How to book cheap train tickets from Knebworth to Portsmouth & Southsea

Traveling in off-peak train times

We recommend buying train tickets from Knebworth to Portsmouth & Southsea during off-peak hours. These times are usually before 06:30, between 09:30 and 16:00, and after 19:00 on weekdays, as well as all day on weekends and bank holidays. Choosing Off-Peak train tickets means benefiting from cheaper fares and less crowded trains, making your journey more enjoyable.

Get 1/3 off with a Railcard

You can choose a Railcard to help you save up to 1/3 on fares from Knebworth to Portsmouth & Southsea for various reasons, such as your age (including the 16–25 Railcard or Senior Railcard) or options geared towards group travel (Family & Friends Railcard and Two Together Railcard). Discover more here.

Split tickets to save an average extra 30%

Splitting tickets is a perfectly legal practice that involves purchasing separate, cheaper tickets for different segments of your journey on the same train instead of a single ticket for the entire trip. For example, if you are travelling from Knebworth to Portsmouth & Southsea, you might discover that buying a ticket from A to C, and then another ticket from C to B, is more economical than a direct ticket.

Book in advance to save an average of 61%

Advance Tickets are usually released up to 12 weeks before the travel date and can be significantly cheaper than tickets purchased closer to departure. By planning your trip from Knebworth to Portsmouth & Southsea ahead of time and securing your tickets early, you can save up to 61% on the cost of your travel.

Travel in a group to save 1/3

If you are traveling in a group of three to nine people, take advantage of group travel discounts, offered by most train companies, for a discount of up to 1/3 on standard fares. This can make traveling from Knebworth to Portsmouth & Southsea more affordable for families, friends, or colleagues planning a trip together.
