An onward ticket is proof that you will leave the country you are entering: a flight, bus, train or ferry ticket out of it, dated within the stay you are allowed. Countries ask for it mostly from visitors who come without a visa or with a visa on arrival, and airlines check it before you board, because an airline that brings a passenger who is refused entry has to take them back. Below are the rules of 8 destinations as their own government websites state them, what counts as proof, and what to do when your plans are not fixed.
- What counts: a ticket out of the country to any other country you are allowed to enter, by air, land or sea, leaving within your permitted stay.
- Who checks it: the airline at check-in, and the immigration officer when you arrive.
- Ticket or reservation: New Zealand says the onward ticket must be paid for. The other rules below say "ticket" without saying whether it has to be paid, so the airline and the officer decide.
- Timing: a reservation without a ticket is held only until the airline's time limit, so it must still be active on the day you fly in.
What is an onward ticket?
An onward ticket, also called proof of onward travel, shows that you have a way out before you are let in. It can be:
- a return ticket to your home country;
- a ticket to a third country, not the one you are entering;
- a bus, train or ferry ticket across the border: Thailand's rule names "air, train, bus, or boat tickets".
Two details are easy to miss. The trip out has to leave within the stay you are given: a visa waiver visitor to New Zealand must leave within 3 months of arrival, or 6 months for UK citizens. And the next country has to let you in: New Zealand asks for a ticket "to a country you have the right to enter", and if that country has its own onward rule, you may be asked to show the ticket out of it too.
The reason behind the rule is practical. Visa-free entry is granted for a limited stay, and a planned exit shows you will keep to it. If you are refused entry, the airline that brought you has to fly you out: in the Schengen area, the border authority orders the carrier to take the person "without delay" to the country they came from or to another country that will admit them (Schengen Borders Code, Annex V). That is why airlines check before you board.
Which countries ask for proof of onward travel?
These are the official rules of 8 popular destinations, quoted from their government websites and checked on 4 November 2026. Entry rules change, so open the source before you travel.
| Destination | Who it applies to | What the official rule says |
|---|---|---|
| Thailand | Visitors under the visa exemption, which is 30 days for most nationalities since 15 September 2026 | Proof of planned travel ("confirmed air, train, bus, or boat tickets") to leave Thailand within 30 days of arrival; without it, you need a visa before you travel.

The question can come up on other routes too, because airlines check every passenger's documents against IATA's Timatic database: IATA says it is used for more than 700 million passengers a year. To see whether you need a visa at all, check the visa requirements for your passport and destination.
Is an onward ticket an actual flight ticket?
It depends on the rule. A ticket is paid and has a 13-digit ticket number. A reservation is a booking in the airline's system with a booking code (PNR) and no ticket number yet: see PNR number vs ticket number.
- New Zealand is explicit: the onward ticket must be paid for before you travel. A reservation does not meet that rule, so buy a refundable fare instead.
- The other rules in the table say "ticket" or "confirmed ticket" and do not say whether it must be paid. The check-in agent and the immigration officer decide what they accept, so if you are unsure, ask your airline before you fly.
Not the same thing: a sample ticket is a document laid out like a ticket, with no booking behind it. It is for travel plans, drafts and mock-ups, not for anyone who checks the booking, so it is not proof of onward travel.
Onward ticket for a visa application
A visa application is a different check: the consulate looks at your travel plans before you travel. For a Schengen visa, the EU's Visa Code lists a "reservation of or return or round ticket" among the documents on your intention to leave, so a reservation is enough unless your consulate's checklist asks for a paid ticket. Our Schengen visa page quotes the EU's document lists by country, and the guide to flight reservations for visa applications covers what consulates usually accept.
If the same trip also needs proof of onward travel at the airport, keep the dates consistent: the reservation, the hotel confirmation and the cover letter should all show one trip.
Who checks your onward ticket?
- The airline, before you board. Immigration New Zealand tells visitors that the airline may ask to see the ticket out at check-in. This is where most travellers are asked.
- Immigration on arrival. The officer may ask for it at passport control. New Zealand can refuse entry to a visitor who cannot show evidence of onward travel or the money to leave, and Thailand asks visitors without proof of onward travel to get a visa before they come.
- Visa centres, when an application needs a travel plan with all the flights.
Is an onward ticket legal?
Two questions hide behind this one.
Can a country or an airline require it?
Yes. Every country sets its own entry conditions, and proof that a visitor will leave is a common one, written into the rules in the table above. Airlines enforce it because they carry the cost of a refused passenger. "It's just an airline money grab" is a myth: the rule comes from the destination country.
Is it legal to use a flight reservation as an onward ticket?
Yes. A reservation made with an airline in your name is a real booking. Holding it while you travel and letting it lapse is how airline reservations work: when the hold ends, the airline cancels it and you owe the airline nothing. Where a rule asks for a paid ticket, as New Zealand's does, a reservation does not meet it.
What is not legal is presenting a document as a booking when it is not one: an edited confirmation, an invented booking code, or a sample itinerary passed off as a reservation. That is false information to an airline or a border officer, and it can end with denied boarding, refused entry or a ban.
How long does an onward ticket reservation last?
As long as the airline holds it. Every unpaid booking has a time limit for issuing the ticket, and when it passes, the airline cancels the booking. From the reservations we make every day, the hold depends most on how far away the booked flight is:
| Flight in the reservation | How long the hold usually lasts |
|---|---|
| Within the next 5 days | 15 minutes to a few hours |
| 5 to 14 days away | A few minutes to a couple of days |
| 15 days or more away | A few hours to a couple of weeks, sometimes a month |
These are likelihoods, not promises: the airline decides, and it can cancel an unpaid booking earlier than usual. Our guide to temporary flight reservations shows the same on a calendar.
For an onward ticket this means:
- The onward flight is usually weeks after your arrival, so it often falls into the longest holds, but even then a hold of a few hours is possible.
- Order it shortly before you fly in, the day before or the same day. The checks happen at check-in for that flight and at the border, so that is when the booking has to be active.
- Check it before you leave for the airport: open it on the airline's website with the booking code and your surname (how to check a PNR online).
- After you have entered the country, the reservation has done its job. When the hold ends, the airline cancels it.
How to get an onward ticket
- A refundable ticket. Buy a fully refundable fare and cancel it after you arrive. It meets every rule in the table, New Zealand's included, but you pay the whole fare upfront and wait for the refund. Read the fare rules for cancellation fees first.
- A flexible ticket. A fare that allows date changes: book a far date and move it when your plans are clear, paying the change fee if there is one.
- A cheap ticket you may use. A low-cost flight or bus to a neighbouring country is a real ticket. If your plans change, you may lose what you paid for it.
- A flight reservation. A booking in your name held in the airline's system, with a code that can be checked, for a service fee instead of a fare. It does not meet a rule that asks for a paid ticket.
- A bus, train or ferry ticket. If you will leave overland, a ticket to a neighbouring country counts under rules like Thailand's. Some check-in agents expect a flight, so ask your airline whether it accepts one.
Need proof of onward travel for your trip? A KeyFlight onward flight reservation is a real booking in your name, with a booking code you can check on the airline's website. It usually arrives in about 5 minutes; if the automatic booking does not go through, it is made by hand and sent within 24 hours. How long the airline holds it depends on the airline and the flight date, so order it close to your flight.
Tips before you fly
- Pick the right date. The onward trip must leave within the stay you are allowed, for example within the visa-free days.
- Make the route plausible. A flight home or to a neighbouring country reads better than a random route.
- Think one country ahead. If your next country needs a visa or has its own onward rule, you may be asked for that too: Singapore lists "entry facilities, including visas, to the next destination".
- Match the passport. Names on the booking must be spelled as in the passport.
- Keep it offline. Have the PDF on your phone and a printed copy: airport Wi-Fi fails at the worst moment.

Questions people ask
Is an onward ticket the same as a return ticket?
A return ticket is one kind of onward ticket: it takes you back home. A ticket to any other country you can enter counts too, as long as it leaves within your permitted stay. The US is stricter: a Visa Waiver Program traveller's trip out cannot end in Canada, Mexico or an adjacent island unless the traveller lives there.
Does an onward ticket have to be a flight?
Not under every rule. Thailand names train, bus and boat tickets, and New Zealand accepts a cruise ship itinerary. Airlines may still expect a flight at check-in, so ask yours before you travel overland.
Do I need an onward ticket if I have a visa?
Sometimes. Costa Rica's guidelines list a ticket out for every foreign visitor, and the Philippines' arrival checklist names it for tourists. With a visa, follow its conditions and ask your airline.
What happens if I cannot show one?
The airline can refuse to let you board, and the officer can refuse entry. New Zealand names missing evidence of onward travel as a reason to refuse entry permission, and Thailand asks visitors without it to get a visa first.
How much does an onward ticket cost?
It depends on the option. A refundable fare costs the full fare until the refund arrives. A reservation costs a service fee, not a fare. A bus ticket to a neighbouring country can be the cheapest real ticket.
Summary
Onward ticket rules come from the destination country, and airlines check them because they pay for refused passengers. Check the official rule for your destination: where it asks for a paid ticket, as in New Zealand, buy a refundable fare; elsewhere, a real reservation in your name, ordered close to your flight, is a common answer. A document that only looks like a booking is not proof of anything. Travel agents who already have the booking in Amadeus, Sabre, Galileo or Worldspan can turn it into a readable itinerary for the client with the PNR converter.
