Europe to Seoul via China from €538, if your passport qualifies

Quick summary

China’s visa-free transit now covers 57 nationalities and runs up to 240 hours as of August 2026, up from 53 nationalities and a 144-hour maximum, and still requires a confirmed onward ticket to a third country. Our fare scan on 11 October 2026 found London–Seoul round-trips from €538, one stop, for a 15 November departure.

Near-term October departures in the same scan priced between €1,277 and €1,751, so the date matters more than the hub. A passport outside the 57-country list needs a full Chinese visa, which removes the advantage.

As of August 2026, China’s visa-free transit rules give eligible travelers more time in the country. The paperwork has eased, but near-term fares have moved against them. For anyone flying from Europe to Seoul, the calendar now moves more money than the airline name.

The route was long sold as a simple saving: fly Air China via Beijing or China Eastern via Shanghai and undercut the European carriers’ direct fares. That pitch rests on more than the ticket price. Your passport and onward booking decide whether the connection works without a Chinese visa. A visa usually marks the point where it stops being the cheaper option.

The fare gap for the same origin and destination reached €1,213.

What the current visa-free transit rules actually allow

China’s transit-without-visa scheme is set nationally, and its scope has widened. It now covers 57 nationalities, up from 53, according to the provincial visa guidance published for foreign nationals. The maximum stay has grown from 144 hours to 240. That new option sits beside the existing 24-, 72- and 144-hour windows.

The window you receive depends on your passport and the port you connect through, not the length of your itinerary.

One document unlocks transit: a confirmed onward ticket to a third country. That means a booking that takes you out of China to somewhere else; the Beijing-to-Seoul leg of a Europe–Seoul trip fits that rule. The requirement is checked against the national list of eligible nationalities. It is the condition travelers most often assume is optional.

A separate Chinese visa exemption is easy to confuse with transit. It lets citizens of 50 countries, South Korea among them, up from 45, enter China for up to 30 days without a visa, per Beijing’s municipal government. It is permission to enter China as a destination, not a transit allowance. It does not replace the onward-ticket condition when China is only a connection.

Eligibility comes before hub, layover length and price. The two rules grant different kinds of permission.

Which Chinese airports qualify for transit

Three Chinese hubs sit at the centre of Europe–Seoul connections: Beijing Capital (PEK), Shanghai Pudong (PVG) and Guangzhou Baiyun (CAN). All three are confirmed transit ports under the scheme. The city you connect through is therefore part of the eligibility test, not an administrative detail.

Hub choice also shapes the trip. A Beijing or Shanghai connection can become a multi-day stop instead of a terminal wait. Travelers who qualify for the separate entry exemption can treat China as a destination rather than a corridor.

The onward booking has to be in place before departure, not arranged on landing. Whether you spend four hours or four days on the ground, that confirmed ticket out of China makes the transit arrival legal without a visa.

How to check whether a routing via China still makes sense

Our fare scan on 11 October 2026 looked at London–Seoul round-trip economy and returned 25 itineraries. The cheapest was €538 with one stop. It departed 15 November and returned 23 November. The dearest was €1,751 for a 16 October departure.

The lowest one-stop fares cluster in November and again in January and February 2027. Near-term October departures ran from €1,277 to €1,751.

Stops matter too. The only itinerary in that scan with no stops priced €896, some 67% above the cheapest one-stop fare. Everything under €610 involved one or two connections. That is the trade a China-hub routing asks you to make: the connection is where the cheap seats are.

For an eligible traveler holding the onward ticket, a Chinese connection can be an ordinary itinerary. For everyone else, the fare saving has to cover more than the flight.

Route economics sit behind the fare grid. Air China and its peers still hold the northern corridor over Russian airspace. How Chinese carriers’ cost base on Europe–Asia routes works sets out the mechanism that keeps these routings viable; the flight options from Europe to South Korea page lists connection choices by departure city.

What the longer transit window changes

The longer stay gives travelers more room to shape a connection. The practical task is knowing which permission covers the trip before searching for a fare: is your passport on the transit list, and can you show a confirmed ticket onward to a third country?

Planning China as a stop. Choose the port that suits your onward flight and make sure the onward booking sits on the same itinerary. Less suited: travelers whose passport is on neither the 57-country transit list nor the 50-country exemption list.

Passport outside both lists. A Chinese visa becomes mandatory, and its cost and processing time come straight off any fare saving. Price the fare grid first and the visa second, not the other way round. Less suited: anyone who would rather decide after the ticket is issued.

Booking into 2027. Our scan’s cheapest December itinerary, at €896 departing 24 December, is the last window where the current rules are certain. Less suited: travelers who need certainty before Beijing confirms what happens after 31 December 2026.
