Nationwide Delta SkyMiles Sale: Mexico Beaches from 12K Round-Trip
Washington, D.C. (DCA) to Cancún (CUN), Economy, Round Trip.
Delta ran a flash sale on four Mexican beach destinations — Cancún, Los Cabos, Puerto Vallarta and Tulum — with round-trip Economy awards from 12,000 SkyMiles plus about $148 in taxes. Washington, D.C. to Cancún was one of dozens of 12K city pairs; the same trip in cash runs around $368 round-trip, which works out to roughly 1.84 cents per mile. Best availability was August through September, with a handful of nonstops out of Atlanta, Minneapolis and Los Angeles.
