LOS ANGELES (CNS) — Officials at Los Angeles International Airport estimated that the 19-day holiday period will see a 9.5-percent increase in passenger traffic over the same period in 2015, despite a number of delays due to a flight order issued by the Federal Aviation Administration.

The holiday period — which runs from Dec. 16 through Jan. 3, 2017 — will see an estimated 4.3 million travelers pass through LAX, an additional 400,000 passengers over last year’s total of 3.9 million, according to Los Angeles World Airport spokeswoman Katherine Alvarado.

The busiest days this holiday period were Dec. 21 and Dec. 23, with passenger totals nearing 239,000 travelers, according to Alvarado. The slowest days were Christmas Eve and Christmas Day, and New Year’s Eve was also expected to be lighter with an estimated 198,000 travelers, well under the daily average of 221,000 passengers.

LAX is the seventh-busiest airport in the world and the third-busiest in the United States.
