Fares to Iceland keep getting cheaper. Icelandair has an unadvertised $89 each way fare from New York or Boston to Reykjavik through March. Please go. I may even beg my rather pregnant wife about taking advantage of this one. Or not. But if your wife isn’t about to have twins, you really should visit—I’ve never seen fares this low.
In any case, you have to sign up for Lucky Fares to see the fares (they don’t show up in the regular fare listings).
