Southwest-AirTran rolled out its first network connections Jan. 26 and since expanded them. With the two airlines’ schedules fully linked for flights starting April 14, travelers can book flights from a city served by AirTran to almost any city served by Southwest, and vice-versa —- provided they make connections. The link is similar to an airline code-share partnership.
From Atlanta, AirTran and Southwest combined fly nonstop to about 50 cities, but now AirTran passengers can connect to a Southwest flight to get to about 40 more cities.
Meanwhile Hartsfield-Jackson behemoth Delta Air Lines flies nonstop to about 220 destinations from Atlanta.
