SAN ANTONIO -

San Antonio International Airport is expecting an increase in passenger traffic over the next few days.

Traffic will get busier than normal starting Thursday due to the Rock 'n' Roll Marathon in San Antonio on Sunday and the Formula One race in Austin on Friday. It's also the start of travel for the holiday season, airport officials said.

The airport is scheduled to receive four charter flights on Thursday and nine on Friday from Mexico for the F1 race in addition to the regularly scheduled flights.

Monday will remain busy as marathoners and race fans depart the Alamo City.

In preparation for the increased traffic, the airport is increasing staff levels in all areas of the airport to assist passengers during the peak periods.

Airport officials are offering the following tips for travelers:

Arrive Early: Passengers should arrive at least two hours prior to their scheduled flight for flights before 7:30 a.m. and 90 minutes for flights thereafter.

Pack with security in mind: Passengers should know what is and isn't allowed in carry-ons and checked luggage. Passengers are encouraged to check the prohibited items list at http://www.tsa.gov/traveler-information.
