Although winter weather is still battering parts of Europe this week, WOW air has decided that "Spring is in the Air," allowing you to save up to 25% on travel to seven destinations in Europe.

Enter promo code WOWSPRING when booking on to apply the discount to the base fare of a round-trip purchase (It will not discount taxes and service fees). The promo code is valid for travel between April 10 - June 10, 2018.

It seems as if WOW has raised base fares on most routes before this promo code was released, so we've seen better promo code fares from them in the past. Nevertheless, you may be able to find some discounted flights for spring travel that usually don't get discounted. Keep in mind, the lowest fares will usually be found in late April and early May, there are few cheap dates available in June. Travel dates will vary by routes.

All bookings must be made by 6:59 p.m. ET, March 4, 2018, or before seats are sold out.

New York-JFK to Reykjavik $198 round-trip, nonstop

Pittsburgh to Reykjavik $205 round-trip, nonstop
