Jetstar has no grounds for appeal against a ruling allowing pilots and cabin crew on trans-Tasman and Pacific flights to take breaks, the Supreme Court says.
The Employment Court ruled last year in favour of pilot Robert Greenslade, who said he was not able to take his breaks because the turnaround between flights was too short.
In its appeal, the budget airline argued it was bound by Australian laws, which did not provide compulsory meal breaks.
Earlier this year, the Court of Appeal ruled the company must follow New Zealand laws.
The airline had asked the Supreme Court for leave to appeal that ruling on the question of whether the law refers to rest breaks to be taken during or between work periods.
The Supreme Court said Jetstar's interpretation appeared strained and there were no grounds for appeal.
