American Airlines will drop its Auckland-Los Angeles service for eight weeks later this year.
It will drop flights between August 7 and October 6.
"This eight-week suspension is in line with the airline's peak season in North America,'' it said.
American began flying the route to Auckland last June around the time competitor United Airlines did. United has also dropped its daily service between Auckland and San Francisco from April 18 to October 30.
The temporary withdrawal of flights will dent the travel market which had seen double-digit growth between the two countries in the past year. Intense competition between the US carriers and Air New Zealand had driven down fares.
