Incheon International Airport ICN

A proper bed in the secure area, in your terminal, without immigration.

• There is one in each terminal on the 4th floor near gate 11 in Terminal 1, opposite gate 251 in Terminal 2. Use the one in your departure terminal: the shuttle between them goes through the city side.
• You can book it in blocks of a few hours or overnight, and it is for international connecting passengers.

A proper room beside Terminal 2, when your layover warrants a full night.

• Choose it if your flight leaves from Terminal 2: you avoid the inter-terminal shuttle after waking.
• You must pass immigration both ways, with electronic authorisation if your nationality requires it.

⭐ The rule you now meet everywhere began here, after a fire

On 28 January 2025, a power bank in an overhead locker caught fire aboard a Korean aircraft: twenty-seven people were injured and the aircraft was badly damaged. Since then, every departure from Korea follows the strictest rule in the world, regardless of airline. Keep power banks ON YOU in the seat pocket or under the seat, never in the overhead locker with terminals taped over or stored in a closed pouch. You cannot charge devices in flight, and since January 2026 Korean airlines have banned their use on board altogether. At check-in, staff validate them with a sticker. If you planned to recharge the camera housing on the flight to the island, make another arrangement. If this rule feels familiar, that is because Korea took it to international civil aviation, which made it the global standard in spring 2026.

Keep a towel and a change of clothes IN THE CABIN

Incheon is one of the rare airports where you can shower and sleep free between two long flights. But towels are not provided, and your checked bag goes through to your final destination: it will not join you on the 4th floor. A microfibre towel and a clean T-shirt in your hand luggage transform an eight-hour layover here and weigh nothing beside the regulator already in it.

Changing terminals means going back through the city side

The shuttle between Terminal 1 and Terminal 2 runs through the public area. You therefore leave the secure zone, spend twenty-five to thirty-five minutes gate to gate, then go through security again and immigration too, depending on your ticket. With dive kit to collect and recheck, this is the step that eats the whole margin. Check the terminal number for your second flight before booking, not after landing.

The free shower is for connecting passengers only

This is the condition not printed in large type: the four shower areas on the 4th floor are free to anyone showing a boarding pass for an onward flight. If Seoul is your final destination, or you have gone out and returned, you will be asked to pay. Shower before going into the city, not after.
