Mobile Tickets and etickets aren’t valid for the London Underground so if you book a journey with us that travels through London on the tube, we won’t offer you this option.
However, if your ticket says ‘any route permitted’, you’ll have the flexibility to travel to your destination on a different route to the one you originally chose when you booked.

Please bear in mind that if you’re travelling with a Mobile Ticket or eticket and decide to take a route that goes via a London Underground station, your Mobile Ticket or eticket won’t be valid for this part of the journey. You’ll need to buy a separate ticket for the London Underground, or use an Oyster Card or contactless payment option.
