Air New Zealand says it will introduce sleep pods for economy passengers on its Boeing 787 Dreamliners by the end of 2024.
The Skynest was first unveiled two years ago.
It will consist of six sleep pods, which will be stacked. The pods will each have a lie-flat bed, a privacy curtain and USB charging.
Economy and Premium passengers will be able to book a four-hour slot in a pod for an additional fee. Crew will change the bed linen between slots.
Prices for the fourh-hour slots have yet to be announced. Passengers will be limited to one per flight.
Air New Zealand already offers the Skycouch, where a row of economy seats can be turned into a bed for two.
