Sorry if this is already covered. My searching did not reveal an answer. Is there a way to search -- either using delta.com or a paid service -- for the cheapest fare that can be upgraded with miles? Delta.com allows searching for specific fare codes, but is there one that is always the cheapest? I see some posts about "K" fares -- is that the best to search for or do you have to search code by code?
Edit: Oh, wait, I think I understand. It's "K or higher," which I suppose would do it. Sorry. I'll leave this up in case others have a similar question unless a mod wants to delete.
