CHICAGO -

Air travelers over the age of 75 soon may not have to remove their shoes or light jackets to clear security in a test program at four U.S. airports. 

The Transportation Security Administration announced the change Wednesday. It's one of several new procedures meant to speed lower-risk passengers through screening and will likely mean fewer pat-downs for older travelers. 

Late last year, the federal agency made similar changes for travelers ages 12 and younger at some airports. 

The new procedures will begin March 19 at Chicago's O'Hare International Airport, Denver International, Orlando International and Portland International. 

Airport security is a common complaint of travelers. Many of them say the TSA doesn't use common sense when it screens all air travelers the same way, including young children and the elderly.
