Was flying into ATL today and heard something new that I haven't heard in the 4 years i've been based here as an ASA pilot. Maybe some of you Delta or AirTran guys can shed some light. We were on the Honie arival coming in and assigned 9R....we heard 2 Delta flights and 1 AirTran be told to fly the 8L transition procedure???? Huh? I've never heard that, is it something new? Company specific???
