7 Urgent Passport Checks for Brits Traveling Now

British travelers face critical new UK border rules effective February 25, 2026, as part of the Electronic Travel Authorisation (ETA) rollout. Dual British or Irish citizens cannot use an ETA or solely a foreign passport; airlines will deny boarding without a valid UK passport, Irish passport, or foreign passport with a Certificate of Entitlement to the Right of Abode. This ensures smooth entry via e-gates and avoids lengthy manual checks at the border.
