I dont believe LAL
has a terminal. I could be wrong.
Every year the Sun N' Fun fly-in happens and LAL
becomes the busiest airport in the nation with hundreds of movements a day. Gates could be found easy and maybe erect a tent like Skybus has in St. Augustine until a terminal could be built. Lakeland could make a great destination for those airlines looking for a out of major city market. Tampa is only 45mins going W on I-4. Orlando is probably 1 1/2H east on I-4. Not to mention Lakeland is a beautiful town.
