Northwest spokesman Kurt Ebenhoch told the Blade that when the two airlines entered into a ticket swap agreement, Air New Zealand's letter for reciprocal benefits stated the tickets would be for a fellow employee, dependent child or "spouse."
Because of this wording, his company was forced to decline to redeem the tickets.
He said Northwest was in compliance with California law by insisting on the specific "domestic partner" definition when redeeming tickets.
But Air New Zealand spokeswoman Lucy Powell told the newspaper the wording on its letter was "for yourself and your spouse".
"Our definition of spouse includes same-sex couples. I guess it all comes down to the interpretation of 'spouse."
Mr Anders, who receives domestic partner benefits through Air New Zealand, said all he wanted was the prize he won.
