Flying to Europe With ETIAS: What Air Travellers Need to Know Before Departure

Air travel to Europe is about to gain an extra step before you even reach the airport. From the last quarter of 2026, the European Travel Information and Authorisation System (ETIAS) will become a requirement for travellers who do not need a visa to visit Europe. If you are flying to any of the 30 European countries that will require ETIAS, you will need to hold an approved authorisation before you set off.

This is not a visa, and for most travellers the process will be quick. But because the authorisation is verified by your airline and by border officers, it pays to understand how it fits into a typical journey by air.

When ETIAS applies and how to apply

Once the system is live, you will need to apply online before your departure. The only legitimate channels are the official ETIAS website and the official mobile app; if you are unable to apply yourself, you may authorise another person to submit the application on your behalf.

A few points are worth fixing in your mind before you travel:

• The authorisation is linked to the passport used in the application.
• You must travel with that same travel document — not a renewed or different passport.
• ETIAS is not yet in operation, and no applications are being collected at this stage.

Planning ahead matters because the requirement is tied to the trip, not to the airport you happen to use. If you are mapping out a journey now, it is worth reviewing the ETIAS application process so the new step does not catch you by surprise later.

Checks at the airport and at the border

At the airport, your ETIAS travel authorisation will be checked before you can board your flight. Because it is connected to a specific passport, carrying the wrong document means you may be refused boarding — a problem no amount of paperwork at the gate can fix on the day.

After you land, the authorisation is checked again at the border crossing point. ETIAS on its own does not guarantee entry: you still need to meet all the other conditions for crossing the external border, such as being able to explain the purpose of your stay and having sufficient means for it.

Transit and the 90-day limit

Connecting flights are treated carefully. If you are only stopping over in one of the 30 countries to change planes and you stay within the airport's international transit area, you will not need an ETIAS authorisation. But if you have to pass through passport control — for example to switch terminals or airports for your onward flight — then a valid ETIAS is required.

Finally, remember the time limit that underpins all short-stay travel: your total stay across the European countries requiring ETIAS cannot exceed 90 days in any 180-day period. That limit is cumulative across all of those countries, with Cyprus the one exception, where the 90 days are counted separately. Keeping a clear record of your entries and exits is the simplest way to stay on the right side of the rule.
