Delta is offering a nice promotion right now for those looking to redeem their miles for a free flight from North America to Europe. With this sale, you can get up to 30% off when using points. This means an economy class ticket for a low level saver award can cost you as little as 21,000 miles one-way or 42,000 miles roundtrip. Business class seats are discounted also!
This sale is for travel between October 20, 2015 and February 29, 2016. You also must book by August 21, 2015, so you do not have much time! Since this is off-peak time for travel award availability is pretty good. Keep in mind though that Delta will tack of hefty fuel charges for one-way flights that originate in Europe. Also, make sure you sign into your Delta account prior to searching for availability to ensure the correct pricing appears.
Thanks to Delta Points for letting me know of this promotion!
