Starting May 22, WOW air will begin year-round service from both Baltimore (BWI) and Boston (BOS) to Stockholm VST, connecting via Reykjavik (KEF). Special intro fares are available, starting at $149 one-way.

Fares are valid for travel on Sundays from May 22 through June 26 and again from September 4, through September 25.

Be warned that those $149 intro seats are scarce for peak summer travel. You'll have more luck finding available intro prices for travel in September.

Fares include one free carry-on weighing no more than 5kg, so pack light or pay up!

For those who prefer to check luggage, tack on an additional $67 per flight segment for bags weighing 20kg or under.
