Flying Through Busy US Airports? Here's How CLEAR Can Help Speed Up Security at Atlanta, Denver, JFK and Other Major Hubs

MundoTrip | Travel News | 25 July 2026

CLEAR is helping eligible travelers move through airport identity verification more quickly at many of the busiest airports in the United States. While the service does not replace TSA security screening, it can reduce the time spent waiting for document checks at airports such as Atlanta, Denver, New York JFK, Dallas/Fort Worth and Los Angeles, especially during peak travel periods.

For millions of Americans flying each year, getting through airport security is often one of the most time-consuming parts of the journey. As passenger numbers continue to grow at major U.S. airports, more frequent travelers are turning to CLEAR, a biometric identity verification service that helps eligible members move more quickly to the TSA security checkpoint. The service is available at many of the country's busiest airports, including Hartsfield-Jackson Atlanta International Airport (ATL), Denver International Airport (DEN), John F. Kennedy International Airport (JFK), Dallas/Fort Worth International Airport (DFW) and Los Angeles International Airport (LAX). While CLEAR can make the airport experience more efficient, travelers should know that it does not replace TSA screening. Instead, it speeds up the identity verification process before passengers proceed through the normal TSA security checkpoint.​​​​​​​

How CLEAR Works at Airport Security

CLEAR uses biometric technology, including fingerprint or iris recognition, to verify a traveler's identity instead of requiring a boarding pass and photo identification at the initial document check. After identity verification is completed, members are escorted directly to the TSA screening area, where they must still undergo the same physical security screening as every other passenger. Travelers who also have TSA PreCheck can use both programs together at participating airports, allowing them to complete identity verification more quickly before entering the TSA PreCheck screening lane. The service is designed to improve efficiency, but actual wait-time savings depend on passenger volume, staffing levels and airport operations on the day of travel.

Atlanta, Denver and JFK Remain Among the Busiest Airports for Frequent Flyers

CLEAR is especially valuable at some of the nation's busiest airports, where long security lines are common during peak travel periods. Hartsfield-Jackson Atlanta International Airport continues to rank as the world's busiest airport by passenger traffic, while Denver International Airport, Dallas/Fort Worth International Airport, Chicago O'Hare International Airport and New York's John F. Kennedy International Airport also handle tens of millions of passengers every year. Because these airports experience heavy passenger traffic throughout the year, expedited identity verification services such as CLEAR can be particularly useful for business travelers, frequent flyers and passengers with tight connections. However, there is no official ranking showing that one airport consistently delivers greater CLEAR time savings than another, as wait times vary throughout the day.

CLEAR Wait Time Benefits Depend on Airport Conditions

Is CLEAR Worth It for Frequent Travelers?

For travelers who regularly fly through large hub airports, CLEAR may provide a more consistent airport experience by reducing the time spent waiting for identity verification before security screening. It is particularly useful for passengers departing from airports with high passenger volumes, including Atlanta, Denver, Dallas/Fort Worth, Los Angeles, Orlando, Seattle and New York JFK. However, travelers who fly only occasionally or primarily use smaller regional airports should check whether CLEAR is available at both their departure and arrival airports before deciding whether the service fits their travel needs.

Why This Matters for US Travelers

As airports continue to welcome record numbers of passengers, efficient security screening has become increasingly important for both business and leisure travelers. Services such as CLEAR can help eligible passengers move more smoothly through the identity verification process, especially at large hub airports where security lines are often busiest. While the service does not allow travelers to skip TSA screening, it can reduce the time spent reaching the checkpoint and make the overall airport experience more predictable for frequent flyers. Understanding how CLEAR works and where it is available can help travelers choose the best option before their next trip.
