Can airlines deny boarding without an onward ticket?

Why airlines check your documents

When a country refuses entry to a passenger, the airline that brought them usually has to take them away again. US law, for example, says a passenger ordered removed on arrival is removed immediately on an aircraft of the airline they arrived with (8 U.S.C. §1231(c)).

So airlines check documents before you fly. IATA says its Timatic database helps airlines “avoid immigration fines”, and that it’s used to check the travel documents of over 700 million passengers a year.

When a missing onward ticket becomes a problem

It depends on where you’re going. Where the rules make a return or onward ticket a condition of entry, an airline can refuse to board you without one. Examples from our checker:

• New Zealand: you must be able to show a paid ticket out at check-in for your flight.
• United States: Visa Waiver Program visitors must hold a round-trip ticket by law.
• Philippines: a return or onward ticket is a condition of visa-free entry.
• Indonesia and Panama: a return or onward ticket is part of the entry requirements.
