Aer Lingus fares to Ireland for less than $500 one-way

Aer Lingus wants to get your summer travel plans in order with an enticing new sale. Ireland's national airline is currently offering summer travel discounts to the Emerald Isle.

You can score up to $100 off round-trip flights from a number of U.S. cities that Aer Lingus operates from. The sale applies to flights between April 15 and Sept. 30 of this year. That's a nice wide window of availability that is larger than you typically see in these flash sales.

This sale is for base economy fares, and most (though not all, as you'll see below) have layovers. With Aer Lingus, economy-tier tickets get you a free carry-on bag. If you want to check luggage, it will cost you around $55 each way. If you travel light, you can really take advantage of this deal.

I live in Miami, so I'll start with a nice deal I found on a flight to the Irish capital. This round-trip itinerary from Miami International Airport (MIA) to Dublin Airport (DUB) in late April costs less than $1,000 with the applied $100 discount. There is a layover in Chicago, but if saving a significant amount of money is worth the longer travel time, this is a good option.

Aer Lingus resumes service out of Minneapolis on April 29, and you can find some great availability for travel to Ireland from the Twin Cities. We found lots of availability in this sale, including this nonstop trip from Minneapolis-St. Paul International Airport (MSP) to Dublin in mid-May for $776.27 round-trip with the applied discount.

The airline is also debuting service out of Denver on May 17, so Rocky Mountain travelers can enjoy the savings as well.

Here are a couple of summer itineraries to Dublin we found out of Denver International Airport (DEN) in the summer, with nonstop return flights. According to Google Flights, these prices are almost $400 less than normal.

If you want to travel in August, you can get this same route for less than $900 round-trip. Making this even more appealing, you would fly nonstop each way.

Chicago is another city with lots of availability in this deal.

August was wide-open, with many round-trip fares to Ireland for less than $800. Here's one nonstop itinerary in early August from O'Hare International Airport (ORD) to Dublin for just $779 with the discount. This flight usually costs more than $1,000, so you're saving a large amount.
