Ah! Success! If I do the slightly compressed route (BWI -> MCO, MCO -> IND) I can do it in two chunks for approximately the same price:
$164.40
and
$156.40

Which aint bad in my book. Of course, that leaves me one hop short @ 59. I will toy with it some more since I've got some room to wiggle on either Thursday or Friday. I would love to not have to make another flight just to bounce up and over to 61.

Thanks for your help Andy!!!!!
