Frontier Airlines Child Travel Documents for Canada: Parent Consent Guide

This is a summary of the current published rule. Confirm it on the airline’s own page before you travel.

This page is for families using Frontier Airlines on Canada itineraries with a child, including one-parent travel, shared or sole custody, travel with a non-parent adult, and ages 15–18 traveling alone to or from Canada.

Do not apply this Canada list to a Frontier flight that is not a Canada itinerary unless Frontier or the destination independently requires those documents.

Frontier Airlines publishes Canada-specific child-document guidance on its International Travel policy. That is a Frontier carrier instruction for Canada itineraries, not a worldwide Frontier parental-consent form.

Frontier does not accept children under 15 traveling alone. Ages 15–18 traveling alone to or from Canada currently need a travel-consent letter signed by a parent or legal guardian under Frontier's Canada guidance.

Canada and any other country on the itinerary may have their own entry or exit rules. Frontier's Canada list does not replace Government of Canada consent-letter guidance or a third-country exit process.

Review Canada Child Travel Consent for IRCC entry guidance, CBSA authenticity recommendations, and outbound travel.gc.ca consent-letter guidance.

Required under Frontier's current Canada guidance for the scenarios below. That status is Canada-specific. It is not a statement that Frontier requires the same authorization letter for every destination.

One-parent flying more generally is covered in Flying Internationally With a Child With One Parent. Non-parent adults are also covered in Flying With Grandparents, Stepparents or Another Adult.

Frontier's Canada consent-letter guidance for ages 15–18 traveling alone is still a parental travel-authorization letter, not an Unaccompanied Minor custody form of the JetBlue type. Frontier's under-15 traveling-alone restriction is a carrier acceptance rule.

ONE PARENT: the traveling parent should have the child's passport, a copy of the child's birth certificate, an authorization letter in English signed by the non-traveling parent, the absent parent's address and phone number, and a copy of the absent parent's signed passport or national identity card.

SHARED CUSTODY: current guidance includes legal custody documents, an authorization letter from the non-traveling parent, contact details, and an absent-parent ID copy.

SOLE CUSTODY: Frontier identifies documentation such as custody documents, a birth certificate identifying one parent, or a death certificate of a deceased parent.

LEGAL GUARDIAN / ADOPTIVE PARENT: use guardianship or adoption documentation as applicable. If two guardians or adoptive parents exist and only one travels, signed authorization is part of the guidance.

NON-PARENT ADULT: written parent/guardian permission, including parent/guardian address, phone number, and signed ID or passport copies.

AGES 15–18 TRAVELING ALONE TO/FROM CANADA: a travel-consent letter signed by a parent or legal guardian containing travel authorization, signer contact information, and information for the adult responsible for the child in Canada.

Frontier does not publish a general rule requiring every parental consent letter to be notarized. A Canada or other border requirement may still apply.

Remote online notarization is not applicable and is not expressly stated unless another applicable requirement calls for notarization. Do not start a notary session based solely on Frontier's Canada authorization-letter list.

Frontier's Canada guidance currently contemplates copies of certain ID and birth-certificate documents alongside the signed authorization letter. Confirm the live International Travel page for the format Frontier will accept at check-in.

Citizenship, dual nationality, and residency can add a Canadian or other government rule on top of Frontier's Canada list. Frontier's carrier instruction is not the only possible document owner.
