I was on the Song website this AM checking flights for April 04 from Boston to Orlando. I filled out my info and the available flights and prices came up. I wonder what would happen it I changed the passenger number. "?" I changed it from 4 to 1 and the prices went down on certain flights - as much as $100. I don't know why or if this is common, but it may be cheaper to reserve your flights one at a time.
