As of March 2026, the answer depends heavily on the destination, but for most international travel, it is extremely risky. Many popular tourist destinations (including most of Asia and the Middle East) strictly enforce a 6-month validity rule, meaning they will deny entry if the child's passport expires in less than 180 days from the date of arrival. While some European countries in the Schengen Area only require 3 months of validity beyond the intended departure date, airlines often apply the stricter 6-month rule at check-in to avoid liability for deported passengers. Even if a country legally allows entry with 3 months of validity, any unexpected flight delay or medical emergency could push the child past their expiration date, causing significant legal issues. In 2026, travel experts strongly advise renewing any child's passport if it has less than 7–8 months of validity remaining to ensure a smooth journey.
