$533 - Direct Flights to Madrid from Boston

Air Canada is offering direct flights to Madrid from Boston for $533 including all taxes and fees.

Flights are the cheapest early in the week, but flights on the weekends are under $700 on most weekends as well.

US Airways is also offering one-stop flights roundtrip for about $10 more than Air Canada, with layovers in Philadelphia, and which take about twice as long.

Direct flights are about 7 hours long.

So, if you can, fly Monday-Wednesday. You’ll save at least $100 dollars, cut out at least 14 hours of extra travel time, and reduce the chances of missing a stopover or getting delayed at some of the busiest airports in the world.
