Incheon Airport to Seoul: which transfer is cheapest?
The train is priced per passenger and a taxi is priced per car, so the answer moves with your group size — but not as far as people expect: splitting a taxi four ways still lands above the all-stop train fare, and a fifth passenger needs a second car. Arrival hour matters more, because the airport railway and most limousine services stop overnight. Put your group and your landing time in below.

AREX Express Train — ₩13,000 each
₩26,000 for the group, 43 minutes. A taxi never wins on price here, at any group size — splitting the fare does not close the gap. It is a choice about time and doors, not money.

Same trip, next decision
Why a seller would not tell you this
Every option here is sold by someone with no reason to point at a cheaper one. The railway does not tell a family of four to consider a taxi; the taxi stand does not mention that splitting the fare still loses to a train ticket. This page includes every option and will tell you when the expensive one is the wrong choice.
What we compare, and what we don't
We compare transport cost and journey time only. We do not price comfort, and we do not assume what your time is worth — that is an input you set, and it is zero by default. Journey times are typical rather than measured; traffic moves them more than any figure we could publish.
Quick answers
Is a taxi from Incheon Airport cheaper if we split it?
It gets cheaper per person, but not cheap enough to beat the train. A taxi is priced per car rather than per passenger, so four people pay a quarter each — yet that quarter is still well above the all-stop AREX fare, and a fifth passenger needs a second car, which pushes the per-person cost back up.
What can I take from Incheon Airport in the middle of the night?
The airport railway and most limousine services do not run overnight, so the choice narrows to a night bus or a taxi. A comparison based only on published fares will point at options that are not running at that hour, which is why arrival time is an input here.
Does the cheapest option change if I have large suitcases?
The cheapest fare is usually the all-stop train, which involves transfers and stairs. With large suitcases the ranking shifts to options that take hold luggage, but the cheaper option is still shown rather than hidden — that trade is yours to make, not ours.
