For a stress-free journey on the Eurostar in 2026, you should arrive at the station at least 75 to 90 minutes before your scheduled departure. Unlike standard domestic trains, the Eurostar requires you to go through both security screening and border control (passport check) before you can enter the departure lounge. For Eurostar Premier (business class) passengers, the ticket gates close 15 minutes before departure, but a 45-minute arrival is recommended. For Standard and Plus passengers, the ticket gates close strictly 30 minutes before departure. If you are departing from major hubs like London St. Pancras or Paris Gare du Nord on a peak weekend or holiday, arriving 120 minutes early is safer, as queues for the French/UK border can be significant. Additionally, from February 2026, all non-UK/EU travelers may need to factor in extra time for the new European Entry/Exit System (EES) biometric kiosks, which can add 5–10 minutes to the check-in process for first-time visitors to the Schengen area.
