A few weeks ago, Norwegian Air Shuttle announced that they would be operating flights from multiple US cities to the Caribbean (Martinique and Guadeloupe). The Open Skies agreement between the US and EU allows the carrier to fly directly from the US to the cities as they are considered French territories. The carrier will fly from JFK 3x per week and Baltimore & Boston 2x per week starting in December.
Norwegian announced the routes with $79 fares each way, though you can now find flights on some days for as low as 69 EUR or $74. Beware of the typical European low cost carrier fees though – baggage, seat selection, using a credit card, etc. Below are a few examples, in general it makes sense to select LowFare+ if you are going to be checking a bag. For 18 EUR extra you get 1 checked bag (up to 44 lbs) and the ability to select a seat. Normally, the first bag is 12 EUR and a seat reservation is another 12 EUR. In the example below, that brings the total fare up to $94…still a pretty sweet deal. If using a credit card, you’ll have to pay an additional 1.99%, about $2. Return fares are a bit more pricey but still cheaper than the major US carriers during the peak winter travel period. You can book your travel directly on their website here.
