Try checking flights from Baltimore to Amsterdam....it's usually less expensive than the other 2 airports. I found a Baltimore fare on Icelandair, June 12-19, change of planes in Iceland, for $891, through Travelocity.

If you really plan to travel, I'd get your ticket as soon as possible. Usually the summer sales are over by now. Occasionally, there will be something for later in the summer, but not at the beginning.
