Gate-side basics in Terminal 1
Just past security in Terminal 1, Travel Essentials Shop covers the last-minute stuff: phone chargers, power banks, earphones, basic toiletries, and travel-size cosmetics. Prices sit in normal-airport range, so expect to pay a little more than downtown Jeju but not luxury-boutique levels.
The shop sits airside near several domestic departure gates in Terminal 1, so you can duck in after security without backtracking. It keeps standard airport hours, roughly from first departures in the morning to the last evening flights, which works for most early Jeju–Seoul runs and late-night domestic hops.
You’ll see shelves of neck pillows, eye masks, compression socks, and simple carry-on bags, along with umbrellas and rain covers — handy with Jeju’s sudden showers. Phone accessories lean heavily toward recent Samsung and Apple models, so double-check compatibility if you’re carrying an older device.
Snacks lean Korean: instant ramen cups, packaged seaweed, tteok-style sweets, and canned coffee, alongside bottled water and soft drinks. Expect small markups of a few hundred won compared with city convenience stores. It’s fine for topping up on a drink and a snack before a short hop to Gimpo or Busan.
Tip: if you need a power bank, buy it here before boarding; in-cabin USB ports on some older domestic aircraft from Jeju can be unreliable or missing entirely.
