Air New Zealand has sold its cabin interiors and corporate jet fitout business, saying it has "divested at the right time".
Altitude Aerospace Interiors worked on the airline's "cuddle class" seats, interiors for other airlines and faced tough competition for work in the large business jet market.
The airline has sold the fitout business to AIM Aviation, a British-based airline interiors company.
Air NZ's chief financial officer, Rob McDonald, said the airline was satisfied the transaction would provide a "strong foundation" for both companies to leverage the relationships they had with aircraft manufacturers and airline customers.
