Asiana Airlines Lounge

Open until 22:40, this is Jeju’s longer-running international lounge

The Asiana Airlines Lounge in Terminal 1 stays open from 06:00 right through to 22:40, giving you a place to sit down when the Korean Air lounge has already closed. It serves international departures only, so you need to be through outbound immigration before you can reach it.

Figure this lounge in as a buffer for evening flights leaving after 20:30, especially on Asiana or Star Alliance partners using Jeju’s international side. Entry policies vary by ticket and status, but it’s positioned for passengers already airside in Terminal 1’s international zone, not for domestic hops up to Gimpo or across to Busan.

Food and drink line-up is basic by big-hub standards, and very little hard detail leaks out online, but expect the usual mix for a regional Korean lounge: light snacks, soft drinks, tea, and coffee, with anything more substantial handled on board or in the main terminal’s restaurants. Prices inside are rolled into your access fee or airline status, so you’re not paying per item once you’re in.

Seating tends to be more functional than stylish, with the real differentiator being the operating hours: that 22:40 closing time buys you roughly an extra hour of lounge time compared with Korean Air’s lounge options at CJU. Power outlets can be limited in older Korean lounges, so assume you’ll want a fully charged battery pack rather than counting on finding a socket at every seat.

There’s no strong pattern of regular behavior or horror stories in the usual forums, which usually means a small, quiet space handling a modest number of international departures each evening. That aligns with Jeju’s schedule, where peaks cluster around late afternoon and early night flights to cities like Shanghai, Tokyo, or regional Chinese airports.

Practical tip: if you have flexibility, time your lounge visit for the hour before boarding and skip a second drink in the terminal; those longer 06:00-22:40 hours mean you rarely need to rush in early just to “get value” out of the stop.
