For a limited time, Scandinavian Airlines is offering U.S. travelers a kids fly for free promotion, offering free round-trip base airfare for any children traveling with an adult from August 20, 2018 through March 30, 2019. (You’ll still have to pay taxes and fees for each passenger.)
Flights are available from SAS' seven U.S. gateways in Boston, New York, Miami, Chicago, San Francisco, Los Angeles, and Washington, D.C.
Flights must be booked directly through the airline's website by May 13, and to qualify kids must be 11 or under. Check the airline’s Low Price Calendar to see when you can get the lowest fares.
