Sure it is, but everyone flies to Lakeland! Seriously, though, my arrival into FL was going to be in the middle of the day Saturday, not during the arrival window for Sun-n-Fun.
Likewise, my departure on Sunday would have to be too early to leave out of Lakeland - as the air shows wouldn't be over yet. So I usually find it more conducive to my plans to fly into Clearwater and rent a car instead.
Besides, Clearwater has a beach! :)
