I'm lucky that Nashville is a Southwest city. We can take advantage of their periodic super sales to Florida .
I haven't tracked Southwest's sales cycle, but there seems to be one offered every year at this time and again in the spring. This week we can book tickets to Tampa for $39 each way, or when all is said and done, around $100 a ticket.
That's cheaper than Greyhound, folks, and it's a nonstop flight.
