How do I find cheap train tickets from Prague to London St Pancras International?

If you’re planning a trip to Europe soon, our Trainline team of experts have put together some tips to help you find cheap tickets. Booking on the day in Europe is usually more expensive and costs can vary depending on the time of day, route or travel class.

1. Book in advance

The price of train tickets from Prague to London St Pancras International starts at § one-way for a Standard Class ticket if you book in advance. Most train companies across Europe release their tickets around three to six months ahead of time, so if you know the dates you want to travel, you may be able to find cheaper tickets.

2. Be flexible with your travel times

If you can, consider travelling outside of 'peak hours' (generally between 06:00 - 10:00 and 15:00 - 19:00 on weekdays) as many train companies increase their ticket prices during these commuter times.

3. Buy a rail pass

If you're visiting multiple locations on your trip, buying a rail pass can be cheaper than buying individual tickets. We're official retailers of Interrail Passes that are valid for travel within one country or multiple countries across Europe.

4. Choose a slower or connecting train

On some busier routes, you might have the option to take a slower or connecting train. It may take longer than some high-speed or direct services, but if you have some extra time on your hands, you might find a cheaper fare.

5. Look out for train ticket sales and discounts

Many train companies in Europe will often run sales on tickets throughout the year or offer discounts to senior/youth/group travellers, so keep an eye out!

6. Take a night train

Save on accommodation and use the night to travel by sleeper train to your next destination.

For specific information about how to get your hands on cheap tickets, check out our European train tickets hub.

§Some train companies may not offer any Advance ticket types or cheaper deals for early bookings. On rare occasions, train companies may choose to release special offers closer to the date on last-minute or late-release tickets. This is dependent on the individual train operating company you travel with.
