Lucky’s One Mile at a Time blog on BoardingArea.com commented on this bargain award redemption. British Airways has gained a reputation for high fuel surcharges on award flights that mean a “free” flight is far from free. So one of the best uses of Avios is to redeem for transatlantic travel on Aer Lingus with minimal fuel surcharges. And because the British Airways Executive Club award chart is distance based, you can for example, fly from Boston to London for 20,000 Avios one-way and then from London to Dublin for 4,500 miles one-way in coach. So the total cost for a roundtrip coach ticket would be 49,000 Avios. The total cost for a roundtrip in business class would be 98,000 Avios. Lucky also has a rather lengthy study of using Avios on Iberia at http://insideflyerus.wpengine.com/link/?6753
