People who carry prohibited items for medical needs - such as cough syrup, insulin, contact lens solution and breast milk or baby formula - will also be directed to the family lanes, the TSA said.
"Expanding these lanes to every airport and directing families and passengers with medically necessary liquids to them, increases passenger convenience and security," TSA Administrator Kip Hawley said in a statement Monday.
In August 2006, the TSA changed its screening policies after officials foiled a plot to use liquid explosives to blow up commercial airlines headed toward the U.S. Intelligence officials remain concerned that terrorists could carry liquid explosives onto planes.
The government is testing equipment that scans liquids for explosives and hopes to lift the restriction in the future.
