Jetstar chief operating officer Gerry Turner will join chief executive Gareth Evans in departing the low-cost carrier as a broader executive reshuffle gets underway.

Mr Turner handed in his notice last week, calling it quits just over a year since he took on the operations job at Jetstar and after 20 years working at parent group Qantas. He will leave the business in October, shortly before chief executive Mr Evans finishes in December, as was announced to the ASX late last week.
