Norwegian has really introduced cheap fares to a number of US transatlantic routes. And oddly it’s worth searching their website in different currencies — because you get different prices. There are arbitrage opportunities in this case from the same seller.

Instead of booking at Norwegian.com – where TheFlightDeal is seeing those cheap fares — if you book on Norwegian’s website you’ll find even lower prices.

You can use Google translate but the booking engine is intuitive even without it. The best thing to do is choose Norwegian’s “Low Fare Calendar” showing dates with the cheapest flights.
