Airfare prediction service Hopper has highlighted a major sale on Icelandair.

Seats on hundreds of flights to four popular European destinations are selling for as little as $343 round-trip, including taxes.

Fly from Boston to Copenhagen this February for as little as $343, or from Chicago to Stockholm in March for as little as $369. Flights departing from New York City’s John F. Kennedy International Airport go to Helsinki between January and March, with seats available for $383 round-trip.

And Icelandair is offering flights in December and January to Reykjavik, in Iceland, for just below $400, departing from Newark Liberty International Airport.

The latter is part of the airline’s dedicated flash sale to Iceland, which ends September 25 at midnight. Flights from Washington D.C. are $399 round-trip, and $419 from both Minneapolis as well as Chicago.

Winter is the best time to warm up in the Blue Lagoon, and this year is a great one to catch a glimpse of the Northern Lights.

Icelandair also has cheap flights to Norway, France, Germany, Belgium, and the Netherlands. All are available from various U.S. cities for less than $450. Additional flights can be found departing from Minneapolis, Orlando, Seattle, Washington, D.C., and Portland.
