I'm not sure if this is targeted but for those interested.

Inflate your Avios balance with up to 100,000 Avios (140k = £1615)

There's never been a better time to treat yourself – or someone else. For a limited time between 00:01 hr GMT Tuesday 24 May 2016 and 23:59 hr GMT Thursday 26 May 2016, you'll be able to purchase up to 100,000 Avios and get a 40% bonus, in our three day flash sale.

ETA:

Iberia are also offering the same but at 1800 Euros so that's £1391. To purchase them there you have to have had an account for at least 90 days. You can then transfer them over to BA via Avios.com (If I recall corectly that's how you do it?)
