The way Seatfrog auctions work is that we are initially allocated several seats to offer as First Class upgrades. But as people return to travel and with social distancing still in place, services can quickly become busier than expected. When this happens, availability is reduced, and an auction may close early. When this happens the auction summary will update to show 'All Seats Sold Out' or 'No Upgrades Available" depending on your device. This means that the initial allocation of seats are no longer available to Seatfrog.
