Upgrade with Seatfrog

We are delighted to announce our brand new partnership with Seatfrog, an application that allows our guests with one Classic Room booked to bid for an upgrade to one of our Club Rooms.

An upgrade to a Club Room? That will do nicely!

Our Club Rooms include an en-suite with shower room, full breakfast in the morning, Club Car access and First Class Lounge access at the station where available. 

With the Seatfrog app Caledonian Sleeper guests who have booked one Classic Room can bid for an upgrade to a Club Room where available. 

 To get started, download the Seatfrog app, available on the App Store and Google Play.

On the app, enter your booking reference to check if you’re eligible to upgrade

View your trip and choose to place a pre-bid or buy it now to upgrade straight away

The auction opens 7 days before departure for a 4-day window, allowing you plenty of time to bid to win an upgrade

Drum roll please! If your bid wins, payment will be taken, and the upgrade will be sent straight to your phone. Please don’t throw away your original ticket as the upgrade will not be valid without it


What is Seatfrog?

Seatfrog is an app that allows guests to bid for an upgrade to a Club Room from a Classic Room if they have purchased a Classic Room ticket.

What ticket types can I upgrade to?

Guests with a valid and eligible Classic Room accommodation ticket can upgrade to a Club Room accommodation ticket. You can only bid if you have booked ONE classic room.

What routes are available?

All Caledonian Sleeper routes are available.

How does it work?

Enter your booking reference (CSW NUMBER ON YOUR BOOKING CONFIRMATION EMAIL or bottom of your ticket) on the Seatfrog app to get started and any eligible upgrades will display. Seatfrog will notify you 7 days before departure if there is an upgrade available and an auction will begin. You may place as many bids as you like before the auction closes 3 days before departure. If you win the auction, Seatfrog will process your payment and generate your ticket upgrade straight to your phone as a barcode in the app and via e-mail.

Can I pay for an upgrade without the auction?

Yes, there is an “Upgrade Now” option.

When do auctions run?

Auctions open 7 days before departure and run for 4 days.

Does it cost?

It is free to place bids. You only pay if you win!

How will I know when an auction is open?

Just make sure your Seatfrog app notifications are turned on and they will notify you when an auction opens.

Can I bid for multiple upgrades?

Sorry, only guests travelling with one room per booking are eligible to use Seatfrog.

Can I bid for an upgrade on a return journey?

You can bid on outward and return journey if you have booked one Classic Room for each leg of the journey.

How many bids can I place in an auction?

You may bid as many times as you like!

Can I see other people’s bids?

Seatfrog hide the details of yours and other people’s bids. You can see if you have been outbid.

Can I use Seatfrog in conjunction with my Flexipass?

Yes, you can bid on a single room if you hold a Classic Flexipass and have booked one room for your journey.

What happens if I have a bike reservation on my original ticket?

If you have a bike reservation on your original ticket, please give our helpful Guest Service Centre a call on 0330 060 0500. One of our Guest Ambassadors will create a standalone bike reservation for you so you can proceed with your Seatfrog bidding.

I have pre-booked Passenger Assistance with my original reservation, will it transfer to my upgraded Seatfrog booking?

Unfortunately, the Passenger Assistance booking will not transfer. However our Guest Ambassadors can easily book this for you. Please contact our Guest Service Centre via Live Chat or call 0330 060 0500. Have both your reference numbers handy.

Can I use Seatfrog in conjunction with Rail Staff Travel, discounted or free tickets?

Unfortunately, Seatfrog is not available with Rail Staff Travel, discounted or free tickets.

My bids have won the upgrade! Can I choose my new room?

Unfortunately, guests are not permitted to choose their own room.

How do I show the Train Manager my new ticket?

Simply show the barcode within the Seatfrog app or e-mail along with your original ticket.

What happens if my train is delayed or cancelled?

Seatfrog upgrades are eligible for Delay Repay compensation if a service is delayed by 30 minutes or more or cancelled.

My plans have changed and I can no longer travel. Can I get a refund on my upgrade if my original booking is a Flexible Ticket?

Unfortunately, a refund of the upgrade will not be permitted. You can, however, still claim a refund for your original ticket cost within the T&Cs of your original ticket.

What happens if there is a disruption?

Seatfrog will try to stop auctions if there is any expected severe disruption.

What happens if my phone runs out of battery?

Your upgrade is only valid if you can produce your barcode within the Seatfrog app along with your original ticket. Please make sure your phone is charged.
