Shreveport Airport Authority officials will hold a couple of meetings tomorrow to give area contractors an overview of future airport projects and explain how to do business with the airport.  Those meetings will be held in the third floor conference room at Shreveport Regional Airport.  There'll be one at 10:30 tomorrow morning for former and current airport contractors and another at 1:30 for prospective contractors.  City officials will be on hand, too, to answer questions.
