The airline Norwegian Air Shuttle ASA just announced its plan to sell $69 one-way tickets to Europe from select U.S. airports. The initiative is slated to roll out by as soon as 2017 (although for would-be international travelers, “soon” might be a relative term).

Flying to Europe On a Budget: Here’s the Scoop

While the lure of cheap international tickets may have travel-lovers drooling, travelers looking to take advantage of the deals will be limited to only a few destinations—namely, Edinburgh, Scotland, and Bergen, Norway.

The airline believes it can reduce fares by flying out of U.S. airports that currently offer limited international service (or none at all), reports NBC News. That’s because those airports will charge airlines lower operating fees, meaning both airlines and travelers won’t incur the same costs that they would at more heavily trafficked international airports. Currently, Norwegian Air has its eye on New York’s Westchester County Airport and Connecticut’s Bradley International Airport.

Thanks to this low-cost strategy, Europe’s third-largest budget airline anticipates charging an average of $300 round trip for the nonstop routes named above—that’s several hundred dollars cheaper than the average cost of flights leaving from the United States’ busier international airports.

Still, travelers looking to take advantage of these deals will want to remember that the flights will come with added fees for everything from checking luggage to booking a seat assignment or ordering an in-flight meal (even for overnight trips),reports Condé Nast Traveler. Savvy travelers can subvert some of these budget-friendly airline tactics by packing everything in their carry-on and bringing along their own snacks for the flight.

In charging lower fares, Norwegian Air hopes to draw customers away from more well-known international carriers. The airline has already ordered 100 new Boeing jets and plans to receive the first five in 2017, at which point it expects to begin rolling out the cheaper flights. Of course, the airline’s ability to do so will hinge on the smaller U.S. airports’ willingness to set up customs stations that are equipped to process international travelers.

The Beginning of a Trend?

Norwegian Air isn’t the only airline to start toying with lower cross-Atlantic fares. Iceland’s Wow Air reportedly has started offering $99 one-way fares from Boston to Paris, while Eurowings (a subsidiary of Lufthansa) has also begun offering some cheaper international flights. And while Norwegian Air awaits its arsenal of low-cost jets, the airline is offering $300 nonstop, round-trip tickets from New York to Oslo, Norway from December 2015 through February 2016.
