Aer Lingus has some sweet spots as well, like the US to Ireland for 13,000 – 16,250 Avios with no surcharges or 50,000 Avios – 62,500 Avios each way in Business Class. This would be if you find space on Aer Lingus metal. The lower pricing is from the East Coast, the higher is West Coast.
Combinable with other Avios programs like BA.
