We strongly recommend that children travelling abroad carry a consent letter proving they have permission to travel from every person with the legal right to make major decisions on their behalf, if that person is not accompanying the children on the trip. For example, children travelling alone, with groups or with only one custodial parent should travel with a consent letter.
