Just logged in to my account and my balance has increased by about 30,000 points. Looking at the account statement there are 3 manual credits for today - 2 for 15k each and 1 for 333 points. I usually redeem for Iberia Avios or Hilton. Both have restrictions that only allow redemptions every 1 or 2 months, so I can't easily empty the account and ditch it if they try to correct what must be a mistake. Unless I've won some prize draw - do they even run prize draws?
