Feds Offer Simpler Flight Screening Plan

Airplanes line the runway at LaGuardia Airport in this June 8, 2007 file photo in New York. U.S. airline delays are at their highest level in at least 13 years, and analysts say fliers can expect more of the same for the rest of the summer. The Department of Transportation on Monday, Aug. 6, 2007 said the industry's on-time performance in the first six months of the year was its worst since 1995, the earliest period for which the agency has comparable data.

The Homeland Security chief said he was unaware of any specific, credible threat against airlines. But based on recent car bomb attempts in Great Britain and public statements by terrorists, he repeated his view that "we are entering a period where the threat is somewhat heightened."

"Look at the history of al-Qaida," Chertoff said. "The airplane has been a consistent favorite target of theirs."

On the domestic side, transferring watch-list checks to Transportation Security Administration officers "should provide more security and more consistency, and thus reduce misidentifications" that have frustrated passengers, Chertoff said.

Existing screening has been widely ridiculed because people like Sen. Edward M. Kennedy, D-Mass., other members of Congress and even infants have been blocked from boarding or delayed because their names are similar to names on the lists.

Chertoff said the new domestic system will avoid activities envisioned earlier that raised privacy concerns.

"Secure Flight will not harm personal passenger privacy," Chertoff said. "It won't collect commercial data (about passengers). It will not assign risk scores and will not attempt to predict behaviors."

Such plans alarmed Congress so much that it barred implementing the program until it passed 10 tests to ensure privacy and accuracy. The Government Accountability Office, Congress' auditing arm, found the previous version failed almost all of them.

Currently, only a passenger's full name is required when reservations are made although date of birth and gender usually become known to transportation security officers later in the boarding process.

Transportation Security Administrator Kip Hawley said volunteering those two items earlier would reduce misidentifications in watch-list matching.

"With the full name, we can resolve 95 percent of the cases correctly. The date of birth adds 3.5 percent to that, and the gender adds another one percent," Hawley said.

Privacy advocates like Dempsey and Bruce Schneier, chief technology officer at the security company BT Counterpane, also were pleased with limits on how long most records will be kept. A check that produces no match _ which will be the case for the vast majority of travelers _ would be kept only seven days. A false positive match would be kept seven years. Confirmed matches would be kept 99 years.

"On the surface, it looks pretty good," Schneier said. "I'm cautiously optimistic. It's nice to see some common sense."
