UK train tickets to "London St Pancras International CIV" offer an extra level of protection for international train journeys.
These special fares, authorised by National Rail, ensure that your entire journey will be protected under international conditions of carriage.
This means that if your UK train is delayed you'll be guaranteed a place on the next available Eurostar and onward trains to your destination at no extra charge.
Tickets to "London St Pancras International CIV" also include travel on the London Underground (if necessary) to London St Pancras.
CIV fares are priced differently to normal tickets, and are only valid with proof of an onward Eurostar ticket.
Prices are usually slightly more expensive than non-CIV tickets for the same route, though they can sometimes be cheaper, especially during peak times.
