Although not formally announced, Airtran has made some schedule changes. Airtran will begin flying ATL-TLH, ATL-PNS, TLH-TPA and TPA-MIA. For people living in PNS and TLH, Airtran will provide some welcome competition to the DL domination. Unfortunately, Airtran will be dropping ATL-VPS. Schedules are loaded and flights can be booked at http://www.airtran.com.
