Seatfrog Discount Code Black Friday 2026 - 25% OFF

Seatfrog is a British travel company that runs a mobile app for rail passengers who would like a better seat without paying the full fare normally charged for it. The heart of the service is an upgrade auction: once someone holds a ticket with a participating operator, they can bid for the first class seat on their journey, and the app confirms whether the bid has won before the train leaves. Seatfrog also lists Secret Fares, discounted tickets sold at a set price rather than through bidding.

The business was started in London in 2015 by Iain Griffin and Dirk Stewart, and it works alongside UK train operators such as LNER, Avanti West Coast, Great Western Railway and CrossCountry. Everything happens inside the app, so payment is taken by card when a bid is placed and a winning upgrade is confirmed on the phone, leaving nothing to collect at the station. It suits travellers who already have a ticket and want more space and a quieter carriage for a modest extra amount.

Several cheaper routes sit alongside the auctions. A Senior Railcard held by a passenger aged 60 and over brings up to one-third off standard rail fares on eligible tickets. The refer-a-friend scheme gives the inviter and the friend £5 off a first class upgrade once the friend's first purchase goes through, while the app carries Secret Fares with up to 50% off standard tickets, first class auctions starting from £5, £5 referral credits and voucher codes that can be redeemed in the app. Points gathered on ticket purchases and upgrades can later become travel discounts and account credits.

Codes go into the discount code box at the Seatfrog checkout; deals need no code.
