PBI is a smaller airport; it looks like my best choices tend to be PBI -> ATL -> Anywhere. I also frequently fly out of FLL – it's a longer drive, but worth it for better flight options at times (e.g. FLL-SEA direct on Alaska.) I also like Delta's program insofar as miles not expiring. When I fly American, I credit those miles to Alaska. I try to avoid United, but I do have a FF account with them.
