Resting Areas
While the airport terminals remain open 24 hours a day, travelers spending the night must remain in the public landside area after TSA security checkpoints close for the evening. Quiet zones and armrest-free bench seating can be found near the stairwells in both terminals and by the ground-floor panoramic windows of Terminal B, with ample electrical outlets nearby.
Baggage and Left Luggage
Due to federal transportation security regulations, there are no luggage lockers or baggage storage facilities at SMF. Overnight travelers must keep their bags with them at all times until their airline check-in desks open in the morning.
Overnight Dining
Most restaurants and shops close shortly after the last departures at night. Food and drink during overnight hours are limited to grab-and-go vending machines and coffee dispensers located landside.
Showers
There are no public shower facilities inside Sacramento International Airport.
Security and Wi-Fi
The airport is patrolled 24/7 by airport police and is considered very safe. Free Wi-Fi operates uninterrupted throughout the night. Bringing earplugs or noise-canceling headphones is advisable due to continuous illumination and recurring security announcements.
