Aer Lingus wants you to unwind in the Emerald Isle after all the holiday hubbub has come and gone. The Irish flag carrier is offering a Black Flyday deal that shaves $50 off roundtrip flights departing its East Coast network and $100 off itineraries leaving its West Coast airports to Ireland. No promo code needed!

The discounts apply to all flights, but we’ve weaved through Aer Lingus's booking calendar to find the cheapest flight options below. Discounts are valid for flights departing from January 8 through March 22, 2019, which overlaps with the St. Patricks Day festivities for those looking for reduced rates to raise a pint of Guinness in the streets of Dublin.
