EXPIRED
British Airways amended their Boost your avios promo for a short time.
Until tomorrow, January 13th you can boost either x1, x2 or x3 all your unboosted avios you earned in 2023 for the pricing in the table below. Only avios earned, not bought or transferred, can be boosted.
As you can see, if you boost your avios x3, you will pay as low as £0,0092 or 0,011€ per avios.
This is relatively good if you have avios to boost and a redemption in mind.
Access promo here.
