Keep your belt on!

Southwest Airline’s frequent-flyer members need no longer undress to pass airport security. Today, the carrier became the eighth domestic airline to offer TSA PreCheck, a program to pre-approve travelers for expedited security screenings.

The president of the US Travel Association, Roger Dow, calls the initiative “decidedly pro-traveler.” It’s meant to make travel easy, so that people fly—and fly often.

By the end of December, Pre-Check will be available to all members of the military at every airport in the country offering the service. At this time, military personnel can enjoy the perk at 10 domestic airports.

In addition to leaving on belts and jackets, travelers participating in PreCheck can also keep their 3-1-1 bags and laptops packed. Best of all, they’ll breeze through security without walking barefoot.
