A travel consent letter is an international document used when a child is travelling with only one legal guardian, travelling alone, or travelling with an adult who is not their legal guardian. In many cases, it is a requirement for cross-border travel with minors.
Who may require a travel consent letter
A travel consent letter is commonly requested by:
- Airlines and check-in staff
- Border control and immigration authorities
- Tour operators, schools, and travel organisers
When it is required
A travel consent letter is especially important when a minor is travelling abroad:
- With only one legal guardian
- Without any legal guardian (travelling alone)
- With relatives, friends, a school group, or another responsible adult
This is a requirement in the vast majority of countries, and rules can vary by destination, airline, and route. It is always the traveller’s responsibility to confirm the applicable entry and boarding requirements for minors.
What can happen if you don’t have it
If a travel consent letter is not presented when requested, the trip can be delayed or stopped. For example:
- The airline may deny boarding at departure
- Border authorities may question the travel plans and refuse entry
- Additional checks can cause missed connections and significant delays
These rules exist to protect children, including reducing the risk of child abduction and preventing unauthorised international travel.
