Hi Bert!If you are flexible and you really want to visit Iceland, you can do it for very little money.
Scenario #1 - Fly from BWI or JFK to London (where you might be going anyway) and there is no additional airfare charge for a stopover of 1, 2 or 3 days.
Scenario #2 - You can fly to Iceland for a couple of days in Winter with a bare bones land package for $300 - $350. Tax is additional.
All the best,
Dan
