A FIRST FOR AN AIRLINE CARRIER WHICH OPEATES OUT OF TRI CITIES REGIONAL AIRPORT. YESTERDAY AFTERNOON, ALLEGIANT AIR CELEBRATED ITS FIRST FLIGHT TO ST. PETERSBURG/CLEARWATER INTERNATIONAL AIRPORT. AIRPORT MARKETING DIRECTOR MELISSA THOMAS SAYS THE TRI IS HAPPY ABOUT THIS FLIGHT. FOR A LIMITED TIME, ALLEGIANT IS OFFERING FARES FOR 59 DOLLARS ONE WAY. SO DURING THESE HARD ECONOMIC TIMES, THIS ALLOWS PEOPLE TO AFFORD A NICE GETAWAY TO WARMER TEMPERATURES. AGAIN, THE FLIGHTS WILL LEAVE ON THURSDAY’S AND SUNDAY’S.
