Cheongju International Airport (CJJ) — Airport Guide 2026
From 1 January 2026, every foreign traveller landing in Korea — visa-free or otherwise — must submit a Korea e-Arrival Card online before arrival. That is the one practical change that makes this year’s version of this guide different from last year’s, and it is the thing most people get wrong.

🏢 The Terminal & What CJJ Actually Is
Cheongju handles both domestic and international traffic out of a single building, with the international side on the third floor. The walk from kerb to gate takes minutes rather than corridors, and that compactness is the whole point — it is the quiet, cheaper option for flights from China, Japan, Taiwan and a thin spread of Southeast Asian leisure routes, useful precisely because Incheon is not.
Aero K is headquartered here and runs the most departures, domestic and international. Korean Air, Asiana, Jeju Air, Jin Air and T’way also serve the airport, mostly on the busy Jeju shuttle and a handful of regional international routes. Chinese carriers handle the China routes. Domestic traffic is dominated by Jeju; international service covers China, Japan, Taiwan and seasonal Southeast Asian points including Thailand and Bali.
CJJ is not a transfer hub. The international schedule exists to serve leisure demand on point-to-point routes, not to move connecting passengers. If you are self-transferring — flying in from one city and out to another — you will clear immigration, collect your bag, and re-check it. There is no airside connection between separate international flights.
⚠️ Do not photograph the apron
This is a joint civil-military airport, home to the Republic of Korea Air Force’s 17th Fighter Wing and its F-35A aircraft. The restriction on photographing the apron, military aircraft, and aircraft movements is enforced seriously. Keep the camera pointed at the terminal.
🛂 Border Rules: e-Arrival Card, K-ETA Waiver & Visas
Three separate questions to answer before you fly, in order.
✅ The e-Arrival Card — mandatory for everyone from 1 January 2026
This is the 2026 change. Every foreign traveller entering Korea must submit the Korea e-Arrival Card online, free of charge, within 72 hours of arrival. It replaces the old paper landing card and applies regardless of nationality, visa status, or K-ETA status — including travellers who are both visa-free and K-ETA-exempt. Complete it at e-arrivalcard.go.kr and show the confirmation at immigration. Skipping it because you assumed “visa-free means nothing to prepare” is the most common mistake this year.
📋 e-Arrival Card — do it before check-in
Free, takes five minutes, valid for 72 hours before arrival. The URL is e-arrivalcard.go.kr. Do it the day before you fly, not at the airport. Visa-free travellers still need it.
🔓 K-ETA — waived for most Western passports through 31 December 2026
The K-ETA is Korea’s pre-travel clearance for visa-free visitors. A temporary waiver — extended through 31 December 2026 — covers a substantial list of nationalities: United States, United Kingdom, Canada, Australia, New Zealand, Japan, Singapore, Taiwan, Hong Kong, and EU member states including France, Germany, Italy, Spain and the Netherlands, among others. If your passport is on the waiver list, you do not apply for a K-ETA at all in 2026.
Nationalities not covered by the waiver still need one before boarding. It costs ₩10,000 (roughly US$7–8), is valid for up to three years or until passport expiry, and assessment can take up to 72 hours — apply several days before departure, not the night before. The waiver list has moved before, so check your passport’s current status at k-eta.go.kr rather than taking someone else’s word for it.
🛂 Visa-free entry and standard visas
Most nationalities on the K-ETA waiver list also enter visa-free for stays of up to 90 days for tourism or business — the two overlap but are technically separate. Travellers whose nationality is not on the visa-free list need a Korean visa arranged in advance through a Korean embassy or visa centre. There is no general visa-on-arrival for tourism at Cheongju.
The cleanest summary: check your visa-free status, then your K-ETA status, then complete the e-Arrival Card regardless. All three depend on your nationality, not on which airport you land at.
🛂 The order of operations
1. Confirm visa-free status (or arrange a visa). 2. If not on the K-ETA waiver list, apply for K-ETA at k-eta.go.kr at least 72 hours before departure. 3. Complete the e-Arrival Card within 72 hours of arrival at e-arrivalcard.go.kr. Step 3 applies to everyone.
🚌 Getting Into the City: Bus 747, Coaches & Taxis
The airport is 11 km north of central Cheongju. There is no rail or metro connection at the airport itself, despite the KTX line passing nearby.
🚍 Express bus 747 — the standard route
The 747 express bus runs from the terminal to Cheongju Bus Terminal in the city and out to Osong Station, the nearest KTX stop. Fare is ₩1,900 cash or ₩1,800 with a T-money or compatible transport card; the run to central Cheongju takes about 20 minutes. If your next move is the high-speed train to Seoul or Daejeon, the 747 to Osong handles that leg. Korean buses expect exact-ish cash if you are not tapping with a card — have small notes ready.
🚌 Bus 747 — ₩1,900, ~20 min
Runs from the terminal stop to Cheongju Bus Terminal and Osong KTX Station. Pay ₩1,800 by T-money card or ₩1,900 in cash. The card saves you the change problem. Departures are frequent during the day; check timings in the evening.
🗺️ Intercity coaches to Seoul, Daejeon and beyond
Direct intercity coaches leave from the stop in front of the terminal to Seoul — Nambu Terminal, Central City and the COEX area — plus Daejeon’s main complex and Yuseong, and on to Cheonan, Chungju and Incheon. The Seoul run is roughly 1.5 hours. Tickets are from a self-service machine that takes cash or card; coach fares change, so check the current price at the machine rather than trusting any figure including this one.
🚕 Taxis
Metered taxis wait outside arrivals. Given the short 11 km distance to central Cheongju, a taxi is a reasonable call when the buses are thin — late evenings, heavy luggage, non-standard timing. Use the official rank; the standard overcharge trap here is anyone inside the terminal offering a flat “airport price” for a private car.
🛋️ Lounges: The Honest Version
Cheongju has no Priority Pass, LoungeKey or DragonPass lounge. Those networks operate at Incheon, Gimpo, Jeju and Busan/Gimhae — not here. Whatever your card or membership entitles you to at bigger airports, it does not get you through any door at CJJ.
What the airport has is a small airport-run business lounge on the third floor of the international side, open roughly 08:00–20:00. Basic seating, beverages, meeting facilities — somewhere to sit quietly, not a hot buffet with showers. The practical takeaway: if a lounge is part of your travel routine, plan around it at whichever larger airport bookends your CJJ flight, not here.
🛋️ No network lounges at CJJ
Priority Pass, LoungeKey, and DragonPass do not operate here. The airport business lounge on the 3rd floor (08:00–20:00) is the only option — basic seating and drinks. This is a gate-and-café airport.
🍽️ Food Before You Fly
The terminal offers standard Korean airport fare — Korean staples and coffee on the landside, priced as airport food is priced everywhere. If your schedule allows any margin before arriving at the airport, eat in Cheongju instead. The city has the full range of Korean restaurants at normal prices, and the 20-minute bus back makes it feasible on a generous schedule.
For departing international passengers, there is a duty-free shop in the international departures area with the standard liquor, tobacco, perfume and cosmetics. The more useful facility for travellers who have been shopping in-country is the tax-refund desk: Korea operates a VAT refund scheme for foreign visitors on qualifying purchases, and Cheongju’s international side handles refunds for eligible receipts. Keep your tax-free paperwork from any in-country shopping and process it at the desk before you leave. The threshold and procedure are set nationally and adjust periodically — confirm the current rules at the desk.
🗺️ Layover Reality: Cheongju in a Few Hours
The airport’s proximity to the city is the one genuine argument for leaving the terminal on a layover. Eleven kilometres, 20 minutes on the 747 bus — that is genuinely close by Korean airport standards. The question is what you do with it.
Cheongju Early Printing Museum is the most distinctive reason to make the trip. The museum stands on the old grounds of Heungdeoksa Temple, where the Jikji was produced in 1377 — the world’s oldest surviving book printed with movable metal type, some 78 years before Gutenberg’s Bible. That detail is Cheongju’s headline claim, and the museum is built around it. It is the obvious single target on a short layover.
Sangdang Sanseong, a Joseon-era mountain fortress with walls running over 4 km, offers a long ridge walk with views across the city. Reaching it requires a local bus from town rather than a direct connection from the airport, which adds time in layers.
Cheongnamdae, a former presidential retreat on a lake further out, is a half-day destination — interesting if you have the time, unreachable on a tight connection.
💡 Layover maths — be honest with yourself
Round-trip transit by bus is 40–50 minutes including waiting and walking. Add the international check-in buffer you need before your outbound flight, and the window for actually being somewhere shrinks fast. The Early Printing Museum is realistic at around 5 hours or more. Sangdang Sanseong and Cheongnamdae need closer to a full half-day because of the in-city transfers. Under roughly 3 hours, the terminal wins.
Seoul is the wrong target. The coach to Seoul is roughly 1.5 hours each way — three hours of travel before you have seen anything. That calculus only works if you are deliberately staging through Cheongju en route to the capital, not on a layover between flights.
💳 Practical Notes
Payment. Korea runs on cards — contactless is accepted at shops, restaurants and taxis. The gap is local buses, which work smoothest on T-money or a compatible transport card; buy and load one at a convenience store. Keep some won for buses and small vendors.
Connectivity. Korea has fast, widely available mobile data and public Wi-Fi. There is no national app-blocking, so global apps work normally. A travel eSIM or a SIM bought on arrival covers the rest.
Currency exchange. Airport counters apply a markup, so change only what you need there and use a card or city ATM for the main spending. The won trades at roughly ₩1,500 to the dollar and ₩1,750 to the euro as of May 2026.
⚠️ Re-read the border section before you fly
The e-Arrival Card is mandatory for all foreign arrivals from 1 January 2026 — visa-free travellers included. Complete it at e-arrivalcard.go.kr within 72 hours of landing. This is the piece that catches people who have flown Korea before and assume the rules are unchanged.
