You’d expect flights to Ireland to be on sale during the winter months, when rain on the Emerald Isle is pretty much a guarantee, but it might be a little more surprising that Aer Lingus has flights to Ireland on sale for the spring and summer, too (when rain is only highly likely). But if you can book a trip by January 21 – this Wednesday – you can score some great airfare deals.

In the spring (April 1-June 15), for instance, you can fly from New York or Boston to Ireland for as little as $398 round-trip. Summer travel (June 16-August 31) is only slightly more expensive, with that same flight being available starting at just $498 round-trip.

And Aer Lingus also offers vacation packages in Ireland, too. The “Emerald Package” includes round-trip airfare, 1 night in a hotel, 5 nights in a B&B, and a rental car for a week. The spring price starts at just $699 per person, and in the summer you can go for as little as $799 per person.

There are other departure cities available for the flight deals, and other vacation packages available as well – so if you’ve got a trip to Ireland on the docket for this spring or summer, be sure to check out Aer Lingus’ deals on their website – and book by Wednesday to get the best prices.
