The closest large one is Cheongju International Airport/Cheongju Air Base (K-59/G-513) (CJJ), 23 km (14 mi) from the centre, with a longest runway of 9,000 ft, which limits it to short and medium-haul aircraft. The alternatives are Gunsan Airport / Gunsan Air Base (KUV, 98 km).
| Airport | Code | From centre | Longest runway | Elevation |
|---|---|---|---|---|
| Cheongju International Airport/Cheongju Air Base (K-59/G-513) | CJJ | 23 km (14 mi) | 9,000 ft | 191 ft |
| Gunsan Airport / Gunsan Air Base (regional) | KUV | 98 km (61 mi) | 9,000 ft | 29 ft |
Runway length is a practical tell: at 9,000 ft, CJJ handles short and medium-haul aircraft, so a long-haul trip will connect somewhere else first. The airport sits at 191 ft; that is low enough that altitude never restricts departures.
