking from Japan should switch the site currency to yen before starting.
Surcharges and Taxes Are Not Discounted
The discount applies to the base airfare only. Fuel surcharges, airport fees and other taxes are excluded, which means the effective discount on the final total is usually less than 30%. Review the displayed total and its breakdown before deciding whether the deal works for your itinerary.
15kg Checked Baggage Included
Entry-level LCC fares normally charge extra for checked bags, but this promotion includes a 15kg checked baggage allowance. For anyone planning to shop in Korea or stay several days, being able to check a bag at no extra cost adds real value compared with buying baggage separately.
Watch the Travel Dates
Travel is valid from August 6 to October 24, 2026, but certain dates are excluded, and peak periods such as the Obon holidays and long weekends may fall outside the offer. If your preferred date does not price down, try shifting the search a day or two either way. Discounted seats are limited, so book early once your plans are set.
About Cheongju and the Route
Cheongju International Airport sits in North Chungcheong Province, roughly 120km south of Seoul and close to Daejeon and Sejong. Aero K is based there and operates services to Japan and Southeast Asia. Express buses and trains connect Cheongju with the Seoul area, offering an alternative to the busier Incheon and Gimpo gateways. Hot springs and historic sites in North Chungcheong, plus Daejeon’s food scene, make it easy to build an itinerary around regional Korea. For residents of Japan’s Chugoku region, flying nonstop from their local airport is a major convenience.
