LOS ANGELES, Nov. 21 (Xinhua) -- Los Angeles International Airport (LAX) on Wednesday urged travelers to come early as a record 2.52 million travelers are expected to pass through the airport over an 11-day Thanksgiving travel period.

This number is a 4.25 percent increase over last year's 2.42 million passengers.

"It's #ThanksgivingWeek, & once again, we're breaking records when it comes to holiday travel," the airport authority tweeted, adding some tips to travelers, the first of which is to arrive at least two hours before any domestic flights and three hours before international flights.

LAX said even though the holiday will officially start on Friday and end on Monday, but Wednesday would be the third busiest day during the holiday since about 244,000 people are anticipated to pass through the airport.

The busiest day at the airport will be the Monday after Thanksgiving, with 251,000 travelers expected. The second busiest day will be Sunday, where nearly 249,000 people will travel.

The slowest days are expected to be Thanksgiving and Black Friday, where between 183,000 and 206,000 people will travel, LAX predicted.

According to a report issued earlier this month by the American Automobile Association, in Los Angeles a total of 4.2 million people are expected to get away for the long weekend, of whom about 3.6 million will travel on the road.

California Department of Transportation also warned Wednesday that residents travelling in Los Angeles and Ventura counties near the Woolsey Fire burn area be careful.

As a rain storm is also expected to hit the region sometime Wednesday evening, there may be rocks, debris and mud that end up on the roadways in those areas.
