Speaking in Sydney this week, Jetstar CIO, Stephen Tame, said the upgrade will affect Jetstar's head offices and executives from December this year.

Tame said Jetstar's motivation for the deployment of Lync, Microsoft's unified communications and collaboration platform, was prompted by the airline's move to a new head office.

"One of the choices we had was around our corporate system. [Do you use] the traditional systems from Cisco and other traditional types of manufacturers, or do you push yourself into the software world where everything is based in the Cloud or as a managed service? That's one of the things that we looked to when we put Lync into the business," he said.

Tame said he had set up corporate Skype and Google accounts in the past, but the communications offerings didn't provide Jetstar with enough flexibility or functionality.
