Seatfrog, a train ticketing app, has introduced a new Secret Fare ticket feature, providing commuters in the East Midlands with up to 50% off on selected trips. The secret fare feature allows passengers to secure the best fares on select East Midlands Railway routes provided they have flexible travel times. Customers can reserve their Secret Fare tickets when services open for reservation, generally three months prior to the journey, and up until two days before the journey date. Unlike other pre-booked tickets, customers choose a travel slot in the morning, afternoon or evening, but the exact travel time is allocated 24 hours before the journey.
