Doing anything especially fun for St. Patrick's Day this year? No? Well, here's an idea. Fly from New York to Dublin, Ireland for $503 round-trip, nonstop, incl. all taxes.
This fare is part of the current winter sale from Aer Lingus, valid for travel on Monday through Thursday, from January 11 through March 31. You'll also find other destinations on offer, including Amsterdam, Barcelona, Birmingham, Brussels, Paris, Malaga, Krakow, Warsaw, and others. Depart from New York, Boston, Chicago, or Orlando.
For weekend travel, be sure to tack on an additional $15 to each leg of your trip.
