The Orgrimmar Skyway is an unnamed sub-zone inside the orc city of Orgrimmar. It consists of two zeppelin towers, a flight master, a riding trainer, a flying mount vendor and several Orgrimmar Skyway Peons. It was built after the Cataclysm to adapt the city to flying mounts. The zone doesn't currently have a name but is referred to as Orgrimmar Skyway by the peons working there and other NPC's in-game. The quartermasters for Orgrimmar, the Darkspear Trolls, and the Bilgewater Cartel can be found here.
