“Asking passengers to arrive three hours early for domestic flights is unacceptable,” said Rep. Bonnie Thompson (D-MS).

Peter Neffenger laid out his plan in front of the Homeland Security Committee. The plan included additional employee training, investing in new technology and a new incident command center.

“One of my fundamental priorities is to dramatically expand the pre-check program and the capability to enroll people in pre-check,” said Neffenger.

Several lawmakers questioned how the former top security operations official received a  $90,000 bonus—given scenes of long lines and strewn baggage in Chicago.

The U.S. Travel Association says long wait times could force Americans to skip travel during the peak summer season – an estimated $4-billion  drain on the economy.

“The whole flying thing is bad. The skies aren’t friendly anymore,” said passenger Bill Mitchell.
