Biometric airport security is becoming a more visible part of U.S. travel just as summer demand, World Cup crowds and major-event planning put new pressure on checkpoints. The latest examples came this week at San Diego International Airport and Charlotte Douglas International Airport, where travelers are seeing automated eGates that reduce or replace the traditional identity-check step before physical screening.
The changes are still limited by airport, lane type and eligibility. They do not remove TSA screening, and they do not mean every traveler can walk straight to the X-ray belt. But they are important because they show how the U.S. airport security experience is shifting from a manual document check toward automated identity verification, especially for travelers who already use TSA PreCheck, CLEAR+ or other trusted-traveler tools.
What changed this week
At San Diego International Airport (SAN), CLEAR and TSA opened biometric eGates in Terminal 2 for CLEAR+ travelers. The airport's own security guidance now describes CLEAR+ at Terminal 2 East as an option that lets members use biometric screening, skip the ID check and move directly to physical screening. Axios San Diego reported on June 11 that the San Diego eGates conduct real-time biometric verification by matching a traveler's face with an identity document and boarding pass.
At Charlotte Douglas International Airport (CLT), TSA has rolled out eight self-service electronic gates for TSA PreCheck passengers at Checkpoint 2, according to local reports from WFAE, WCCB Charlotte and Axios Charlotte. The Charlotte test is different from the CLEAR+ model: travelers scan an acceptable identity document themselves, the system checks the credential and facial match, and TSA officers remain part of the process.
Together, the two rollouts matter because they point to the same operational goal: moving identity verification faster while keeping the security screening requirement in place. CLEAR said in its eGate announcement that TSA retains operational control, including security vetting and gate-access decisions, while CLEAR's system transmits limited identity and travel data for the verification process.
Why this matters for U.S. travelers
For travelers, the immediate benefit is not a guarantee of empty checkpoints. The practical value is more modest but still meaningful: less time spent at the podium, fewer manual document handoffs and a smoother path into screening when the technology works as intended.
That can make a difference during peak travel windows. Airports are already dealing with heavy summer demand, and the United States is also hosting FIFA World Cup matches across multiple cities. TSA's June 10 World Cup travel update urged travelers to prepare early, consider TSA PreCheck and use available digital identity options where eligible. eGates fit into that broader effort to move more passengers through existing checkpoint space without simply adding more lanes.
Travelers should still treat the technology as an enhancement, not a substitute for normal planning. Membership programs, digital ID tools and biometric lanes can shorten one part of the trip, but they do not eliminate bag screening, airline check-in cutoffs, airport traffic, parking queues or weather delays. Families, infrequent flyers and travelers with complicated documents should still build in extra time.
Who can use the new lanes
The details vary by airport. At San Diego, the newly highlighted biometric eGate experience is tied to CLEAR+ at Terminal 2 East and requires membership. It can work alongside TSA PreCheck for travelers who have both services, but it is not the same thing as standard PreCheck.
At Charlotte, the eGate test is aimed at TSA PreCheck passengers at Checkpoint 2. Reports from the airport rollout say passengers use a driver's license, state ID, passport or accepted digital ID, while the system verifies the boarding pass, PreCheck eligibility and identity match before the traveler proceeds. Officers remain available to monitor the lane and assist passengers.
The distinction matters for trip planning. A traveler who has CLEAR+ but not PreCheck, a traveler who has PreCheck but not CLEAR+, and a traveler who has neither may see different lane options at the same airport. Even eligible travelers may need to use a regular lane if the eGate is closed, the document is not accepted, the biometric match fails or staffing patterns change.
A bigger airport technology shift
The San Diego and Charlotte updates are part of a wider move toward biometric and self-service processing at U.S. airports. CLEAR announced its eGate pilot in 2025 with initial deployment plans at Hartsfield-Jackson Atlanta International Airport, Ronald Reagan Washington National Airport and Seattle-Tacoma International Airport (SEA), with expansion planned ahead of the World Cup and America's 250th anniversary travel period.
The direction is clear: airports and federal agencies are trying to handle more travelers through constrained terminal spaces. New terminal projects and checkpoint expansions help, but they take years. Identity automation offers a faster operational lever, especially at large hubs where a few seconds per passenger can add up across thousands of daily departures.
There are also consumer questions. Some travelers are comfortable with biometric identity checks if they reduce friction. Others are more cautious about facial matching, data handling and private-company involvement in airport security. CLEAR says it does not access government watchlists or override TSA decisions, but travelers should still understand which program they are using, what data they are providing and whether a non-biometric alternative is available.
What travelers should do before flying
- Check the airport's official security page before departure, because eGate availability can vary by terminal, checkpoint and hour.
- Make sure your ID is valid and acceptable for TSA screening, especially after REAL ID enforcement began in 2025.
- Add your Known Traveler Number to every airline reservation if you use TSA PreCheck.
- Do not assume CLEAR+, TSA PreCheck and Touchless ID are interchangeable; each program has different eligibility and lane access.
- Keep a normal airport buffer during summer and World Cup travel periods, even if you expect to use an expedited lane.
For the U.S. travel market, the takeaway is that airport security is becoming more automated in visible, traveler-facing ways. The new eGates will not solve every checkpoint delay, and their value will depend on reliability, staffing and passenger adoption. But this week's rollouts show that biometric identity processing is no longer just a future airport concept. It is becoming part of the real summer travel experience at major U.S. airports.
