Thanks to Aer Lingus and Delta, you can experience the magic and myths of Ireland from just $319.

These round-trip fares to Dublin (DUB) are around a third cheaper than you’d normally pay, and we consider that a great deal worth telling you about.

Let’s take a look at the details.

Fare Deal — Details

Fares like this to Europe are usually associated with low-cost airlines like Norse or LEVEL, but not on this occasion.

For a fraction of the usual cost, you can fly nonstop from Boston (BOS) with Aer Lingus or New York (JFK) with Delta throughout fall and winter.

Even if Dublin wasn’t at the top of your “to visit” list, you could leverage the city’s status as the home base of Ryanair — Europe’s largest low-cost airline — to check out another European city. The European Christmas markets come highly recommended!

Class: Economy
Routes: Boston (BOS) and New York (JFK) to Dublin (DUB)
Dates: November 2025 through March 2026
Fares: As low as $319 round-trip

The lowest fares are with Delta and can be found throughout fall and winter. At $319, you won’t be surprised to learn these are Delta’s basic economy fares, so checked bags aren’t included (unless you have Delta Medallion status or a Delta credit card). The price increases by almost double for a Main Cabin economy fare.

Aer Lingus’s fares from Boston start at $20 more than Delta’s from New York. Similarly, these fares don’t include a checked bag.

Best Ways To Book

You can easily find these fares by doing a quick search on Google Flights‘ handy Explore tool.

The fares are available on multiple departure dates from October to March, so there should be an option that works for your schedule.

When paying cash for flights over using points, we always advise using a credit card that rewards you for travel purchases if you can.

A great card to consider using when booking these flights is the Platinum Card^® from American Express, offering 5 points per $1 spent on flights purchased directly with an airline with AmexTravel.com (up to $500,000 of these purchases per year, then 1x earnings). If you’re a frequent Delta flyer, you might even consider one of the airline’s cobranded credit cards for specific Delta-related perks and benefits.

Final Thoughts

Booking a trip to Ireland with Aer Lingus and Delta could be just what you need to take your mind of the fact that summer is slowly fading away.

As the headquarters and main hub for European low-cost giant Ryanair, Dublin is also a great jumping-off point for exploring other destinations in Europe.
