Cheap Flights to Europe: Real Prices From US Airports in 2026

London from $349 round-trip on Norse Atlantic out of JFK is the number that usually stops people mid-scroll. Most Americans have written off Europe as a $900 flight minimum, and that assumption is just wrong.

Reykjavik from $329 round-trip on Icelandair is actually the cheapest transatlantic fare you'll consistently find right now, and Icelandair flies from JFK, Boston Logan, Seattle-Tacoma and a handful of other US gateways. That's a sub-$330 round-trip to Europe, full stop.

Lisbon from $389 round-trip on TAP Air Portugal out of Newark is the sleeper deal on this list. TAP runs a solid transatlantic product and Newark gives you less competition for cabs than JFK, which is a small but real win.

Dublin from $399 round-trip on Aer Lingus out of JFK is worth flagging because Aer Lingus includes US preclearance at Dublin Airport, meaning you clear US customs before you land back home. Rome from $449 round-trip on ITA Airways out of JFK rounds out the list, and for a direct shot to Italy, that price is genuinely hard to argue with.

Flying into Lisbon, Dublin or Reykjavik instead of London or Paris typically saves you $100 to $250 on the transatlantic leg alone. London Heathrow on British Airways from JFK runs $550 to $700 round-trip most of the year. That same travel window into Lisbon on TAP from Newark is $389. The math is obvious.

Dublin is the cleaner version of this strategy for anyone wanting to do a multi-country trip. Aer Lingus from JFK to Dublin from $399 round-trip, and from Dublin you can get to London, Paris or Amsterdam on Ryanair or Aer Lingus for $30 to $80 one-way. You've just built a two-city Europe trip for less than a direct New York to London fare on a legacy carrier.

Reykjavik pulls double duty. Icelandair from Boston Logan to Reykjavik from $329 round-trip gives you Iceland itself, which is a full trip on its own, plus Icelandair's stopover program lets you add a free layover in Reykjavik on the way to or from other European cities. Paris, Copenhagen, Amsterdam, all bookable as add-ons from the same ticket.

The Lisbon gateway is underrated for Southern Europe access. TAP connects onward to Madrid, Barcelona, Porto and the Algarve at prices that make the math work out well. Flying Newark to Lisbon on TAP from $389 then grabbing a $40 TAP regional connection to Porto beats any direct New York to Barcelona fare you'll find on American Airlines or Iberia most of the year.

Norse Atlantic and Icelandair are the two names you'll keep seeing on cheap transatlantic searches, and they are not the same thing. Norse Atlantic from JFK to London Gatwick from $349 round-trip is a true ultra-low-cost carrier. The base fare includes your seat and a personal item that fits under the seat in front of you. That's it. A carry-on bag adds $50 to $70 each way, a checked bag runs $60 to $90 each way, and seat selection costs extra on top of that.

Run the numbers before you book Norse. If you're traveling with one carry-on each way, you're adding $100 to $140 to that $349 base. You're still often at $489 to $489 round-trip to London, which beats most legacy carrier fares, but the sticker price is not the real price. Two checked bags round-trip and you've closed the gap significantly.

Icelandair sits in a slightly different lane. Icelandair from JFK to Reykjavik from $329 round-trip includes a carry-on in most fare classes, which already puts it ahead of Norse on value for light packers. The onboard product is decent, the legroom is average, and the flights run reliably. For a carry-on-only traveler, Icelandair is close to a legacy carrier experience at a budget price.

When to pay more: if you're flying peak summer, checking two bags, or traveling with kids who need seat assignments, the gap between budget carriers and Delta or United narrows fast. Delta from JFK to London Heathrow from $620 round-trip in summer includes bags, better seat options and a more reliable connection if something goes wrong. For January travel with a carry-on, Norse at $349 is the obvious call.

January and February are the cheapest months to fly transatlantic, by a significant margin. The same Norse Atlantic JFK to London route that runs $349 in February will be $550 to $700 in July. On legacy carriers the spread is even wider. Delta and United transatlantic fares in peak summer regularly run $200 to $400 more than the same routes in January. The flights are the same planes, the same routes. The difference is pure demand.

The booking window matters more than most people realize. For summer departures, book 3 to 4 months out. That means November and December for June and July travel. For off-peak travel, January through March, 6 to 8 weeks out is the sweet spot. Airlines drop prices to fill seats in the slow season, and waiting a bit actually works in your favor.

JFK is the single best US airport for transatlantic competition. More airlines fly transatlantic from JFK than anywhere else in the country, which means more fare wars and more options across every budget level. Newark is a close second and often cheaper on TAP and United routes. Boston Logan is strong for Icelandair and Aer Lingus, with Aer Lingus from Boston to Dublin regularly coming in around $389 to $429 round-trip.

Miami, Atlanta and Chicago O'Hare all have solid transatlantic options, mostly through legacy carriers. American Airlines from Miami to London Heathrow from $549 round-trip and Delta from Atlanta to Paris Charles de Gaulle from $520 round-trip in the off-season are the standout routes from those cities. LAX has the fewest transatlantic options of the group, and fares from Los Angeles to Europe tend to run $50 to $150 higher than equivalent East Coast departures. If you're based in LA and the price gap is significant, a cheap domestic connector to JFK or Newark can genuinely save money on the total trip.
