Staffing shortages led to more flight delays at airports across the U.S. as the federal government shutdown stretched into a seventh day.

TAMPA, Fla. - The Tampa International Airport plans to spend $1 million on biometric face scanners by 2020. The new technology will be used on passengers boarding outbound international flights. ABC Action News got a look at the new technology as passengers boarded a flight to Panama City on Friday. As a passenger walks towards the biometric scanner, the device will scan their face and compare it to a database. By 2020, Tampa International Airport will have the face-scanning technology at all 10 gates where passengers are leaving the country on international flights.
