For years, British Airways has teased passengers with the possibility of a last-minute upgrade at the airport. Now, the airline has formalised it. You can officially bid for a BA upgrade online before your flight – a digital auction that lets you name your price for that coveted seat in Premium Economy, Club World, or even First on rare occasions. Here’s how it works, what’s worth knowing, and when it’s best avoided.

How the BA Upgrade Bidding Works
British Airways has partnered with Plusgrade, the company behind many airlines’ upgrade auctions. After you book, you may receive an email inviting you to make an offer. Alternatively, you can check eligibility directly on the Plusgrade site by entering your booking reference and last name. If your flight qualifies, you’ll see a slider with a minimum and maximum bid range – drag it to whatever you’re willing to pay.
The system takes your payment details upfront, but you’ll only be charged if your offer is accepted. You can modify or withdraw your bid up until roughly six hours before departure, provided BA hasn’t already accepted it. If successful, you’ll get the upgraded seat, access to any applicable lounge, and the higher cabin service, but your original fare rules still apply – meaning your baggage allowance usually doesn’t change.
How BA Decides Whether You Win
There’s no fixed threshold that guarantees success when you bid for a BA upgrade. The outcome depends on how many seats are left, what others have bid, and the airline’s appetite for selling discounted seats versus keeping them for frequent flyers. Typically, results come through between 48 and 24 hours before departure, though last-minute decisions happen too.

Because this is essentially an auction, a “strong” bid doesn’t mean much if the cabin fills up through normal ticket sales. Routes with lighter demand, like off-peak transatlantic flights, tend to see more accepted bids than premium-heavy routes to places like Los Angeles or Dubai.
Is It Good Value?
That depends on what you bid and what cabin you’re moving into. Some travellers have reported bid ranges higher than BA’s fixed “Upgrade with Money” prices in Manage My Booking, which makes the whole exercise feel a bit like a game of airline roulette. The best wins tend to be those modest jumps – say, from World Traveller to World Traveller Plus – where the seat and meal service improve dramatically without spending a fortune.
If you’re bidding on a business class upgrade – Club World – be careful to check whether you’re being offer the newer Club Suite product and not the older Club World ying-yang seats that still feature on older cabins and most of the long-haul departures from Gatwick.

Just remember: even if you win, you won’t earn extra Avios or Tier Points, because your ticket technically remains in the original fare class. So if you’re chasing status, it might be smarter to use Avios or pay the official upgrade price instead.
BG1 Verdict
Bidding can be a fun way to snag an upgrade when prices are steep or cabins are half-empty. If you’d happily pay that amount anyway, go for it. If you’re treating it like a lottery, lower your expectations. The key to success when you bid for a BA upgrade is knowing what the higher cabin is really worth to you – and resisting the urge to overpay just because the slider says “very strong”.
