Jetstar takes fatigue extremely seriously and actively encourages any cabin crew member to report any instances of fatigue. Jetstar rejects claims that it forces cabin crew to operate when fatigued.

Jetstar has the same high standards of fatigue management as the rest of the Qantas Group.

Jetstar has a strong and effective fatigue management system in place and has invested significantly in this area in line with a global best practice management approach.

Safety is our number one priority and we have an open culture of reporting issues. If a member of our crew is too fatigued, then they should not operate the flight, and we communicate this openly.

Jetstar rosters all duties including cabin crew in accordance with the duty limitations and minimum rest periods specified in the relevant Enterprise Bargaining Agreement/s, or other contract/s, negotiated with and agreed to by the various representative bodies.

Jetstar Group CEO Bruce Buchanan spoke to ABC News on the issue this morning.
