Best deal here is going to be on KLM. It’ll set you back about $539, and you’ll be heading to Dublin. You’ll depart from JFK and have a quick plane switch-a-roo in Amsterdam. If your dates are a little flexible. Here, even doing the unpopular Tuesday-to-Tuesday trip, isn't going to save much.
The Windy City is a little pricey, so you might want to just stick around and enjoy the green river from the comfort of your hometown. Best deal here is found on Orbitz, but it’s on US Airways going to Dublin and Aer Lingus coming back. Two-stops on the way back to the US makes it messy, so we say pass on the $750 fare.
If you want to escape from Hotlanta, you’ll be using Air France to head overseas. It will cost you about $850, and you’ll obviously be connecting in Paris. Moving the dates around a little doesn’t seem to help things at all.
Our deal fare is out of the nation’s capital. For those with flexible travel plans, you can head out from Dulles on Mar 15 and return on Mar 24. You’ll be flying on Delta with connections in ATL on the departure and JFK on the return for only $454. Not too bad, especially if paired with a cool a hotel thanks to Hotelchatter.
