Has anyone seen reasonable Delta fares that would allow 3 segments to FL from either PHL, BWI, or BDL on a Saturday with 3 segments back to that same city on that same Saturday (thus, no Saturday night requirement).

It would be a very long day, but for the right price, might be worth it. I am not set on FL, but mention it only because of the tendency for lower fares from NE United States to FL. Any other 3-segment down and back itinerary in one day from one of those cities would be of interest.
