In an ideal scenario, a client contacts us months before travel. We file a request for access to the files that concern them, obtain written confirmation of what is actually recorded, and — if necessary — prepare a formal challenge through the appropriate channels. That process takes between four and nine months, and it works.
Seventy-two hours is not that scenario. But 72 hours is still enough to make decisions that meaningfully change the outcome — and, just as importantly, enough to avoid the three or four mistakes that turn a manageable worry into a detention abroad.
This guide is for the second scenario.
First, establish what you actually know
Most people who reach out to us before an urgent flight do not have a confirmed legal issue. They have a suspicion. And that suspicion almost always comes from one of four sources:
- A prior border incident — secondary screening, a longer-than-usual wait at passport control, unusual questions about a specific country.
- A visa refusal citing "security" or "other grounds" with no real explanation.
- News, a letter, or a warning from a relative about a case opened against them in a country they have since left.
- Nothing concrete — only the quiet knowledge that a dispute, a prosecution, or a political situation exists that could plausibly produce a problem.
The distinction matters. The response to a confirmed alert is very different from the response to an informed suspicion. Treat the two the same way and you either over-react (cancelling travel that was perfectly safe) or under-react (boarding a flight that should have been rerouted).
A public website search that returns nothing does not mean you are clear. Several layers of cross-border alerts are never public to begin with — they travel directly between member states, or exist only in national border-control systems. A qualified legal check looks at all of them. A Google search looks at one.
The 72-hour protocol
Here is the sequence we walk our own clients through. Nothing in it requires special access — but all of it requires doing things in the right order, and not doing certain things at all.
Walk through this sequence once. Do not skip steps. Most mistakes are made by clients who jumped to Hour 60 before doing Hour 6.
Map the route, not just the destination
A direct Zürich → Dubai flight passes through two border systems. A Zürich → Istanbul → Dubai itinerary passes through three — including a transit state whose cooperation patterns with the issuing country may be very different. List every country whose airspace, airport, or immigration system you will touch, including technical stops, and rank them by risk.
Retain counsel in the departure and arrival jurisdictions
Not counsel "in Europe" — counsel physically reachable in the country you will be in when something happens. The lawyer who can intervene with Swiss border police at 02:00 is not the same lawyer who will handle a formal challenge weeks later. You may need both, and introductions take time you will not have at the gate.
Prepare the defensive file
Assemble — in a single encrypted folder accessible from your phone — a passport copy, prior refusal letters, correspondence relating to the underlying matter, proof of residence, proof of the purpose of travel, and contact details of counsel in every transit country. If you are stopped, the first thirty minutes determine the next thirty days. You will not have time to compose emails.
Reconsider the route
By this point you should know which transits are acceptable and which are not. A country that historically does not act on alerts from the issuing state is lower risk than a country with an active cooperation treaty and strong bilateral ties. We don't publish specific corridors — the map shifts — but your counsel should be able to give you a current read.
Decide — and communicate the decision
Go, reroute, or postpone. Whatever you decide, two or three trusted people should know your full itinerary, your counsel's contact details, and a check-in schedule. A missed check-in is how family and counsel know to escalate. Without it, a twelve-hour detention can become a seventy-two-hour silence before anyone realises something is wrong.
What not to do in the next 72 hours
Do not contact Interpol, SECO or any foreign authority directly from a personal email to "check your status". Do not call the issuing country's consulate. Do not post travel plans on social media. Each of these has, in cases we have seen, either triggered a response or materially narrowed the client's options.
We also strongly advise against filing a formal challenge in the 72 hours before travel. A filing of that kind creates a record and, in some cases, prompts a response from the issuing authority. If you are going to file, file before — or after. Never on the eve of boarding.
"The travellers who run into trouble are, almost without exception, the ones who treated the flight as routine until the boarding gate."
The question of voluntary disclosure at the border
A recurring question: should you volunteer information about a foreign case to border officers on arrival? The answer, almost without exception, is no. Answer what is asked, truthfully and briefly. Do not expand. Do not speculate about your own legal exposure in a language that is not your first. Any statement made at the border is admissible and, once made, cannot be unmade.
A 72-hour checklist you can print.
- Full route mapped — including every transit and technical stop
- Counsel retained in departure, transit, and arrival jurisdictions
- Encrypted document folder accessible from phone (passport, refusal letters, proof of travel purpose)
- Counsel contacts stored offline in multiple formats
- Two or three trusted people briefed with itinerary and check-in plan
- No public posts about the trip
- No direct contact with issuing-state authorities or consulates
- No formal challenges filed in the 72h pre-travel window
When 72 hours is not enough
There are situations in which the honest answer is: do not board. A client facing a confirmed high-risk alert from a country with active cooperation relationships across the route, travelling without counsel on the ground, with no defensive file, and on an itinerary with multiple screening points — that client should not be on the plane. No protocol substitutes for preparation time that was never taken.
But for the majority of urgent-travel cases we see — informed suspicion, no confirmed alert, reasonable route options — 72 hours is enough to reduce risk meaningfully. The clients who regret their decision are almost always the ones who convinced themselves the worry was "probably nothing" and boarded without asking.
If you're in that 72-hour window right now, the most useful thing you can do is stop guessing.
