Sacramento International Airport is preparing for its busiest ever Thanksgiving travel period. Sacramento International Airport estimates the two busiest days this Thanksgiving will be Wednesday and Sunday, with approximately 40,000 passengers on each day. Sacramento International Airport plans to use uniformed officers to direct traffic during holiday peak travel periods. For those picking up or dropping off passengers, you can stop circling the airport and save gas -- 30 minutes of free parking is offered in Hourly parking on the bottom floor of the Terminal A parking garage, and in the Hourly B parking lot. The airlines at Sacramento International Airport recommend arriving 2 hours early for domestic flights and 3 hours early for international flights. And be sure to check your airline’s baggage restrictions, for both carry-on and checked luggage, before coming to the airport. The airlines strictly enforce these limits, especially during the busy holiday season.
