Unlike air travel, there is no checked baggage on the Eurostar in 2026. You are responsible for carrying your own luggage onto the train and stowing it yourself. Each carriage is equipped with large luggage racks near the entrance doors for heavy suitcases and smaller overhead racks above the seats for backpacks and carry-ons. There is no strict weight limit, but you must be able to lift and carry your bags yourself, as porters are generally not available. The standard allowance for 2026 is two large suitcases (up to 85cm long) and one small piece of hand luggage per adult. For those in Business Premier, there is slightly more flexibility, but the "self-stow" rule remains. One major advantage is that you keep your bags with you, meaning there is zero wait time at a luggage carousel upon arrival in London, Paris, or Brussels. However, it is highly recommended to use the racks closest to your seat to keep an eye on your belongings during the journey.
