How are you searching for cheapest city pairs across multiple dates/trip duration?
I'm not hunting for this particular one, but if I were, I'd be using ITA Matrix (
Matrix - ITA Software by Google), Nearby cites and Calendar (with a range of dates).
I might experiment with the above to using Nearby on just one end at a time. Or maybe just list the cities possible for me in the Departing From and/or Destination. And when I could see some cities pairs that could work, I'd try different ranges of dates.
The one thing I'd do is do it NOW. Those things go away really fast. Then I'd book immediately, remembering that Delta has 24 hour cancellation for me to think more deeply. And the 24 hours really is until midnight of the second day.
