With these deals, you don't have to be Irish to be lucky. In honor of St. Patrick's Day, Ireland is on sale from Norwegian Air. While this isn't the most encompassing sale it does offer some great nonstop prices for those departing from Providence PVD and New York-Stewart SWF airports.
Seats are available from mid-April through mid-June then again from late August through October. Travel days vary by route. The prices book into what Norwegian calls "LowFare" which only includes 10Kg of hand luggage (one carry-on up to 55x40x23 cm & one personal item that can fit underneath your seat). Checked baggage requires an additional charge.
Tickets must be before midnight on March 19, 2018.

Providence to Dublin $244 round-trip
Providence to Shannon $234 round-trip
Providence to Belfast $273 round-trip
