Child luggage allowance

Kids travelling on a children’s ticket can take:

  • 1 piece of luggage (up to 85cm long)
  • 1 piece of hand luggage

Children under 4 years old

Kids under 4 can travel for free on Eurostar, provided they can sit on an adult's lap. Here's how it works:

  • Your child will need to sit on your lap throughout the whole journey.
  • If you want them to have their own seat you'll need to buy a child ticket (see below).


  • Travelling with more than one child under 4? They'll each need to sit on an adult's lap.
  • Travelling alone with two or more kids under 4? You'll need to take one on your lap and buy child tickets for the others.
  • Remember, kids of any age need their own passport to travel.

Fares for children over 4 years old

Special fares for kids aged 4 to 11 years old are available in Standard class.

Children,  aged 12 and over, are eligible for our youth fares.

Child facilities on board

Baby changing

All of our trains have baby changing facilities. If you'd like to sit nearby, simply log in and choose your seats once you've booked.

Family seating

If there's space, you can also choose to sit around a table so you can spread out the colouring books or get stuck into a game on the way.


Children's meals

Child-friendly options are available at Café Métropole, our onboard bar buffet.

We don't sell baby food but we're happy to help by warming it up at Café Métropole.

We’ll also be able to help you once your train arrives in its destination. If you only need assistance for part of thedeparture process, make sure you let our teams know so they can help you accordingly.

Unaccompanied children

Unaccompanied minors (up to the age of 18) will require additional documentation for travel. Please read the relevant section below and we also strongly recommend checking the latest government advice before you travel – from both the country you’re departing from, and the country you are travelling to.

Children under 12 years old:

Children under 12 must travel with a responsible person aged 16 or older.


Children under 12 to 15 years old (inclusive):

Children 12 to 15 (inclusive) can travel on their own, as long as they’ve got a fully completed Eurostar unaccompanied minor form. This must be signed by their parent or legal guardian (or by a responsible adult given consent by the parent or legal guardian) at the station in the presence of a member of the Eurostar team. The child will need to keep this signed form with them throughout their journey and show it to the onboard team if they’re asked. 

Please note: Children under 16 years of age cannot travel unaccompanied on the direct route between London or Ashford and Lyon, Avignon and Marseille, on our direct ski trains to the French Alps, or on our direct route between London/Brussels and the Netherlands.
