For those of you who are interested in traveling to Barcelona between November and March, Norwegian Airlines has plenty of dates for airfare as low as $313 round trip from Boston and $344 round trip from Newark. Norwegian does charge to check in luggage and they do not serve complimentary meals on international flights so that is something to keep in mind. But even with the added cost, it is still a great deal to one my favorite cities in Europe and one that routinely lands on TripAdvisor’s top 25 cities in the world. Norwegian has a relatively young fleet and utilizes the Boeing 787 Dreamliner on these routes. I flew on this plane on the Norwegian metal two years ago and had a pretty comfortable experience in economy. If you conduct a search on Google flights, you will get a calendar that shows you the low fares on various dates. Below is a sample itinerary from Newark (EWR) from January 21st to January 29th.
