May 17 - Ashville - $138.80.
Anyway, possibilities are endless. I assume you want to fly soon to get Gold for the remainder of the year - play with Google flights on days you can take off easily. Best to look for flights where the plane turns - you won't miss connection that way. And personally I'd pay a bit more for a shorter flight - FLL/PBI are longer flights, which I'd avoid.
