Has anyone advice on what documentation is needed when flying with a child that is not a relative, without their parents. My friends daughter has asked if I would take her daughter with me when I go to visit her mother (the childs grandmother), the mother would be bringing the child back to the UK, she is flying out 2 weeks later so it is only from the UK that I need to know what is required, she would supply a letter but I am wondering if that is sufficient.
