As of early 2026, EasyJet’s policy regarding young travelers is very strict: children aged 15 or under are not permitted to travel unless they are accompanied by an adult who is at least 16 years old. EasyJet does not provide an "Unaccompanied Minor" service, which means there are no staff members assigned to supervise children during the flight or at the airport. If a child under 16 is not accompanied by a 16+ year-old companion on the same booking, they will be refused boarding at the gate. For domestic flights, children under 16 typically do not need to show a passport (provided their adult companion can vouch for them), but for international travel, everyone—including infants—must have their own valid passport. If you need a child to fly alone, you would need to book with a full-service carrier like British Airways or Lufthansa, which offer dedicated, paid supervision services for minors.
