BA May 2026 Avios Sale: A Trap for Short-Haul, A Steal for Asia

British Airways has launched a 40% bonus on purchased Avios for the next five days, and the marketing emails are already flooding in. At Points Uncovered, we see these sales multiple times a year. They always promise the world, but the reality is deeply polarized. If you are flying to Asia in a premium cabin, this sale is a license to print money. If you use these bought points for a quick summer trip to Spain, you are getting fleeced.

Here is the thing about buying points in May 2026: cash fares are painfully high, but award availability has shifted. You have to know exactly what you are doing before you hand over your credit card. Let’s break down the exact maths of this promotion so you know whether to open your wallet or ignore the email.

The exact maths of the May 2026 Avios sale

Maxing out the current 40% bonus yields 280,000 Avios for £3,215, pegging your cost at exactly 1.15p per point. This is the baseline number you need to keep in mind for every redemption calculation over the next five days. If you buy the maximum allowance of 200,000 Avios, the 80,000 bonus drops into your account instantly.

The catch is the tiered bonus structure. British Airways only triggers that 40% bonus on the largest purchase amounts. If you decide to just top up your account with 10,000 Avios, the bonus drops significantly. Buying small tranches pushes the cost per point up to a painful 1.5p or more. At 1.5p, almost every redemption becomes mathematically questionable.

If you are going to participate in this sale, you need to go big or stay home. Buying at 1.15p gives you a fighting chance to beat cash fares, provided you spend those points on the right routes.

Why short-haul Reward Flight Savers are a trap right now

Buying Avios at 1.15p to use on BA’s heavily marketed £1 short-haul flights turns a cheap European hop into a massively overpriced ticket. British Airways pushes the Reward Flight Saver hard to casual flyers because it sounds brilliant. Paying £1 in taxes feels like a win.

Look at the actual numbers. A Zone 1 European return flight, like London to Amsterdam, currently costs 18,500 Avios plus £1. If you bought those 18,500 Avios in this sale at 1.15p, your total out-of-pocket cost for the flight is £213.75. Cash fares for that exact same route on EasyJet, or even British Airways during a seat sale, are frequently under £100.

You are effectively paying double the cash price for the privilege of using points. The Avios requirements for short-haul have inflated so much over the last few years that buying points to fund European summer holidays is a terrible use of capital.

The Asia sweet spot and Club Suite economics

Redeeming bought Avios for long-haul premium cabins to Asia offers massive arbitrage, saving you thousands compared to current 2026 cash fares. This is where the 1.15p purchase price actually flexes its muscle.

Take an off-peak return flight in Club Suites from London to Tokyo Haneda. This requires 220,000 Avios plus £450 in taxes and fees. If you buy the required Avios in this sale, they will cost you £2,530. Add the £450 in taxes, and your total spend is £2,980. Cash fares for London to Tokyo in Club World currently average £5,200 or more. You are saving over £2,200 on a single ticket.

This specific route has become slightly easier to book recently. BA’s recent A380 reshuffle has resulted in higher Club Suite and First capacity on select long-haul routes. You still need to be quick, but the premium cabin award availability is marginally better than it was in early Q1.

Supercharging the deal with an Amex companion voucher

Applying a British Airways American Express Premium Plus companion voucher effectively halves the Avios required for two people, making the purchase maths virtually unbeatable. If you hold the BAPP card and have triggered your 2-for-1 voucher, this sale is your best friend.

Let’s run the Tokyo example again for a couple. Two people flying off-peak Club Suites to Haneda with a companion voucher will require 220,000 Avios plus £900 in taxes. Buying those 220,000 Avios at 1.15p costs £2,530. Your total cost for two business class returns to Japan is £3,430.

That breaks down to £1,715 per person. You cannot buy an economy cash ticket to Tokyo for much less than £1,000 right now. Flying 14 hours in a lie-flat bed for £1,715 is an absurdly good deal. If you have a companion voucher sitting in your account expiring in the next 12 months, buying the points to use it is a highly rational financial decision.

The Iberia double-dip opportunity ending 10 May

You can buy Avios in the BA sale and instantly transfer them to Iberia Plus to exploit their current 30% off redemption promotion, which runs until 10 May 2026. This is a rare convergence of two different promotions that savvy flyers should jump on immediately.

Iberia’s reward pricing is already cheaper than BA’s for specific routes, particularly to Latin America and the US East Coast. With their current 30% discount, the Avios requirements drop through the floor. You can buy the points cheaply via British Airways today, log into your account, and use the Combine My Avios tool to move them to Iberia instantly.

From there, you book ex-Madrid long-haul flights. Even factoring in the cost of a positioning flight from London to Madrid, the savings are immense. Just remember the Iberia promo expires on 10 May, so you have a very narrow window to execute this stack.

What to avoid: speculative buying and the India blackout

Never buy points without a specific redemption available today, especially with ongoing issues like the current India Avios blackout. Avios are a depreciating currency. British Airways can, and does, devalue their award charts without warning.

I regularly see people drop £3,000 in these sales because they think they might want to go to the Maldives in 2027. Do not do this. Buy points to book a flight that you have already verified is available on SeatSpy or Reward Flight Finder today.

You also need to be aware of regional IT issues. Right now, there is an active Avios blackout on routes to India. This is affecting both British Airways and Qatar Airways redemptions. If you buy points today hoping to book Qsuites to Delhi tomorrow, you will be stuck with a massive points balance you cannot use. Pivot your strategy to Southeast Asia or Japan instead.

Free alternatives to buying points

Before spending cash in this sale, look at current credit card sign-up bonuses like the Amex Business Gold which offers 60,000 points for zero first-year fee. Buying 60,000 Avios in the BA sale would cost you well over £800.

If you have a business, or operate as a sole trader, the Amex Business Gold is a much smarter way to generate a large chunk of points quickly. The Membership Rewards points transfer 1:1 to Avios. You get the points for free by hitting the minimum spend, rather than handing cash directly to British Airways.

Credit card sign-up bonuses remain the cheapest way to accumulate Avios in the UK. Sales like this 40% bonus offer should be used to top up an account for a specific, high-value redemption, not as your primary earning strategy.

Honest verdict on the May 2026 sale

The maths only works if you are booking premium long-haul cabins or using an Amex 2-for-1 voucher immediately. If you fit that profile, this is a spectacular opportunity to bypass inflated 2026 cash fares to destinations like Singapore and Tokyo.

If you just want cheap flights to Europe, or you like the idea of having a large points balance sitting there for a rainy day, keep your credit card in your wallet. The 1.15p purchase price is good, but it is not cheap enough to justify hoarding.
