Starting today, Frontier Airlines passengers can use TSA PreCheck to move through airport security more quickly.

The Denver-based ultra-low-cost carrier in June announced it had applied to join the program. The Transportation Security Administration said Thursday the airline had been accepted, bringing the total number of airlines that participate in the program to 19.

Ten other carriers flying from Denver International Airport also participate in the program that allows travelers to pass through security with their shoes and belts on and their liquids and laptops still in their bags. Those airlines are Aeromexico, Air Canada, Alaska Airlines, American Airlines, Delta Air Lines, JetBlue Airways, Lufthansa, Southwest Airlines, Sun Country Airlines and

United Airlines

“We hope this new service will help make our passenger’s next journey better,” Frontier’s chief information officer Rick Zeni said in a news release. “We’ve listened to our customers, and we are pleased that we now offer TSA PreCheck.”

Frontier passengers with existing reservations can add their known traveler number to their reservation atflyfrontier.com or see a Team Frontier member at the airport ticket counter the day of their travel, the airline said in a news release. Passengers creating new reservations will have the ability to add their known traveler number at the time of booking.

Passengers can sign up for TSA PreCheck — which costs $85 for five years — at tsa.gov. TSA began aggressively marketing the PreCheck program leading into the busy summer travel season, offering it as part of the solution to clogged lines that stacked up after the agency shed 10 percent of screening agents during a period in which air travel grew by 9 percent.

In a news release Thursday, TSA said in August, 97 percent of PreCheck passengers waited five minutes or less in security lines.
