What Is a Travel Consent Letter (and Why You Might Need One When Flying With Kids)

When you’re traveling as a family, most of the time everyone checks in together — and passports are enough.

This simple document can make a huge difference in ensuring your trip goes smoothly — and in some countries, it’s not just helpful, it’s legally required.

What Is a Travel Consent Letter?

A travel consent letter (also called a child travel consent form or parental authorization letter) is a signed document that proves a child has permission to travel from their parent(s) or legal guardian(s).

It’s most often needed when:

• A child travels with only one parent

• A child travels without parents (e.g., with grandparents, relatives, or a school group)

• Parents are divorced or separated

• The child’s surname is different from the accompanying adult

It helps border agents confirm that the trip has been approved by both parents, preventing issues related to custody or child safety.

Why Is It Important?

While many families never get asked for one, several countries require or strongly recommend a travel consent letter for minors.

Even if it’s not checked every time, it’s invaluable in preventing travel delays or misunderstandings — especially when crossing international borders.

Common Scenarios

Possible situations where a consent letter could be very helpful:

• A mother flies alone with her child --> Proves the other parent consents.

• A grandparent takes the child abroad --> Confirms both parents have given permission.

• Parents are divorced and share custody --> Demonstrates legal cooperation.

• Child has a different last name -->Helps immigration officers verify family connection.

Countries That Commonly Request Consent Letters

United States – recommended by border control

Canadastrongly recommended (government provides official template)

UK / EU – often requested when surnames differ

South Africamandatory for minors

Mexico, Brazil, Australia – may ask at immigration or check-in

In short: if your child is leaving their country without both legal guardians present, a consent letter is a smart move — even if the airline doesn’t mention it during booking.

What Should Be Included in a Consent Letter?

To be valid and effective, your letter should include:

• Full name and date of birth of the child

• Passport number of the child

• Names, addresses, and contact info of both parents/guardians

• Details of the accompanying adult (if applicable)

• Travel dates and destinations

• Statement of consent (“I authorize my child to travel with…”)

• Signatures of the non-traveling parent(s)

• Date of signature

• Optional but helpful: copy of the consenting parent’s passport or ID

• Optional: notarization (especially for international trips or shared custody)
