Arriving at Incheon Airport: the first two hours, in order

Arriving at Incheon Airport is a series of small decisions made while tired, and a few of them are hard to undo. Some things are much easier at the airport than in the city. Others are noticeably more expensive there and worth waiting for. This is the order, with what each step actually costs and which of them you can safely skip.

Before you land

Check whether you need a K-ETA. Most visitors currently do not, and the ones who do are the ones getting overcharged by lookalike websites. It is a before-you-fly item, not an airport item, and it is covered in the K-ETA guide.

Fill in the customs declaration on the plane. If you are over the USD 800 allowance, or carrying anything in the restricted categories, declaring it is straightforwardly cheaper than not. The customs guide has the numbers and the list of things that are refused regardless of value.

At the airport, in this order

1. Immigration, then baggage, then customs. Nothing to decide here. Meat, fresh food and plants go in the declaration, not in the green channel.

2. Data. This is the one thing genuinely worth doing before you leave the building, because everything after it is easier with a working phone. Whether you want an eSIM, a physical SIM or a rented router is decided by two questions that are not about price, and the SIM and eSIM guide covers them. If you bought an eSIM before flying, activate it on airport wifi and skip the counter.

3. Cash, a little. You need a small amount for transit card top-ups, which are cash only. The airport is not the best exchange rate in the country but the difference on the amount you actually need now is small. Do not change a week's spending here.

4. A T-money card. Buy it at a convenience store in the terminal, load it with cash, and use it on every bus, subway and most taxis for the rest of the trip. The card itself is a purchase and nobody refunds it, but the balance you load onto it does come back, and getting that back has rules most English guides get wrong. The T-money guide sets them out.

5. Into the city. Four ways, and the cheapest is not the answer for everyone. The one question that decides it is where you are sleeping tonight, not what each option costs. The airport transfer guide does the comparison, and if you would rather not carry anything, luggage delivery runs from the airport to a subway station near your hotel.

What to do later, not now

Serious currency exchange. City rates beat airport rates.

Shopping of any kind. Including duty free on the way in. The shopping guide covers where things actually are, and the tax refund guide covers getting the tax back, which starts at the till and not at the airport on your way out.

Working out the maps situation. Google Maps does not do walking directions here. You want the alternative installed, and doing it on hotel wifi with a coffee beats doing it standing in an arrivals hall. That is the maps guide.

The two that get harder once you leave

A Korean phone number. Most Korean apps, including delivery and some ticketing, want one for identity verification. If you decided you needed one and did not sort it at the airport, doing it later is a trip to a carrier shop with a passport rather than a five-minute counter stop.

Anything involving your card working. If your card is going to be refused here, you want to find that out in an airport with alternatives around you rather than at a ticket machine at eleven at night. Buy something small, early. The declined card guide explains which of the four walls you have hit and which two have a way through.

Then the ordinary things

Once you are in the city, the questions get smaller and more frequent: how to order when the machine only speaks Korean, what to do when a restaurant will not serve one person, which number to call if you get ill, what the taxi meter is actually doing. Those are all in the guides, and each of them carries the date its figures were last checked.

What the front page carries is today: the exchange rate, the air quality, the temperature, and whether anything is closed. That part changes daily and it is the reason to come back rather than to bookmark.

Quick answers: arriving at Incheon

What should I do first when I arrive at Incheon Airport?

In order: immigration, baggage and customs; then data (activate your eSIM on airport wifi or buy a SIM); then a small amount of cash for transit top-ups; then a T-money card from a terminal convenience store; then the train, bus or taxi into the city, decided by where you are sleeping.

Should I exchange money at Incheon Airport?

Only a small amount. You need cash for T-money top-ups, which are cash only, but city exchange rates beat the airport's. Do not change a week's spending at the airport.

Where do I buy a T-money card at Incheon Airport?

At any convenience store in the arrivals area. Load it with cash and use it on every bus, subway and most taxis. The card itself is not refundable, but the balance you load is.

Is it better to buy a SIM at the airport or in the city?

If you want a Korean phone number, the airport is easier: a carrier shop in the city means a passport visit and more time. Data-only eSIMs can be bought before you fly and activated on airport wifi, skipping the counter entirely.
