WASHINGTON, -- Airport security screeners are about to begin opening hundreds of thousands of pieces of checked baggage every day, but key questions about security and liability have not been resolved, government officials and airline and airport executives say.
The Transportation Security Administration, created by Congress a year ago, is supposed to screen all checked baggage for bombs beginning Jan. 1, but the two main ways it will do the job require that many bags be opened. Among the unresolved issues is how screeners would open locked bags, who would be responsible if a traveler claimed that something inside was stolen or damaged, and who would have to get the bag to its owner if the security search caused the bag to miss the flight.
“It’s a fairly big problem,” said Randall H. Walker, director of aviation at McCarran International Airport in Las Vegas.
At the moment, Mr. Walker said, his first concern is “chaos in my terminal” because screeners will not be able to process bags fast enough. The percentage of bags screened is supposed to rise to 100 by Jan. 1.
The airlines, which sometimes spend more than $100 to deliver a suitcase to the owner if the bag misses the original flight, are particularly concerned with who would pay if the missed flight was the fault of security and not the airline. But another issue is the new procedure for searching bags, largely out of the owner’s presence.
The issue is so sensitive that there is even debate over who will tell the public. The airlines believe that the solution is for passengers not to lock their bags, but they want the government to announce that to the public. The airlines also want the government to tell travelers that it is the government, and not the airlines, that will be conducting the searches.
The airlines and airports are hoping that Congress will extend the Dec. 31 deadline in at least some places. But the liability and logistical issues will exist in at least some places even if the Transportation Security Administration gets extensions at some airports. Most of the problems from liability to logistics require decisions from the security agency, but airline and airport executives concede that their are no easy solutions.
Before the 2001 terrorist attacks, very few bags were opened, and the Federal Aviation Administration, which was then in charge of security, required that the owner be summoned to open the bag, to reduce the risk of a security guard being hurt by a booby trap. But under the system now evolving, many bags will be opened out of view of the passenger, in back rooms where luggage is sorted for loading on airplanes.
In fact, the preferred solution at most airports is to put the screeners and their equipment in the back rooms, where the conveyor belts carry the bags on their way to the planes.
“Those bag rooms aren’t big enough for the bags, let alone all the people they’d put down there,” said Todd Hauptli, a spokesman for the American Association of Airport Executives. “And there’s a whole lot of bags that need to be opened up.”
The performance of the screening machines is a loosely guarded secret. The machines that scan whole bags at a time are said to reject 25 to 30 percent of them; those machines measure the density of objects inside, and sometimes cannot distinguish between explosives and chocolate.
Most of the bags rejected by these machines must then be opened.
The other main system is called trace detection, in which a technician rubs a gauze pad over objects to be tested, and then feeds the pad to a machine that analyzes it for explosive traces. These are becoming familiar to travelers at the passenger checkpoints.
For checked baggage, the Transportation Security Administration plans to rub the outside of 40 percent of the bags, rub the pad briefly over the inside in 40 percent of the bags, and rub down objects inside the bag in the last 20 percent; that means opening 60 percent of the bags.
