Cranky Flier points out the absurdity of Delta’s one-way awards. Delta doesn’t offer one-way awards for less than the roundtrip price, they just price the award as a roundtrip at double the mileage cost of the segment you choose.
So if only ‘medium’ awards are available for a simple domestic one-way flight, that’s 20,000 miles one-way so 40,000 miles roundtrip. And the one-way domestic segment is 40,000 miles.
Note that if only high is available, then the one-way would be 60,000 miles. Now, a one-way award with last seat availability in domestic coach on United or American would be 25,000 miles. See the difference?
But as Cranky points out, if you needed last seat availability on Delta (60,000 miles for a one-way) you’d just book last seat availability outbound, and pick a random return flight that was available at the ‘low’ (i.e. “standard” or “normal”) level and it would price as 30,000 (outbound) + 12,500 (return) = 42,500.. for a savings of 17,500 miles. Still more than American or United (duh) but much less expensive.
Now that United and American offer one-way awards, one would think that Delta would need to offer them (at half the roundtrip pricing) as well. But then you’d think they’d need to offer reasonable access to premium cabin international award seats, too, and y’all know how that has worked out…
