While all the sub $300 flights from New York are getting all the hype and rightfully so. There are still some good deals to London and Warsaw from other U.S. cities that are also available during this epic Iberia sale. This is about $200 off the regular price for this route, it may not be as cheap as Brussels or Milan, but it's still a great deal. Speaking of deals, why not get a free Warsaw city guide for your iPhone/iPad from Lonely Planet while you are at it to plan your trip.
