As titled, we are due to go on holiday to Spain on 4th June however our daughter turns 18 at the end of May, she currently has a child passport that is valid until 2026, Shes also now has dyed long hair, piercings and doesnt look the same as the picture. Should we think about getting her an adult passport or is the one we have fine, Just abit worried we'll get to the check in desk and be turned away or at worst get to Spain and be turned back by the Spainish passport control. Any thoughts?
