What is the cheapest way to get from Newcastle to London King’s Cross by train?

The good news is we don’t charge a booking fee and will match any other price you find and refund the difference, so your tickets will already be the cheapest around when you’re travelling to London King’s Cross. For an even better deal we’d recommend buying Advance singles rather than a Flexible ticket. It’s a great idea to set up a Ticket Alert so you know when these cheaper tickets are available.
