Air New Zealand (ANZ) and Continental Airlines have applied to authorities to start a code-sharing agreement.
"The code-share is planned to commence in March subject to regulatory approvals," says an ANZ spokeswoman.
The carrier plans to code-share on Continental's Los Angeles-New York and Houston-Cleveland services, she adds.
Continental will code-share on ANZ's transpacific services and selected domestic and trans-Tasman flights, says the spokeswoman.
