Avios Balance Booster offer ending and a useful trick

British Airways launched a new feature called Balance Booster in June that introduced a new way of purchasing Avios at a lower cost. There is an ongoing 10% bonus that will end on Monday, so don’t miss out if you need to top up your account.

The annoying part is that you can only purchase maximum triple the amount that you’ve earned in the last 30 days, which may not be enough. Interestingly, a reader has shared a trick / loophole that allows you to work around that cap and buy more.

When you land on the Balance Booster page, the frontend will only load past transactions that haven’t been boosted. When you complete a purchase, the backend will update the record to mark that transaction as “boosted”.

However, there’s a delay before the frontend is notified of that change. It means that you have a short time window to boost the transaction again (and more) if you are quick enough.

I tried it once and it worked out. The delay was approximately five minutes.

Beware that it is a loophole so there’s some risk associated, although I think it’s fairly low. At the end of day you are paying money to BA, and there’s the 250,000 Avios cap which prevents unlimited boosting, so it should be fine.
