WOW Air has a generous 50% off sale going on that can get you some great prices on flights to Europe during the first months of 2017. To take advantage of the offer you need to book today by 7:59pm ET for travel between January 14 and April 5, 2017. Use promo code WOWXMAS16 in your search.

The discount is on the base fare, which makes up about half of the price. You need to pay full taxes and fees. It should still work out to a nice discount in the 25-30% range. And they decent prices to start with.

WOW Air only flies out a few US cities so this won’t be for everyone. The best prices will be for travel to Rejkjavik, but WOW Air also has other destinations in Europe.

For Rejkjavik flights, you can get a round-trip direct flight from NYC for just $211. It gets even cheaper if you’re in Baltimore or Boston, just $191. The same $211 price is also available from LA and San Francisco.

If you’re interested, make sure you book as soon as possbile. Also don’t forget to use a credit card that will give you the most points, such as Amex Platinum (5x on airfare) or Chase Sapphire Reserve (3x on travel) or Citi Prestige (3x on airfare).
