How does Seatfrog upgrade pricing work?
Upgrade pricing depends on whether you choose to bid in an auction or use Upgrade Now.
All upgrade prices are the same for every customer.
Railcards do not apply.
Child upgrades are the same price as adult upgrades.
There is one upgrade price for all passengers.
A £3 platform fee per ticket is added to all winning bids and Upgrade Now purchases.
Auction pricing
In an auction, the upgrade price is determined by bids from other travellers on the same train.
Bids increase in set increments above the current highest bid.
The price rises as other customers place higher bids.
You will only be charged if you win.
When you place a bid, you agree to pay up to your bid value if you win.
Opening price (reserve price)
Each auction starts at a minimum opening price.
This price is set in advance based on:
Train capacity
Seat availability
Journey duration
Once a bid is placed above the opening price, upgrades become available to win.
Bidding for multiple upgrades
If you select more than one upgrade, your bid is charged per seat.
Your total cost = bid amount × number of upgrades selected.
For example:
£15 bid × 2 upgrades = £30
£15 bid × 3 upgrades = £45
Each time you increase your bid, the increase applies to every upgrade selected.
You will only be charged if you win.
