It’s not every day we see round-trip fares to Europe from the West Coast for less than $400.

Thanks to Aer Lingus, the flag carrier of Ireland, you can take a trip to Dublin (DUB) towards the end of the year from just $338 round-trip.

Here are the details of the deal and the best ways to book it for yourself.

Fare Deal — Details

From Washington State to SoCal, these great value Saver fares from Aer Lingus are available from cities up and down the West Coast. The lowest is from Seattle (SEA) at $338, which, according to Google Flights, is around $196 cheaper than usual. You can expect to pay in the $400s from Los Angeles (LAX) or San Francisco (SFO).

As Aer Lingus is a full-service airline, even its lowest fares include a carry-on bag and an in-flight meal. However, you’ll need to pay extra if you want to check a bag. Another thing to note is that Aer Lingus doesn’t belong to an airline alliance, so you won’t get to enjoy any perks and benefits if you have status with American, Delta, or United.

Travel dates are from October to December 2025.

Class: Economy
Routes: Los Angeles (LAX), San Francisco (SFO), and Seattle (SEA) to Dublin (DUB)
Dates: October to December 2025
Rates: From $338 round-trip

We rarely find low fares from Seattle, so this round-trip deal for just $338 is a nice surprise.

From Los Angeles and San Francisco, the lowest fares start at $458. That’s still a great deal.

These are nonstop flights, which means you won’t connect anywhere or worry about long layovers just to get a good deal.

Best Ways To Book

The best way to find cheap flights and compare dates is heading to Google Flights. We’d recommend booking these fares directly with Aer Lingus, rather than a third-party alternative.

Using a travel rewards card, such as the Platinum Card^® from American Express, will squeeze even more value out of this booking. For example, the Amex Platinum card earns 5 Membership Rewards points per $1 spent on bookings directly with the airline or through AmexTravel.com (up to $500,000 in purchases per calendar year, then 1x). It also comes with highly-rated travel insurance and lets you visit airport lounges before departure — even when flying in economy. Enrollment for this benefit is required.

Hot Tip:

Now you’ve got your flights sorted, you’ll need somewhere to stay. If you need some help with that, too, here are our favorite boutique hotels in Dublin to give you some inspiration.

Final Thoughts

Taking that dream trip to the Emerald Isle is now more possible than ever, thanks to these excellent value fares from Aer Lingus.

If you’re feeling tempted, don’t spend too much time thinking, as fares this good aren’t likely to stick around for long.
