Flights to South Korea from Thailand: the SiamFlights catalogue lists 3 routes from 3 Thai airports, flown by Thai Airways, Korean Air, Asiana Airlines, T’way Air and Jin Air. The main demand here is ASEAN and regional leisure travel. Local currency KRW; fares are shown in THB.
Visa & currency — South Korea
We record 1 visa rule(s) for a Thai passport travelling to South Korea, where the local currency is KRW, across 3 corridors from 3 Thai airports in our catalogue. Visa rules attach to the passport’s nationality, never to the airline or the fare.
Thai passport to South Korea: check visa rules with the embassy. Keep passport valid ≥6 months. Local currency KRW. Check with the destination’s embassy or immigration authority before buying a ticket.
South Korea — the rule we record. K-ETA required (Electronic Travel Authorisation) · KRW 10,000 · 90 days per entry Results generally arrive within 72 hours, so apply well before travel; checked 2026-10-23. Verify the current text at the official source. Requirements change without notice — confirm with the embassy or the immigration portal before buying a non-changeable ticket.
What visa-free does not mean. Entering without a visa in advance is not a right to work, not a right to study, and not a guarantee of admission — the officer at the border still decides. The conditions most often forgotten are remaining passport validity, an onward ticket and proof of accommodation. All three are asked for more often than travellers expect, and their absence lets the airline refuse boarding at the departure airport.

|---|---|---|---|---|---|
| Bangkok (BKK) → Seoul (ICN) | TG, KE, OZ, TW, LJ | 56× | 5.5 | ฿4,292 | BKK-ICN |

Frequencies here are estimates of the standard schedule. They describe the shape of the network, not the timetable for your dates. Carriers add and cut rotations seasonally and some corridors operate only in certain months. Use these to compare which routes are dense and which are thin, then confirm your actual dates against the airline’s schedule.
The route guides carry what this table cannot. This is a country-level summary; each city-pair page holds monthly readings, the weekly fare series we have captured, and carrier detail per corridor. If you already know your city pair, start there — the picture will match your plan far more closely.

This lists carriers on the corridor, not every way of getting there. We show the airlines recorded on direct routes from Thailand to South Korea. Connecting itineraries through regional hubs do not appear here and are sometimes materially cheaper. The trade is time plus one more point where the plan can break — compare total price against total journey time, not price alone.
Carrier nationality changes what you are owed. Korean Air and Asiana Airlines are registered in South Korea. Thai Airways are Thai-registered. Passenger rights are set first by the country the flight departs from, and in some jurisdictions — the EU and UK notably — the carrier’s nationality extends cover to inbound flights as well. Choosing an airline therefore has a genuine legal consequence, not only a service and price one.
South Korea corridor character
Corridors to South Korea average about 5.9 hours of block time, split 3 medium-haul (4–7h), with 1 flagged as labour/migrant routes. 5 carriers appear across those corridors.
Routes to South Korea from Thailand mainly serve ASEAN and regional leisure travel. The average block time is about 5.9 hours. 1 of them are labour-migration or diaspora corridors. Compare month-by-month fares for each city pair on the route pages.
An average block time hides what matters. The 5.9-hour figure averages corridors of unequal length, and block time drives preparation more than people expect. Beyond six hours, meals, seat choice and sleeping on board become real variables; below it they barely register. Read the block time for the city pair you will actually fly, not the country average.
A country low is not your corridor’s price. The figure comes from one route in this group, and other corridors to South Korea can sit at an entirely different level because distance and capacity differ. It is useful for comparing country against country, not for budgeting a specific city pair. Take corridor-level pricing from that route’s own guide.
Best time to book
Across the 10 departure months in our mid-2026 snapshot on corridors to South Korea, the cheapest reading was Sep 2026 at ฿3,860 and the dearest May 2027 at ฿9,802 — a 154% spread. These are observations, not forecasts. Combined frequency is roughly 84 departures a week.
Fares to South Korea are cheapest outside Thai school holidays, Songkran and New Year. Book 4–8 weeks ahead; compare months in the route table and city-pair pages.
A cheap non-changeable fare has a hidden cost. The lowest fares usually carry no-change, no-refund conditions. If your documents, visa or schedule are not yet settled, the saving is routinely smaller than the replacement ticket you will buy when something moves. The safe order is paperwork first, price lock second.
Read the 154% spread correctly. The gap between cheapest and dearest month is what flexibility is worth across this group. It is computed from the lowest value we captured in each month, and those can come from different corridors month to month, so it is a country-level picture rather than any one city pair’s price curve. Use it to choose a month, then price the actual route on its own page.
Departure airports for South Korea
Corridors to South Korea depart from 3 Thai airports in our catalogue, each with a different route count and frequency — which feeds directly into the fare and into the options you have when a flight is cancelled. Combined frequency is roughly 84 departures a week.
- Bangkok (BKK) — 1 route, ~56×/wk
- Chiang Mai (CNX) — 1 route, ~7×/wk
- Phuket (HKT) — 1 route, ~21×/wk
Positioning into Bangkok is an option worth thinking through fully. If you are outside the capital and direct service to South Korea from your nearest airport is thin or expensive, flying into Bangkok and connecting internationally is often cheaper. The condition that matters is keeping the whole journey on one ticket. Split it and you absorb the connection risk, a second baggage charge and a fresh check-in yourself.
The departure airport changes both the price and the fallback. An airport with more routes and higher frequency gives you more options when something breaks, not merely a lower fare. Choosing between two, read weekly departures alongside price: a slightly cheaper seat on a twice-weekly corridor can become very expensive the moment the plan changes.
Passenger rights on flights to South Korea
We hold 3 corridors from 3 Thai airports to 1 destination airports. Departures from Thailand to South Korea fall under Thailand CAAT; the return falls under Korea MOLIT. What you are owed changes with the direction of travel and the operating carrier’s nationality — not with the fare you paid or the cabin you sat in.
No European-style compensation schedule applies here. The destination sits with Korea MOLIT, which typically imposes duty of care, re-routing and refund obligations but no fixed EU261-style cash bands. The enforceable floor is therefore the airline’s own conditions of carriage plus Thailand CAAT rules for departures from Thailand. Read the conditions of carriage before you buy — that is the document that actually binds you.
Baggage loss and delay run on a separate rulebook. An airline’s liability for baggage that is lost, damaged or delayed on an international journey sits under the Montreal Convention 1999 where both the origin and destination states are parties. The caps are denominated in SDR and revised periodically, so only the current figure is usable. This frame is entirely separate from delay compensation: you can have no compensation claim and still have a baggage claim.
