Air New Zealand is in talks with other airlines wanting to use its new "cuddle-class" economy seats.
The airline's first Boeing 777-300ER aircraft will land in Auckland on Christmas Eve, including new economy Skycouch seating, on which couples can lie down.
Air New Zealand chief executive Rob Fyfe said new premium economy
Spaceseats on the aircraft would redefine that class of travel.
More than 30 airlines had been in contact with Air New Zealand and its seat manufacturers about the new seats, Fyfe said.
Formal negotiations were under way with carriers from Asia, North America and Europe to licence the seats after Air New Zealand had 18 months of exclusive use, he said.
The 338-seat aircraft will have 60 economy seats which can create 20 Skycouch combinations.
For two adults, the Skycouch will be based on buying two seats at standard prices with the third seat at half price.
