Generous Avios Balance Boost promo running to Monday – buy at 0.92p
Links on Head for Points may support the site by paying a commission. See here for all partner links.
British Airways launched ‘Avios Balance Boost’ in June 2023.
It is a surprisingly good value way of buying Avios.
Put simply, you can buy a lump sum of Avios equivalent to 100%, 200% or 300% of the Avios you have earned in the last 30 days. The cost can be as low as 0.92p per Avios.
Until Monday, a flash offer makes it substantially easier to qualify to buy up to the annual 300,000 Avios cap.

What does it cost to use Avios Balance Boost?
You can find Avios Balance Boost on the usual ‘buy Avios’ page here.
Here is the standard price list:
Unless you are trying to buy over 300,000 Avios via Balance Boost, which is unlikely unless you are trying to boost a chunky credit card sign-up bonus or made a large transfer from American Express Membership Rewards, you will pay between 0.92p and 0.96p per Avios.
The 300,000 Avios cap is based on your Boost purchases over a calendar year and not per transaction.
How does Avios Balance Boost work?
Before we go into this new flash offer, let’s summarise how Avios Balance Boost works.
When you go into Avios Balance Boost you will see a list of all of your eligible transactions from the last 30 days.
You can either select individual transactions, select entire categories (eg ‘Credit Cards’) or select everything.
You will then be shown your pricing options for doing a x1, x2 or x3 boost based on the price list above.

What sort of transactions qualify for Avios Balance Boost?
You can boost:
- Avios earned from the BA shopping portal
- Avios earned from credit card spending
- Avios earned from flights
- Avios earned from ‘hotels and travel’ eg Uber
According to the terms and conditions, you CANNOT boost Avios obtained via:
“balance transfers from other airlines [presumably Qatar Airways or Finnair Avios transfers], Nectar exchanges, Avios shared or gifted by other members and previously bought Avios.”
Other inbound transfers, from American Express Membership Rewards, HSBC Premier, Heathrow Rewards etc will count for boosting.
You can only boost a transaction once.
What is the special offer?
Until Monday night (3rd February), British Airways is running a special offer.
There are two big changes:
- you can boost ALL of the Avios you earned in 2024, instead of just the last 30 days
- you can boost up to 4x the Avios you earned, instead of the usual 3x
…. with two restrictions:
- the annual cap of 300,000 Avios via Avios Balance Boost remains in place
- you can’t reboost a transaction which was previously boosted
Here’s the bottom line: for anyone who earned 75,000 Avios from qualifying transactions in 2024, you can (until Monday night) buy up to 300,000 Avios for 0.92p each.
Don’t forget that there is a 300,000 Avios cap on what can be boosted at the special rate. If you are shown a price that is higher than 0.92p per Avios then it’s because you will be over the 300,000 Avios cap.
If you earned more than 75,000 Avios last year, you need to unselect transactions until you have reduced the total to be boosted to 75,000 Avios or fewer. If you don’t, you will be paying too much.
Conclusion
If you are in the market for Avios, this is an excellent deal at 0.92p each.
Of course, however low the price, we don’t recommend buying Avios when you don’t have a specific plan to use them. The risk of devaluation is always there.
