If you want a trip, we did:
DFW-MIA, MIA-LAX and LAX-STL over a weekend, using NETSAVER fare on AA.COM with stay overnight Friday in MIA. We returned Monday and Monday night again in MIA. I first called Customer service to see if you had to stay in MIA or LAX, no just along as I met the fare rules.
So for those of you outside DFW, you could buy one to DFW and then fly out from DFW to another point and return the same way using NETSAVER fares.
