I get that.

But I was responding to the poster who said that "Frontier has to have an aircraft at CVG for the Apple flights to CUN and PUJ. They had been doing this by repo, but that was expensive and it's obviously cheaper to shift the DAY flights to CVG."

[emphasis mine]

The implication is that shifting the DAY flights to CVG avoids the repo move. So again, given the DEN-CVG schedule, how does Frontier avoid the repo move?

The answer, so far, seems to be that they don't avoid a repo move. So all I'm saying is that avoiding a repo move is not a reason for the shift. I'm not knocking their decision, though.
