Resurrected thread. But I've encountered an issue since the recent revamp of Dl.dumb. In the past, using ITA or Kayak, I could find creative routes, pairings, lower fare buckets, etc. I'd always been able to reproduce on DL.dumb by using multi-city and building my flights by schedule.

Now this is not working. I'm only able to capture the fare when going through Kayak to Delta.dumb. Not an issue as I can just input my SkyMiles number from there--HOWEVER, if I want to do Pay with Miles, when I go through Kayak, that option doesn't appear in the purchase phase.

As an example, I looked at a trip for 10/6/14 on Kayak.
Cle-atl-sfo-MSP. Dl 963/1680/2105. Bookable.

Can't even construct it on Dl.dumb. Gives error message.

Anyone else experience this?
