Transit through Europe and ETIAS: Do you need authorization for a layover?
The question of transit is one of the most frequently asked questions about ETIAS. The answer depends on a single criterion: do you pass through Schengen border controls during your layover? If so, ETIAS is required. If you remain in the international transit area without passing through border control, ETIAS is not required for the connecting flight itself—but it will be necessary for your final destination if it is within the Schengen Area.
Summary: ETIAS required or not, depending on the type of transit
| Transit status | Is ETIAS required? |
|---|---|
| Transit through the international zone (airside) — without passing through Schengen border control | Generally no |
| Passing through Schengen border control (landside) — even for a connecting flight | Yes |
| Collect luggage and then check in again — two separate tickets | Yes |
| Overnight stay at a hotel away from the airport during the layover | Yes |
| Connecting flight between two Schengen airports | Yes — checked at the first port of entry |
| Transit through an airport outside the Schengen Area (e.g., Dublin, London Heathrow) | No — rules specific to that airport |
| Schengen transit → non-Schengen destination without leaving the secure area | Depends on the airport layout |
The fundamental principle: the Schengen border
The rule is the same throughout the Schengen Area: ETIAS is required as soon as you cross the Schengen external border, that is, as soon as you go through passport control to enter the Schengen Area. This may occur during a tourist trip, but also during a simple layover if your itinerary requires you to leave the airport’s international zone.
Airlines and carriers are required to verify that passengers have a valid ETIAS authorization before boarding flights bound for the Schengen Area. If you do not have an ETIAS and need to cross the Schengen border during your layover, you may be denied boarding at the airline’s expense.
Airside vs. landside transit: what’s the difference?
The key distinction is between airside transit and landside transit:
| Transit type | Definition | Border crossing? | ETIAS required? |
|---|---|---|---|
| Airside | You remain on the airside, in the airport’s secure international zone, without ever going through passport control | No | No for the layover — yes for the final destination if Schengen |
| Landside | You pass through passport control and enter the public area of the airport (or leave the airport) | Yes | Yes |
In practice, whether your connection is airside or landside depends on your ticket and the airport. If you’re traveling on a single ticket with checked baggage through to your final destination, your connection is usually airside. If you purchase two separate tickets or if your baggage needs to be collected and rechecked, you’ll have to go through the landside area—and thus cross the Schengen border.
Real-world examples by trip type
New York → Paris CDG → Rome (one-way ticket, checked baggage)
ETIAS is required. You will cross the Schengen border at Paris-CDG upon your first entry into the Schengen Area. The ETIAS check will be conducted at that time. Your connecting flight to Rome is an intra-Schengen flight and is not subject to any additional border checks.
Sydney → Dubai (Emirates) → Amsterdam (airside connection, single ticket)
Your layover in Dubai is outside the Schengen Area—no ETIAS is required for this leg of the trip. Upon arrival in Amsterdam (Schiphol), you will be crossing the Schengen border: an ETIAS is required to enter the Netherlands.
Toronto → Frankfurt (layover) → final destination outside the Schengen Area
If you remain in the international transit area in Frankfurt (airside) without going through passport control, ETIAS is generally not required for your layover. However, if your flight itinerary requires you to go to the landside area in Frankfurt, ETIAS becomes necessary. Check with your airline to see if your connection is airside or landside.
Montreal → London Heathrow (layover) → Barcelona
London Heathrow is not part of the Schengen Area—the United Kingdom has its own system (ETA). ETIAS is not required for a layover in London. However, upon arrival in Barcelona, you will be crossing the Schengen border, and ETIAS is required. Be sure to obtain your ETIAS before departing from Montreal.
Flight with an overnight stay in Paris before continuing on to Rome the next day
ETIAS is required. Any time you leave the airport, you will be passing through the landside area and thus crossing the Schengen border. Even if you’re staying at a hotel for just one night, you are entering the Schengen Area, and your ETIAS must be valid.
The Airport Transit Visa (ATV): A Rule Distinct from ETIAS
Regardless of ETIAS, certain third-country nationals are subject to the airport transit visa (ATV) requirement when transiting through a Schengen airport, even in the international zone and without crossing the border. This requirement applies to specific nationalities determined by each Member State, generally countries with a high migration risk.
The VTA and ETIAS are two separate systems: the VTA applies to nationals subject to the Schengen visa requirement; ETIAS applies to nationals exempt from the visa requirement. If your nationality is exempt from the Schengen visa requirement (and therefore eligible for ETIAS), you are generally not subject to the VTA. However, be sure to check the specific requirements of the transit country, particularly for France, Germany, Belgium, and the Netherlands, which apply this rule to certain nationalities.
Land and sea transit
The ETIAS rules apply to all points of entry into the Schengen Area, not just airports. If you are traveling through the Schengen Area by land—by train, car, or bus—or by sea—by ferry or cruise ship—and crossing the Schengen external border, ETIAS is required. Here are a few specific examples:
| Mode of transportation | Sample itinerary | Is ETIAS required? |
|---|---|---|
| Eurostar | London → Paris (entry into the Schengen Area in Paris) | Yes |
| Ferry | Dover → Calais (entry into the Schengen Area in France) | Yes |
| Mediterranean Ferry | Tunis → Marseille | Yes |
| Cruise | Stopover in a Schengen port | Yes, if disembarking and crossing the border |
| International train | Istanbul → Vienna (Schengen entry in Austria) | Yes |
ETIAS and Mediterranean Cruises
Cruises that call at ports in the Schengen Area (Barcelona, Marseille, Civitavecchia for Rome, Athens, Venice, etc.) raise a common question. The rule is as follows: if you disembark from the ship and go through passport control to visit the city, ETIAS is required. If you remain on board or disembark in a closed port area without border control, ETIAS is generally not required for the stopover. Check with your cruise line before departure to find out if border control is scheduled at the ports on your itinerary.
Practical tips for planning a layover in Europe
To avoid any issues while traveling through Europe, here are the key points to check before you leave:
| Action | Why |
|---|---|
| Check whether your connecting flight is airside or landside | Determine whether ETIAS is required for the layover |
| Check to see if your luggage has been checked through to your final destination | If so, your connecting flight is likely on the airside. If not, plan to go to the landside area. |
| Get your ETIAS before departure if you’re unsure | €20 and a few minutes online—better safe than sorry |
| Allow plenty of time for your layover | The EES system (in use since October 2025) may extend border control times at Schengen borders |
| Check the passport requirements | The passport must be valid and eligible for ETIAS (issued within the last 10 years and valid for at least 3 months after departure) |
