Denver International Airport and the Transportation Security Administration introduced two new TSA PreCheck Touchless ID lanes as part of the new West and East Security Checkpoints.

These limited-access lanes use facial recognition technology for what DIA officials said is faster, more efficient identity verification.

The lanes are specifically for TSA PreCheck flyers —an expedited security screening program that is offered at some U.S. airports.

To use the new technology, PreCheck flyers must have an active airline profile with a participating airline and valid passport information on file. Users also need to opt in to the new facial screening program.

By opting in, travelers can move through either of the new lanes using only their face to confirm their identity, airport officials announced.

Airlines participating in the feature include American Airlines, Delta Air Lines, United Airlines and Alaska Airlines.

“We are pleased to be among a select group of airports in the U.S. rolling out this new option for TSA PreCheck travelers for a quicker, more convenient screening experience,” CEO Phil Washington said in a press release. “We are grateful for our partnership with TSA and their commitment to improving the security screening process for travelers while maintaining the highest levels of safety and security.”

The new East and West checkpoints are part of a broader airport construction project called the Great Hall Program.

Airport officials said that since the opening of the West Checkpoint in February, security wait times have gone down.

DIA has most recently seen an average of just under 4 minutes of wait time at West Security Checkpoint and an average of just more than 10 minutes at the South Security Checkpoint, which was the primary screening location through Aug. 4, according to a spokesperson.

Prior to the West checkpoints opening, DIA said the average wait time during the fourth quarter of 2023 was seven minutes at the South Checkpoint, five minutes at the North Checkpoint, and just under nine minutes at the A-Bridge Checkpoint.

“Customer satisfaction survey results have increased our score for ease of going through security by 13% from the time period leading up to the checkpoint opening on West and the waiting time for security screening improved by 19%,” Washington said at the East Checkpoint opening Monday.

Airport officials said that with the opening of the newest East Checkpoint, DIA travelers may see those wait times decrease more in the near future.

The East security lines opened Tuesday.
