How much did you budget for your flights to Europe this year? $1,000? $700? What if I told you to halve that … or less?

It might sound crazy, but in a world where seemingly everything costs more, flights to Europe could cost you way, way less in 2025 … but only if you book right now. 

 

BOS to Madrid airfare

 

Spring break in Madrid (MAD) for $347 roundtrip is a mind-blowing flight price. Same for these October flights to Dublin (DUB) from Seattle (SEA), too. 

 

Seattle to Dublin roundtrip airfare in the $300s.

 

This latest sale really knocked our socks off. It included Aer Lingus, American, and Iberia (all OneWorld alliance partners) offering roundtrip fares in the $300s from several U.S. cities from coast-to-coast. And it followed in the footsteps of a handful of other deals offering crazy cheap fares this year and next. 

Here's the gist: If you want to save big money on your 2025 or 2026 Europe trip, it's time to book right now. That's what our Thrifty Traveler Premium subscribers have been doing over the past few days, thanks to these sizzling flight deals. 

Check out just how cheap it can get.

 

 

Madrid, Dublin, & More Under $398 RT (The Deal of the Year?)

When airfare nosedives into the $300s roundtrip from multiple U.S. gateways, we're always quick to find it. That's exactly what happened Thursday night, which is why Thrifty Traveler Premium members got this email alert just a few minutes later. 

 

Europe flight deal under $396 roundtrip.

 

Delta hubs from coast-to-coast all benefitted from these beautiful roundtrip fares to Europe. The flights themselves are on American and its foreign partners (Finnair, Iberia, Aer Lingus, and more), so it's clear American is targeting some Delta flyers with these promotional fares. But the reason doesn't matter, the end result is one of the cheapest flights to Europe you'l ever book. 

 

Europe fares in the $300s roundtrip.

 

While many of the best fares can be found in fall and winter of this year, many cities included peak summer fares like this one from Minneapolis (MSP) to Dublin (DUB). 

 

Minneapolis to Dublin airfare for $355 roundtrip.

 

 

Other peak times include these spring break fares from Detroit (DTW) to Madrid (MAD), too. 

 

Detroit to Madrid for $367 roundtrip.

 

And Salt Lake City (SLC), a place where cheap Europe flights can be hard to come by, also jumped into this deal with fares like these up to Helsinki (HEL) to see the Northern Lights this fall. 

 

Salt lake City to Helsinki fare for $361 roundtrip.

 

I won't soon forget this flight deal, and neither will the Premium members who just halved their vacation budget (or were able to up their budget on lodging, food, and drinks instead!) and are taking the trip of a lifetime this year. 

 

Iceland and Europe in the $300s RT

Iceland fares are often cheaper than the rest of Europe because the flight is much shorter and therefore cheaper to operate. And with Icelandair crushing the competition with insanely cheap flights to Reykjavik (KEF), travelers like you and me are the winners. 

 

Icelandair fare from JFK to Reykjavik for $316 roundtrip.

 

This latest Icelandair sale included several flights to Europe in the $300s roundtrip, including many nonstops to Reykjavik and one-stop itineraries to Dublin (DUB) and Stockholm (ARN).

The beauty of these fares? They're eligible for free Iceland stopovers. Read our guide to booking a stopover to see two countries for the price of one. 

 

Scandinavia and Europe in the $300s RT

These Nordic carriers love cheap flights almost as much as we do, it seems. Scandinavian Airlines, like Icelandair, is known for its incredible sales. 

 

BOS to BRU SAS fares

 

With one quick stop in Copenhagen (CPH), you can fly all over Northern, Western, and Eastern Europe in the $400s easily, and in some cases, in the $300s, too!

Brussels (BRU) seems to benefit most starkly from these low fares, but if you're flying from Boston (BOS), for instance, you can fly roundtrip to far-flung destinations like Bergen (BGO), Stavanger (SVG), and Milan (MXP) for less than $399 roundtrip. 

 

Nonstop on Norse Atlantic in the $300s RT

The airlines we outlined above were what we call “full-service” airlines. That essentially means you can expect perks like a carry-on bag, free refreshments on board, and even a meal in most cases. But some airlines, like ultra-low-cost Norse Atlantic doesn't always include those perks. 

But because they offer such competitive rates, we still search for those fares – making sure to factor in the cost of a carry-on bag. 

 

Norse Atlantic fares in the $300s

 

The results: Some insanely cheap fares – even with a carry-on bag. I flew Norse Atlantic and found it to be just fine. Nothing more, nothing less. Just fine. But for $363 roundtrip for a nonstop flight to Rome (FCO), “fine” is all I need!

Norse's funky point-to-point routes connect New York, Florida, and L.A. with some of the most coveted travel destinations in Europe. You should at least consider flying the carrier to save the most on your next flight across the pond. 

 

Bottom Line

Flights to Europe don't have to be expensive. In fact, they don't have to cost more than a trip to Florida this year!

You'd be surprised how inexpensive it might be to fly to Europe this year or next, with several routes coming in under $399 roundtrip. The key? You'll need to book soon while these fares are still at their lowest.
