British Airways Avios: 40% Bonus on Purchased Miles — Ends April 27

Bought Avios get a bad rap — and usually, that's fair. But when you're a few thousand short of a sweet redemption and the alternative is waiting months for another transfer or earning opportunity, a purchase bonus can absolutely close the gap. A 40% bonus meaningfully improves the per-mile cost, which changes the math on whether buying makes sense for your specific redemption. The offer runs through April 27, 2026, so you've got a tight window. Before you buy, lock in the award availability you're targeting first — there's no point in topping up a balance for a seat that's already gone. If the space is there and the numbers work for your redemption, this is a reasonable move. Bought Avios do count toward your balance the same as earned miles, so any redemption you'd normally make is on the table. Just make sure you've done the per-mile math against what you'd pay in cash for the same ticket — buying points only wins when the redemption value clears that bar.
