General aviation, too, saw a decrease in November, with a 3.3% decrease in operations, from 12,885 to 12,464.
An airport spokeswoman said there didn't seem to be one factor in particular that led to the drop in activity.
The decrease in total travelers was split about evenly between domestic and international passengers, Rachel Gibson wrote in an email, and this year to date, traffic has "grown steadily."
"We expect that JWA will serve more total passengers in 2013 than we did in 2012," she wrote.
According to the report, so far this year, the number of total passengers to board and deplane at JWA has increased by 4%, from 8,122,318 January through November 2012, to 8,443,447 January 2013 through last month.
Officials have said that the airport is not, however, expected to hit its 10.8-million annual passenger cap — part of the operating restrictions set in the JWA settlement agreement between the county, which operates the airport, the city of Newport Beach and local advocacy groups who hoped to limit the airport's noise on neighboring residents.
Total operations may increase again next year, as county officials court airlines to offer direct flights to Hawaii, Washington, D.C., and Mexico. Earlier this month, the Orange County Board of Supervisors approved a $1.3-million incentive package in an effort to attract carriers.
In June, airport director Alan Murphy told members of the Newport Beach business community that reinstating service to Hawaii and adding flights to D.C. were top priorities.
He called D.C. JWA's "No. 1 current unserved market."
