How many countries require proof of onward travel?

Onward tracks 57 countries and territories where evidence of onward or return travel is a documented entry condition, of which 20 check routinely (often at airline check-in). Every other destination has an answer page too — including what airlines can still ask on one-way fares. Enforcement varies by airline, route and officer — always confirm before you fly.

What happens if I don't have an onward ticket?

The airline can refuse to board you (they're fined if you're refused entry), and immigration can question or deny entry on arrival. A genuine exit ticket or a refundable fare fixes it — sort it before you leave for the airport.

Which airlines check proof of onward travel most strictly?

Budget carriers are the most proactive because they carry the fines — AirAsia, Batik Air, Cebu Pacific, Jetstar, Lion Air, Nok Air, Ryanair, Scoot, Spirit Airlines, VietJet Air, Volaris. Air New Zealand, Avianca, Copa Airlines, Fiji Airways, LATAM Airlines are also consistently reported on their strict-destination routes, and any carrier checks when the destination requires it.

Proof of onward travel, explained

Q: What is proof of onward travel?

Evidence that you'll leave the country you're entering — normally a confirmed onward or return flight with a verifiable booking reference (PNR). Airlines and immigration officers can check the reference in their systems.

Dozens of countries expect visitors to show a ticket out before they let you in — and it's usually the airline that checks, right at check-in, because they pay the fine if you're refused entry. Here's what counts as proof, where you'll be asked, and the cheap, legitimate way to sort it when you're travelling one-way.

Check your destination

Pick where you're going — and optionally your airline — to see whether you'll be asked for an exit ticket, who asks, and what counts.

What counts as proof

A confirmed onward or return flight with a verifiable booking reference is accepted everywhere. Some countries also accept bus, train or ferry tickets out. What does not work: an edited PDF or a screenshot of a booking that doesn't exist — officers type the reference into their system, and a fake can be treated as document fraud.

Travelling one-way on purpose? Ranked by safety: 1) a refundable full-fare ticket you cancel after arrival (bulletproof, briefly ties up the fare); 2) a cheap genuine exit flight to a nearby country (often US$20–50, real by definition); 3) a short-lived rented reservation — a real airline booking with a checkable PNR that expires on its own. Rentals are usually fine at airline check-in but riskier with strict immigration officers, and should never be used for a visa application.
