Delta is advertising a fare sale for travel from August 6 to December 16, and, in a first, is advertising a concurrent sale on the award prices on the same routes.

There are 29 listed sale routes.

When 5,000 mile awards started in May, I wrote that this was mixed news:

Good: Some awards are 60% cheaper, and hopefully more routes with 5,000 mile award space are added.
Bad: By picking 5k routes on cheapness not distance, Delta is taking a step away from award charts (which it deleted from the internet already) and toward revenue-based redemptions.
