Funny stuff.   Looking at flights from Minneapolis to Philadelphia and this doozy of a flight popped up.  It was the cheapest option.

You simply can't argue with a value like that.  You get to fly from Minnesota to North Carolina to Rhode Island to Michigan and then finally to Philadelphia.  What a bargin for a flight that costs less than $1000.
