United Airlines has increased its frequency between Auckland and San Francisco to daily and the All Blacks test in Chicago has already proved a winner for the airline.
United says it has benefited from strong demand from rugby fans travelling to this weekend's test against Ireland in what can be a soft month.
''November is not usually a peak month but with the All Blacks they (flights) are absolutely jam packed,'' said Julie Reid, United's director of sales Australia and New Zealand.
The airline has also put a bigger plane on the route, a Boeing 777 to replace the 787-8 it has flown five times a week since the beginning of July as part of a revenue-sharing deal with Air New Zealand.
Reid said the bigger aircraft would provide about 50 extra seats and would be used on the route throughout summer.
