Buy Iberia Avios With Groupon, Can Convert to British Air Avios

BA Avios are handy because reservations made with them (including for American Airlines flights) can be cancelled for only about $3. This compares very, very favorably with the $150 cost to cancel a reservation for the same flight made with AAdvantage miles.

You can purchase up to 100,000 Iberia Avios with a current Groupon deal, then convert them to BA Avios.

Groupon Selling Iberia Plus Avios (Again)

As an added consideration, you can purchase as few as 2000 IB Avios which is likely to protect any existing points from expiring.
