Use that on Scandinavian Airlines to get from US->Oslo->KEF in Iceland.
airberlin and Niki fly there seasonally, so that is an AA/oneworld option. WOW airlines, Easyjet and several other non aligned or LCCs connect KEF with UK and Europe, so you may be able to use miles to one of their destinations and then buy a relatively cheap ticket to KEF...just an option possibly
