If your schedule allows flexibility, choosing off-peak hours for your trip from Portsmouth & Southsea to London can result in significant cost savings. In most cities and large towns, off-peak hours usually start at 09:30 from Monday to Friday. In other areas, they typically begin at 09:00.

Split Tickets to save an average extra 30%

Splitting your tickets involves purchasing separate tickets for different segments of your journey instead of a single ticket for the entire trip. This method is legal and can often result in cheaper fares. For example, if you are travelling from A to B, you might discover that buying a ticket from A to C, and then another ticket from C to B, is more economical than purchasing a direct ticket.
