Shannon, Ireland in $430s-$580s RT

So, yesterday's massive TAP sale dropped some prices to Dublin, but if you're aiming for Shannon, you can skip the extra commute by flying with American and Aer Lingus.

What's in Shannon, you ask?

Well, no trip to Ireland is complete without a castle visit, and near Shannon, there's Bunratty Castle, where you can explore a 15th-century tower house and its folk park. If you time it right, you could even attend a Medieval Banquet dinner.

And let's not forget hiking up any of the six national parks – they're dramatic in the winter and way less crowded. 

After all that adventure, you'd want to spend a day at the Kilkee Thalassotherapy Centre, where you can enjoy warm seaweed baths - bliss!

P.S. If you're flying from New York, you can opt for non-stop flights for a little extra.
