While some have criticized the Delta SkyMiles program for its less-than-great mileage options, they do offer some inexpensive domestic award flights that make using this program worthwhile. On top of that, Delta is a member of SkyTeam Alliance, meaning you can redeem your SkyMiles with any SkyTeam Alliance member. These airlines include:

Unfortunately, Delta was one of the first airlines to get rid of its public award chart and change to a dynamic pricing system for award flights.

Through March 15, 2017 (this Wednesday) at 11:59 PM ET, you can book roundtrips to Europe in Delta One for travel August through October for only 110,000 Delta miles. The standard price is 140,000 miles roundtrip.

This isn't a particularly earth shattering award price to Europe in a flat bed. You can fly United or American's Business Class for almost the same price any time you can find award space (price is 57,500 United miles or 57,500 American miles respectively).
