Iberia Plus is currently offering a 20% bonus on purchases of Avios points. This deal runs until 27th January, see here for further details. Note that you need to log-in to see details of the bonus offer.
At the top end, you will be paying Euro 459 for 28,800 Avios (24,000 + 20%). That works out at 1.32p per Avios, based on £381. You would need to add a 3% foreign exchange fee to this price if your credit card has one.
This is cheaper than buying Avios via BAEC or avios.com, where you will pay £399 for 24,000 (1.66p). However, you must have been an Iberia Plus member for 90 days before you can transfer Avios across to BA.
I have been unable to move Iberia AVIOS to BA just the other way around (BA to Iberia), and I have been an Iberia member for longer than 90 days – has this become a one way street?
If you have a household BA account, it has always been like this. You can transfer Iberia -> Avios.com -> BAEC household without restrictions.
Thanks!! This is of course the case and I will definitely use Avios.com in the future…
