Route Tips
- Book your Incheon Airport arrival for daytime hours if possible—the Airport Railroad (AREX) is cheaper and easier to navigate than arriving at night when fewer trains run.
- US citizens need a valid passport but do not need a visa for stays under 90 days. Ensure your passport is valid for at least 6 months beyond your planned departure.
- Korean Air and Asiana both allow free changes on most fare types—useful if your plans might shift, unlike many budget carriers with rigid policies.
- Consider a stopover in Tokyo if you have time—the connecting route via NRT or HND often costs less than direct and lets you explore two cities.
- Download the Kakao T app before arrival for reliable taxi bookings and the T Money card for convenient public transport payments at convenience stores.

The sweet spot is 16-20 weeks before departure, particularly if traveling during peak season. For February-March or November travel, you can sometimes find deals as early as 5-6 months out, but 4 months is generally sufficient.
