Well, everyone except Queen Elizabeth.
As it turns out, the British monarch is the one person in the world who doesn’t need a passport to fly. According to the royals’ official website, the first page of a British passport says the following:
“Her Britannic Majesty’s Secretary of State requests and requires in the name of Her Majesty all those whom it may concern to allow the bearer to pass freely without let or hindrance and to afford the bearer such assistance and protection as may be necessary.”
And because the passport is issued in the Queen’s name, “it is unnecessary for The Queen to possess one.”
The exception doesn’t apply to any other members of the royal family, though. Prince Philip, the Duke of Edinburgh, as well as Prince William and Prince Harry, all must carry a passport in order to leave the country.
Still, it’d be unfair to say the royals always follow the rules. These are the 12 times the royal family broke its own protocol.
