Check out these super cheap fares from Level for travel from Boston to Barcelona in Spain. One way fares going to Europe are just $92. And that’s for non-stop flights. But even roundtrip fares can be booked from $199. Dates are limited, but you can find them in January and February. Not the best time to visit but winters there will usually not be extremely cold. Plus you can avoid the crowds and get to see more of the city.
Looks like you can get better prices if you book each leg separately.
Definitely great prices, but very limited dates. Don’t forget to use Amex Platinum (5x on airfare), Citi Prestige (5x on airfare), Chase Sapphire Reserve (3x on travel) or any of the best credit cards for travel purchases.
Let me know if you find other dates with the same price, or any other routes.
