We’re seeing round-trip fares from several US cities (including the West Coast) to Oslo (OSL), Stockholm (ARN), Copenhagen (CPH) and Helsinki (HEL) from just $339, valid for departures January through May 2017. The best deals seem to be on Icelandair, but other carriers like Air Canada, Norwegian and United are also offering discounts from certain cities. Search for your desired destination and dates on Google Flights, then continue booking through the airline’s website (if possible) or with OTA like Orbitz.Airline: Icelandair and moreRoute: US cities to OSL, ARN, CPH and HELCost: $339+ round-trip in economyDates: January – May 2017Booking Link: Orbitz Pay With: Amex Platinum, Chase Sapphire Reserve, American Express Premier Rewards Gold, Citi Prestige or Chase Sapphire PreferredHere’s an example of what you can book:Boston (BOS) to Oslo (OSL) for $339 round-trip on Icelandair in January:Boston (BOS) to Oslo (OSL) for $339 round-trip.New York (JFK) to Stockholm (ARN) for $344 round-trip on Icelandair in January:New York (JFK) to Stockholm (ARN) for $344 round-trip.New York (JFK) to Copenhagen (CPH) for $346 round-trip on Icelandair in January:New York (JFK) to Copenhagen (CPH) for $346 round-trip.Seattle (SEA) to Helsinki (HEL) for $434 round-trip on Icelandair in January:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
