Airport transit visas: when a layover needs a visa (Schengen, UK, US, Canada)

Whether a layover needs a visa depends on your nationality and on where you walk. In the Schengen area and the UK, staying inside the transit area needs a visa only for listed nationalities, and leaving it needs the permission a normal visit needs. Canada and the US ask for a permission for most air connections. The part travelers trip over is leaving the transit area without meaning to: changing airports, collecting bags or booking two separate tickets can all do it.

This guide covers the Schengen area, the UK, the US and Canada, which handle the question differently. It does not list every nationality, because the lists change and the official tools are quicker, but it shows where to look and what each term means. Everything below was read on 2 October 2026.

The UK uses the words airside and landside, and the Schengen rules speak of the international transit area, but the idea is the same. Airside means you stay in the transit area and never pass a border officer. Landside means you pass border control and enter the country, even briefly. The GOV.UK layovers page defines both for the UK: airside is when you do not pass through UK border control before your connecting journey, and landside is when you pass through it, come back through and leave within a short time, usually 24 hours.

Schengen area

The European Commission's FAQ separates two cases. Transit through the international transit area means your onward journey does not leave that area. Transit via the territory of a Schengen state, even if limited to an airport, means you leave the transit area.

The Commission's page on applying for a Schengen visa summarizes the three groups: nationals who need the visa at any Schengen airport, nationals of additional countries who need it at specific states, and categories of people who are exempt. The legal base is Article 3 of the Visa Code.

The line between the two cases matters more than it looks. The same FAQ says that travel to a Schengen state via another Schengen airport is not airport transit, nor is travel to a non-Schengen country via two Schengen airports. Flights between Schengen states are treated as domestic. Depending on your nationality you may need a short-stay visa as you enter, even if you stay only a few hours and remain in the airport outside the international transit zone.

United Kingdom

GOV.UK offers three routes, and which applies depends on whether you pass border control.

The sources are GOV.UK's transit visa overview, the pages for the Direct Airside Transit visa and the Visitor in Transit visa, the ETA guidance and the list of people who do not need an ETA. The fees are as shown on those pages on 2 October 2026, and GOV.UK adds that the Direct Airside Transit fee may change slightly depending on the country you apply in.

The Home Office publishes a "UK visa requirements" poster for airlines, last updated August 2026. It states that airside passengers do not change airports or pass through the UK border, and that they cannot transit airside to the Republic of Ireland or anywhere in the Common Travel Area. For travelers who need a visa, the poster sets out a transit-without-visa scheme, with one set of conditions for airside and another for landside. For airside the traveler must arrive and depart by air, have a confirmed onward flight leaving the same day from the same airport, and hold the right documents for the destination. For landside the onward flight must leave before 23:59 the following day. It also says an immigration officer decides whether to allow a transit under the scheme.

United States

The US no longer runs a transit-without-visa route. The State Department's Foreign Affairs Manual says that transit (C) visas are for people in immediate and continuous transit through the US en route to another country, and that the Transit Without Visa program has been suspended indefinitely.

The text is in 9 FAM 402.4, last revised 14 February 2024 according to its header, and in CBP's ESTA and Visa Waiver Program FAQ. The FAQ also says ESTA approvals are typically granted for two years or until the passport expires, whichever is sooner. Our ESTA guide covers the application.

Canada

IRCC's transit page sets two rules by nationality.

The transit visa conditions are on IRCC's eligibility page. A Transit Without Visa program lets some travelers transit without a visa when going to and from the United States. IRCC names citizens of China, Indonesia, the Philippines and Thailand, and holders of Taiwan passports without a personal ID number, under certain conditions. Our Canada eTA guide covers the eTA itself.

Three groups carry most of the risk.

The first is travelers whose nationality is on a transit-visa list. In the Schengen area and the UK that means a visa even if you never leave the transit area. The lists are long and the official tools are quicker than a summary, so use those: the Commission's visa pages and the embassy of your connecting country for Schengen, and the UK visa checker for the UK. For Canada, IRCC's check tool on its visit pages asks for your passport country. For the US, the answer is the same for everyone who needs a visa to enter: apply for a transit visa or use an ESTA if your country takes part.

The second group is travelers holding a visa for another country, which can exempt them. The Commission's Visa Code Handbook, the guidance behind the Visa Code, lists holders of a valid uniform visa, national long-stay visa or residence permit from a Schengen state, and holders of valid visas from Cyprus, Ireland, Canada, Japan and the US. A visa from one of those five exempts you whether you are going to that country or to another one, and it covers the return trip if it follows immediately. The handbook is explicit that a UK visa does not exempt anyone from the Schengen airport transit visa. The UK has a similar list in its carrier poster, built around valid visas for Australia, Canada, New Zealand and the US.

The third group is anyone whose layover becomes a border crossing. The Home Office poster counts changing airport, collecting baggage and arriving at an airport where no airside transfer is possible as landside transit. The Commission adds that two Schengen airports on one journey is not airport transit. Self-transfers, where you book two unconnected tickets, are the usual way this happens, because your bags are not checked through and you have to collect them.

• Write down the airport and whether the two flights are on one ticket. Bags that are not checked through have to be collected, and the Home Office poster counts collecting baggage as landside transit.

• Ask the airline whether the connection is airside. GOV.UK says to check with your airline if you are not sure your transit qualifies.

• Look up your passport country in each official tool, once for the connection and once for the destination.

• If you have a visa, an ETA, an ESTA or an eTA, read what it covers for transit. The US and Canada require theirs for connections. The UK does not require an ETA airside.

• Allow time for a transit visa application. The UK Direct Airside Transit page does not give a processing time, and the Schengen consulate where you apply sets its own, so ask before you buy a ticket.

• Save the official pages and the date you read them. Rules for transit are applied by the officer or the airline on the day.

The UK ETA is the moving part. GOV.UK lists airside transit as an exemption on its page for people who do not need an ETA, while the Home Office's April 2026 ETA factsheet words it more narrowly: passengers transiting Heathrow and Manchester without going through passport control do not currently need an ETA. Treat the exemption as current and check it again before you fly.

The other sources carry their own dates. The US manual chapter was last revised on 14 February 2024, the Commission handbook is dated 26 June 2024, and the Home Office poster was last updated in August 2026. None of them announces a change, and none shows a dated 2026 change to the Schengen, US or Canadian transit rules. The EU's ETIAS is not yet running, so it does not affect connections today. See our ETIAS guide for its status, and our EES guide for what happens if you do enter the Schengen area.

Check the connecting airport before the destination, since that is where the transit rule applies. If any leg forces you out of the transit area, apply for the permission a normal visit to that country needs. Keep the rebooking rules of both airlines to hand in case a missed connection pushes you into the arrivals hall.

Also check the passport. Countries you pass through can ask for more validity than your destination, and our guide to the six-month passport rule shows the figures. For cover if a missed connection forces an unplanned night, see our travel insurance guides.
