Do You Need an Onward Ticket When You Leave by Land?

Fly into Amsterdam planning to train onward to Berlin and out from there, and you'll hit a snag most guides skip: check-in agents and immigration systems are built to expect a flight, not a rail ticket. A dummy ticket, also called an onward ticket, is a real flight reservation booked to show proof of onward travel without paying for the seat. If your actual plan involves a bus or train, that gap is exactly where a dummy ticket earns its keep.

Why leaving by land doesn't solve the problem

It's tempting to think "I'm not flying out, so this doesn't apply to me." Unfortunately the check usually happens before you ever reach the land border. Airlines use IATA's Timatic database at check-in to confirm a passenger meets the destination's entry conditions, and in a lot of cases that includes evidence of onward or return travel. Timatic works off flight and visa data, not bus timetables, so a printed intercity coach ticket often just doesn't register as something the agent can verify in the system.

Government travel advice pages reflect the same gap. Several country entries on gov.uk's foreign travel advice remind visitors they may need to show evidence of their onward or return travel plans, without specifying that it has to be a flight, which leaves plenty of room for an airline's own check-in software to default to what it knows: PNRs.

Where the check actually happens

The point of friction is almost never the land crossing itself. It's the check-in counter for the flight that gets you into the region in the first place. Airlines carry legal and financial responsibility for passengers who get turned away at the destination, so gate agents lean on document checks to avoid that liability. That's the moment a coach ticket from Bangkok to Phnom Penh, or a rail pass covering Amsterdam to Berlin, tends to fall short: it's not in a format the check-in system recognises, and the agent has no easy way to confirm it's real.

Once you've actually landed and cleared immigration, land border posts further down the route are a different story. Officers on foot or bus crossings are usually focused on your passport and visa status rather than re-checking onward proof, since there's no airline enforcing it at that point. Coverage varies by country and by officer, which is part of why My Dummy Ticket's piece on the Thailand border run found land crossings noticeably more relaxed than airport arrivals.

Three ways to cover yourself without buying a flight you won't use

Backpackers who know they're leaving overland generally land on one of three approaches. Here's how they stack up:

A dummy ticket through a service like My Dummy Ticket exists specifically for the first scenario most travellers actually face: you need a real, checkable PNR at the counter, not a flight you're going to fly.

Does the departure date on the ticket actually matter?

Yes, and this is where people trip up even after they've booked something. The reservation needs a departure date that's plausible given your visa or entry stamp, not just any date in the future. If you're entering on a 30-day visa exemption and your onward ticket shows a flight two months out, an alert agent may notice the mismatch even though the ticket itself is real. Match the booking to the length of stay you're actually entitled to, and if your land route means you genuinely don't know your exit date yet, book something inside the permitted window rather than guessing long.

What if you're asked for proof again at check-in for a connecting flight

It happens more than people expect on multi-leg overland routes. Say you fly into Lisbon, train around the Schengen area for three weeks, then need to fly out of a different city. Each airline you deal with runs its own check, so a reservation that satisfied the first check-in desk doesn't automatically carry over. If your actual exit plan changes partway through the trip, whether that's a new departure city or a different date, it's worth confirming your onward proof still lines up with the new outbound flight and its check-in requirements, not just the original entry point. For a refresher on what a dummy ticket actually is and how it differs from a paid reservation, My Dummy Ticket's explainer on dummy and onward tickets covers the basics in more depth.

Digital nomads who never book a return flight at all

For long-term travellers moving overland for months at a time, this isn't a one-off puzzle, it's a recurring one. Someone hopping by bus from Colombia through Ecuador and Peru, or working their way overland across Southeast Asia, might cross a dozen borders without ever holding a genuine return flight home. Each entry still runs into the same check-in logic described above, so the practical workflow most nomads settle into is booking a short-validity dummy or onward ticket for every flight leg where a physical border crossing follows by land, rather than trying to hold one long-haul return fare that covers the whole trip.

It's a small habit. Book it, screenshot it, move on. The reservation only has to survive the one check-in desk and the one immigration booth it's meant for, not the rest of the itinerary. Treating each flight entry as its own separate onward-ticket decision, instead of trying to solve the whole multi-month route with a single ticket, is what keeps the admin manageable for people living out of a backpack for half a year or more.

The short version

Planning to leave by bus, train, or ferry doesn't remove the need for an onward ticket. It just moves the pressure point earlier, to the check-in counter for the flight that gets you there. A dummy ticket that satisfies that one specific gate is usually all you need, at a fraction of the cost of holding a real flight you'll never board. Book a dummy ticket before your next overland trip and skip the guesswork at check-in.
