Washington, D.C. to Lisbon
$496$1,29762% off
Round trip
We have never seen BWI to Lisbon priced this low: $496 on Icelandair with one stop, which is both a new record for the route and 54% off the usual fare. Portugal's cobblestone streets, pastel de nata, and Atlantic coastline are hard to beat for under $500 round trip to Europe, with plenty of the calendar still open to plan around.
