Almost every call our 24-hour line receives begins the same way. A partner, a parent, a sibling who has not heard back from someone who should already have cleared passport control an hour ago. A quick voice, an unfamiliar country code, then the question that matters: what do we do now? The purpose of this guide is to give that person — and the traveller themselves, should they still be in a position to read it — a clear, honest map of the first twenty-four hours. Airport detention in Europe is highly structured. It has phases. Knowing those phases makes it possible to use the time well.
A word before we begin. This guide describes what typically happens at land, air and sea borders across the EU and Schengen, as well as Switzerland and the United Kingdom. The specifics vary by country, airport and individual officer. None of what follows is legal advice for your particular case — for that you will need to speak with a lawyer directly. What you will find here is the shape of the process.
The hour-by-hour shape of detention
Airport detention is not a single event. It is a sequence of handovers — from border officer, to supervisor, to border police, to judicial authority — each with its own time limit and its own legal threshold. The board below reconstructs a typical European timeline. What matters is not the exact hours, which vary, but the order of the phases and which of them is the critical moment to involve a lawyer.

An illustrative reconstruction of a typical detention sequence at a Schengen border. Exact timings vary by country.
What each phase actually feels like
Primary passport control — the moment the machine beeps
At the first booth, an officer scans the passport. If their system flags anything — a Schengen SIS II record, an Interpol match, a sanctions hit, a visa irregularity — the traveller will be asked to step aside. This is not yet detention. It is the officer following a routine: their duty is to hand off, not to decide. Expect to be asked to wait to the side, and to have the passport retained.
Secondary inspection — the quiet room
This is the phase that most shapes the outcome. In a separate room, border police will ask questions — about the trip, the host, the sums on the declaration form, the employer, sometimes matters that appear to have no connection to the flight. The traveller's phone may be requested, and, in some jurisdictions, searched. The purpose of this phase is to decide whether the flag is real, whether it warrants further steps, and, crucially, whether the person should be released, admitted, or handed over to national police.
Many travellers assume that being cooperative at this stage — answering every question, explaining every detail, unlocking the phone willingly — will speed up release. Sometimes that is true. Often it is not. What you say in secondary inspection can be written down, signed, and used against you hours later in a judicial proceeding that you did not yet know was coming. There is a reason the right to remain silent exists in every European jurisdiction — and a reason EU law specifically preserves it at this phase.
Identity verification and the lawyer window
If secondary inspection does not resolve the matter, identity verification follows — fingerprints against the Schengen VIS and AFIS systems, checks against national criminal records, and, where relevant, formal contact with Interpol's National Central Bureau. At some point in this phase — the exact moment depends on the country — the legal right to a lawyer becomes actionable. This is the single most important window of the entire sequence.
Referral decision and custody
A supervisor, typically within four to eight hours, decides whether the traveller is released, admitted subject to conditions, or formally transferred into the custody of criminal police or immigration authorities. From that transfer onward, the clock that matters most is the constitutional one: nearly every European country requires that a detained person be brought before a judge within 24 to 48 hours. That judicial hearing is where, for the first time, the evidence is tested rather than merely recorded.
What to do — and what absolutely not to do
Most of the following will read as obvious when you are calm. None of it reads as obvious when you are the one being held. Anyone travelling to or through a European border where there is any possibility of a database issue ought to have read this list once — and ideally shared it with one person who will remember it on their behalf.
"The right to silence is not an admission of guilt. It is a well-established safeguard designed for exactly the situation in which you find yourself — tired, afraid, in an unfamiliar language, being asked questions whose legal significance you cannot yet assess."
What the family should do — on the other side of the wall
The family, usually, finds out by absence. The flight landed; the person did not come through arrivals. Messages go unanswered. There are three useful things to do in the first hour, in order.
- Confirm the flight actually landed and that the person is not, for instance, on a delayed onward connection. A quick check of the airline's status often resolves the worst fear before it takes hold.
- Call a lawyer with cross-border detention experience — not the general emergency number, not a personal contact in a different country. The first hour of counsel time is worth ten of it later.
- Prepare the documents the lawyer will ask for: copy of the passport, travel itinerary, the host's address, any prior legal matters abroad, and a list of every database concern that might be relevant. Having this ready saves hours.
Please do not post on social media while the situation is unfolding. It is entirely understandable that you want to alert people, seek help, apply pressure. In practice it almost always complicates the legal response — sometimes by tipping off the requesting state, sometimes by hardening the position of the authority currently holding the person. Quiet work resolves more cases than loud work.

The good news, which is usually the true news
Most people stopped in secondary inspection are released the same day. A database flag often turns out to be a false match, or an outdated record, or a question that is resolved once a supervisor looks at the full file rather than the alert. The small number of cases that progress beyond the first six hours are almost always the ones where something real is in the underlying record — and those are precisely the ones where early legal involvement matters most.
What we ask of our own clients, and what we would ask of anyone reading this, is simply this. If there is any reason to believe a border encounter could produce a question — an old matter abroad, an uncertainty about a foreign proceeding, a rumour that you might be listed somewhere — resolve it before the flight, not at the airport. A legal check in our office costs a known amount, done in a known time, with a known result. A detention does not.
And if you are reading this because you are already at the airport, or because someone you love is — close this tab, and call us. We will pick up.
