LAX officials expect more than 2 million people will travel through the airport from Nov. 22 to Dec. 2, up nearly 7 percent from last year.
That volume of passengers will make LAX the nation's busiest airport during the Thanksgiving holiday, according to online travel website Orbitz.
The airport said there has been an increase in international flights to Asia and Europe, which may have caused the increase in passengers. LAX also pointed to travel experts that said some of the airlines are using larger planes to fit in more travelers.
Airport officials urged passengers with flights during the peak travel times of 6-9 a.m., 11 a.m. to 2 p.m. and 7-11 p.m. to arrive at their airline's ticketing areas two hours earlier for domestic flights and three hours earlier for international flights.
But there is some dispute over the eagerness of Southern Californians to travel during the Thanksgiving holiday.
The Automobile Club of Southern California expects car and air travel to decline four percent during the Thanksgiving holiday. The club said the decline is due to high unemployment, higher tax rates and the increased cost of traveling.
Filomena Andre, the club's vice president of travel, said consumers know it's more expensive to travel during the holidays compared to non-peak times of the year.
"Many of our members are opting to take leisure trips when they can get more value for their vacation dollar," Andre said.
