Aer Lingus Fare Deal — Details 

Aer Lingus, Ireland’s flag carrier, is running a January flash sale on many U.S. routes, with round-trip flights under $500. The deal covers flights to Dublin (DUB), as well as European destinations served by the airline, such as Paris (CDG) and Rome (FCO).

Most U.S. cities served by Aer Lingus are included in the deal, including Boston (BOS), Chicago (ORD), Las Vegas (LAS), Los Angeles (LAX), New York (JFK), Newark (EWR), San Francisco (SFO), and Seattle (SEA).

If any of these deals catch your eye, make sure book directly with Aer Lingus for the best deals.

Hot Tip:

The cheapest sale tickets are also the most restrictive, as you’re allotted just 1 carry-on bag and a complimentary meal. For more flexibility, make sure to book a “Smart” or “Flex” fare.

Best Ways To Book

There’s wide open availablility between now and mid-May, so you shouldn’t have trouble finding dates or destinations that work for you.

There are several terms and conditions to keep in mind before booking. These fares are nonrefundable and available only in economy class. Additionally, there may be blackout dates during holidays or other peak travel days.

A Saturday night minimum stay is required, and a 7-day advance purchase is required for flights to Great Britain and continental Europe. This offer is valid for new bookings only. Finally, you must book by January 22 to snag the deal.

Make sure to book your flight using a card that rewards you for travel purchases, such as the Platinum Card® from American Express, Chase Sapphire Reserve®, or the Capital One Venture X Rewards Credit Card.

You can also book with an Avios-earning credit card, such as the British Airways Visa Signature® Card or Aer Lingus Visa Signature® Card — both of which earn 3 Avios per $1 spent on Aer Lingus flights.
