What the document is meant to show
The practical question behind an onward check is whether the traveller has a credible plan to leave. Airlines can check travel documents before boarding, and border authorities can ask questions on arrival. The evidence accepted for a particular journey depends on the destination, nationality, visa status and carrier procedures.
There is no single document that works for every route. Consult an official destination source and the operating airline before travel. IATA’s Travel Centre compiles passport, visa and health information used across the aviation industry, but the final decision remains with the relevant authority and carrier.
Common forms of onward evidence
A confirmed return flight is easy to understand, but it is not the only possible journey. A traveller may leave by a different airline, depart from another city, or continue by bus, ferry or train. Whether that evidence is accepted must be checked for the destination involved.
- Return flight to the point of origin
- Onward flight to a third country
- Open-jaw itinerary leaving from another city
- Accepted land or sea transport booking
- Residence or status evidence relevant to the onward destination
Build an itinerary that can be read quickly
The departure date should fall within the permitted or intended stay. Passenger names must match the travel document, and the onward destination should be one the traveller can enter. A ticket to a country for which the traveller lacks required permission may not answer the concern.
