The US Transportation Security Administration (TSA) will expand its PreCheck screening programme to a further 28 airports in the US in 2012 to allow for faster security lines.
The programme, trialed earlier in seven pilot airports in the country, will allow travellers to pass quickly through pre-flight security screening if they volunteer to disclose their personal information in advance.
PreCheck has been tested for several months with frequent travellers at major gateway airports and 336,000 passengers have been screened so far.
The initiative allows TSA officials to focus on passengers that have not disclosed their information while speeding up screening procedures for passengers who have already voluntarily provided personal information prior to boarding.
After TSA confirms the eligibility of the passenger, they will be authorised for faster screening as the information is embedded in the barcode of the passenger's boarding pass, which will allow access to a separate TSA PreCheck lane.
At the TSA PreCheck lane, passengers are screened without the usual removal of shoes, laptops from bags, light outerwear, jackets or belts.
TSA administrator John Pistole said: "TSA PreCheck moves us closer to our goal of delivering the most effective and efficient screening by recognising that most passengers do not pose a threat to security."
"We are pleased to expand this important effort, in collaboration with our airline and airport partners, as we move away from a one-size-fits-all approach to a more intelligence-driven, risk-based transportation security system," Pistole said.
TSA PreCheck is currently in service at airports in Dallas, Miami, Las Vegas, Minneapolis, Los Angeles, Atlanta and Detroit.
The further airports which will deploy PreCheck include Baltimore/Washington International Thurgood Marshall Airport (BWI), Boston Logan International Airport (BOS), Charlotte Douglas International Airport (CLT), Cincinnati/Northern Kentucky International Airport (CVG), Denver International Airport (DEN) and Fort Lauderdale-Hollywood International Airport (FLL).
PreCheck will also be implemented at George Bush Intercontinental Airport (IAH), Honolulu International Airport (HNL), Indianapolis International Airport (IND), John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), Lambert-St. Louis International Airport (STL) and Louis Armstrong New Orleans International Airport (MSY) among others.
TSA stated that it will continue expanding PreCheck to further airlines and airports once they are ready.
TSA is currently testing various screening initiatives, including initiatives that have been developed to facilitate positive ID verification for airline pilots and the implementation of expanded behaviour detection techniques following the agency's risk-based security initiative.
