Flash sale: Round-trip fares to Ireland for less than $400

Earlier this year, Aer Lingus announced that it would begin offering nonstop service between Dublin Airport (DUB) and Harry Reid International Airport (LAS) in Las Vegas on Oct. 25. The new route will be a seasonal offering, with the Dublin-based carrier flying to Vegas on a wide-body Airbus A330-300 three times weekly (Tuesday, Thursday and Saturday).

The new route marks the airline’s 18th route to the U.S. from Dublin. It also marks the first time an airline has taken over the Sphere; the airline timed its Sphere appearance to coincide with the inaugural flight’s arrival into LAS.

To celebrate Friday’s inaugural flight to Sin City, Ireland’s flagship carrier is making everyone a winner with a flash sale on all round-trip flights between the U.S. and Ireland. Flights go to DUB or Shannon Airport (SNN) in Shannon, Ireland.

Aer Lingus is offering round-trip economy fares for just $399 during the sale dates. (This sale is only valid for round-trip economy fares.)

Act fast if you want to hit this jackpot, as the booking window ends Oct. 26.
