Hello, I would like to get from OKC to ORD, stay one night in Chicago, and then go on to MIA and return to OKC a week later. I have Southwest and AA miles or could pay for the flights. Does anyone know of a relatively cheap way to do this other than just paying regular miles or cash for three one-ways. I could also leave from TUL, DAL, DFW, XNA, or ICT. Thanks in advance, Lisa
