Spirit Airlines’s biometric bag drop with photo-matching. Limiting touchpoints and unnecessary face-to-face interactions will change the way airports operate.” Now in 2020, we’re realizing those same elements are just as valuable when it comes to helping people feel comfortable flying. “We knew early on that automation and biometric photo-matching would make the check-in process smoother. “We started looking at ways to improve the check-in experience in 2019 as part of our pledge to invest in the guest,” Spirit President and CEO Ted Christie said in a press release. Passengers can save time and reduce contact. Spirit Airlines’s new biometric protocol for domestic air travel begins with customers tagging their checked bags and then sending them to the aircraft through an automated self-bag drop unit featuring biometric photo-matching. According to Spirit Airlines, the carrier is the first to make biometric check-in assistance available for domestic passengers. A year later, Spirit Airlines launched this new biometric experience at New York’s LaGuardia Airport and Chicago O’Hare International Airport.

In 2019, the Florida-based airline began to develop this biometric solution for domestic flights. Spirit Airlines, known for its ultra low-cost fares, became the first in the United States to implement a biometric photo-matching solution.
