Do You Need An Onward Ticket For Argentina? 2026 Rules

Planning a trip to Argentina on a one-way ticket? This guide explains whether you need proof of onward travel, who actually checks it, and what else you need to enter in 2026.

The Short Answer

It can be asked for. Argentine immigration can request a return or onward ticket, and since 2025 visitors also have to declare health insurance.

Visa: Visa-free for US, UK, EU, Canadian, Australian and many other passports
Length of stay: Up to 90 days, extendable once for 90 more at Migraciones
Before you travel: A sworn declaration of purpose and health insurance under Decree 366/2025

Who Checks: The Airline Or Immigration?

Immigration officers decide. They can shorten your stay or refuse entry if they believe you are living in Argentina as a tourist. Airlines may also check onward travel and insurance before boarding.

Airlines check because they can be fined, and must fly you back at their own cost, if you are refused entry. That is why the check-in desk is often stricter than the border.

Entry Rules For Argentina In 2026

Decree 366/2025 requires non-resident visitors to declare that they hold health insurance for their stay. A June 2026 court decision created some legal uncertainty about the rule, so check current instructions before you travel and carry your policy certificate anyway.

Repeated border runs are now scrutinized more closely, and officers can grant fewer than 90 days.

What Counts As Proof Of Onward Travel?

Any confirmed booking that shows you leaving Argentina within your permitted stay, to a country you are allowed to enter. Common options are:

A return flight home
A flight to another country
A bus, train or ferry ticket out of the country, where accepted
A verifiable flight reservation with a booking reference (PNR)

A ferry ticket to Uruguay, a bus ticket to Chile or a flight home all count. See our guide to verifiable reservations versus dummy tickets for what airlines can check.

If You Do Not Want To Buy A Ticket Yet

Many travelers do not know their next stop. Instead of buying a full fare you might not use, you can get an onward flight reservation from Fast Onward Tickets in minutes and show it at check-in and at the border. Our complete guide to proof of onward travel covers every option.
