South Korea: Onward Ticket & Return Flight Requirements
South Korea requires a return or onward ticket for entry, even for K-ETA-exempt travelers. Airlines run Timatic checks at boarding and can deny a boarding pass without a confirmed return or onward reservation. From January 2026 a separate e-Arrival Card is also mandatory.

Do you need a return ticket for South Korea?
Yes. A return or onward ticket is part of South Korea's entry requirements. Even travelers who are exempt from the K-ETA — and even those who hold an approved K-ETA — must still be able to show proof of onward travel. The K-ETA authorises your trip; it does not replace the onward-ticket requirement.
Airlines run Timatic checks at boarding
The decisive checkpoint is the airline desk. Carriers run Timatic checks before boarding and can refuse to issue a boarding pass if you cannot show a confirmed return or onward reservation. Because the airline bears the cost of a refused passenger, this is checked consistently.
The new e-Arrival Card (from January 2026)
Separately from the onward-ticket rule, from 1 January 2026 every foreign traveller entering Korea — including K-ETA-exempt nationalities — must submit a free e-Arrival Card online within 72 hours before arrival. It replaces the paper arrival card and does not affect the onward-travel requirement, which still stands.

Do I need a return ticket if I'm K-ETA exempt?
Yes. K-ETA exemption lets you travel without the authorisation, but you still need a valid passport and a return or onward ticket, and airlines check it at boarding.
Does an approved K-ETA mean I don't need an onward ticket?
No. An approved K-ETA does not exempt you from proof of onward travel. Airlines run Timatic checks and can deny boarding without a return or onward reservation.
What is the e-Arrival Card for South Korea?
From January 2026, a mandatory free online entry declaration that every traveller must submit within 72 hours before arrival. It replaces the paper card and is separate from the onward-ticket requirement.
What if my onward flight isn't booked?
A verifiable flight reservation gives you a confirmed onward ticket that passes airline Timatic checks, letting you board without committing to a fixed departure.
