I will only have carry-ons, so that should at least make it a BIT easier.
I will be boarding in LAS and flying to MKE, so I will definitely be missing that first leg (DEN to LAS).
So, Brian, what's your advice? Give it a run and complain if it doesn't work? Or call back, say the last person screwed up in booking my ticket and ask that they knock that first leg off?
