If we add in reasonable travel time to and from the airport and plan to arrive well in time for the flight, that would add two or three house, which would still essentially be a full consulting day versus a saving of $5000.
Origin is actually DTW, not DLH. Yes, it's probably not the best example since there are no DTW-DLH flights and they require a connection in MSP. I probably should have used non-stop filter in Google Flights to save transit time. For example, DTW-TPA roundtrip booking below. If you really want to save time, you could just look up fare filings on ExpertFlyer and feed them to an agent to book them (although that's not nearly as interesting).
