Southwest Airlines today opened booking for the spring. The airline replaced Air Tran here in Charlotte back in April, so this period covers the one-year anniversary of coming to town. There’s no anniversary present from the airline to Charlotte travelers though: the new schedule features the same six flights (2 x Baltimore, 2 x Chicago Midway, 1 x Houston Hobby, 1 x Orlando) that Southwest has offered since April. Not sure that there’s much reason at this point to expect them to add more until Southwest goes into growth mode again.
