The British Airways Club has rolled out a limited-time Balance Boost promo that lets you pay cash to multiply many of the Avios you earned in 2025 and early 2026 by up to 500%.
At the best Balance Boost pricing, you’re effectively buying Avios for around 1.22–1.25 cents per point (USD), or roughly 1.6–1.7 cents per point (CAD).
That’s a big step down from the usual about 2.3 cents per point (USD), which is roughly 43 Avios per US dollar when you buy Avios outright.
Under this promo, you’re landing closer to 83 Avios per US dollar, which is about a 90% “bonus” equivalent in buy-points promo terms, and much richer than the usual 40–50% sales.
However, there are some important caps and quirks in the fine print, so this is very much a deal where the structure matters just as much as the headline.
Boost British Airways Avios by up to 500%
Through February 6, 2026 at 17:00 GMT, eligible members of The British Airways Club can use cash to boost the Avios they earned from qualifying transactions between January 1, 2025 and February 6, 2026.
In simple terms, Balance Boost lets you take an individual Avios-earning line item and pay to add extra Avios on top. Under this promo, you can choose a 500% boost, which means you’re adding five times the original earning amount to your balance for a fixed cents-per-point price.
You access the offer by logging in to your British Airways Club account, navigating to the Boost Avios page, and then selecting which individual transactions you want to boost and at what multiplier.
For Canadians, the key point is that the usual earning sources do count as eligible activity when they post to your BA account within the promo window.
Regular spending and welcome-bonus Avios from the RBC® British Airways Visa Infinite‡ Card show up as individual line items and can be boosted.
RBC Avion points and American Express Membership Rewards points transferred to Avios each land as their own transactions, and as long as those credits posted between January 1, 2025 and February 6, 2026, they should appear as eligible entries you can multiply with Balance Boost.

The terms exclude a few things: previously bought Avios, Avios that were gifted or transferred by another member, certain bonus postings, and some partner exchanges.
Those won’t show on the Balance Boost page, so if you don’t see a transaction there, it’s not in play.
Pricing and Limits on the 500% Boost
Avios uses a separate pricing table for Balance Boost. For accounts priced in US dollars, the first 300,000 boosted Avios per membership year are generally charged at about 1.22–1.25 cents per point (USD), or around 1.65–1.7 cents per point (CAD).
For comparison, the usual non-promo “buy Avios” rate works out to around 2.3 cents per point (USD), and prior “buy Avios with a bonus” sales have often landed in the 1.6–1.7 cents per point (USD) range at their best.
Dropping from roughly 2.3 cents per point down into the 1.22–1.25 cent range is what makes this promo behave like a roughly 90% bonus equivalent versus the standard purchase price.

Crucially, that 300,000 boosted Avios cap refers to the number of extra Avios you buy via Balance Boost, not your original earnings.
With a 500% boost, you’re buying five times the underlying amount. That means the true sweet spot is if you can select eligible activity that totals close to 60,000 Avios and boost it at 500%.
If you go beyond 300,000 boosted Avios in a membership year, any additional boosted Avios are charged at a higher rate that’s similar to the standard buy-Avios cost, and the deal quickly stops being interesting.
Balance Boost also operates on each individual earning line item, not your total balance, which leads to the slightly awkward big-transaction problem.
If you have one chunky entry of 100,000 Avios, only part of that chunk can benefit from the 500% boost at the good price, because of how the system caps and counts boosted Avios against your 300,000-point discounted allowance.
On the other hand, if your Avios earning across 2025 and early 2026 is made up of a bunch of medium-sized transactions, such as monthly RBC® British Airways Visa Infinite‡ Card spend postings, separate Avion transfers, and separate Amex Membership Rewards transfers, it becomes much easier to pick and choose a basket of transactions that add up close to 60,000 eligible Avios and fit neatly under the 300,000-point cheap-rate cap. That’s where you squeeze out the best value from this promo.
Conclusion
The current British Airways Balance Boost 500% promo is one of the more interesting Avios deals we’ve seen in a while. At around 1.65–1.7 cents per point in (CAD), you’re buying Avios below our 2-cent valuation and getting close to a 90% “bonus” equivalent compared to the usual non-promo buy-Avios rate.
Although this is a strong offer from a cents-per-point perspective, it’s still not a reason to buy Avios “just because”.
Only boost your balance if you have a clear redemption goal in mind and a plan to use those points in the near to medium term – otherwise, you’re simply tying up cash in a currency that can devalue at any time.
