These Are the Most High-Tech Airports in America

Sacramento International Airport

• Passengers Per Year: 4.9 Million

• Green terminals have heat-reflecting roofs and “low-E glass”—which reflects heat. Both are part of the reason why Terminal B achieved LEED silver status.

• “Common-use gate system” allows any airline to operate out of any gate. Passengers can also use any kiosk in the airport to print boarding passes or find flight information.

• WebTrak allows citizens living near the airport to view aircraft flight operations and also collects information on noise levels to help better protect the local communities.

• Free WiFi.
