TSA Pre-Check can speed airport security check-in

The nation's homeland security chief is asking fliers to "be patient" amid extremely long airport security lines.

Homeland Security Secretary Jeh Johnson says the government is taking steps to get people onto planes more quickly.

Travelers across the country have endured lengthy lines, some snaking up and down escalators. At some airports, lines during peak hours have topped 90 minutes.

The Transportation Security Administration has fewer screeners and has tightened security procedures.

Airlines and the TSA are already telling fliers to arrive at the airport two hours in advance.

Johnson says the government has a plan to deal with the lines, although travelers should expect to wait as they travel this summer. Whatever the plan, he says, TSA won't neglect its duty to stop terrorists. He says, "We're not going to compromise aviation security in the face of this."

Airlines are expecting a record number of fliers this summer, meaning more passengers and bags to screen.

Johnson said TSA is working with airlines to enforce limits on carry-on bags and their size.

Passengers often over-pack carry-ons to avoid paying the $25 checked bag fee most airlines charge. 

U.S. Sen. Charles Schumer is urging the Transportation Security Administration to put more dogs on the passenger-screening line to reduce long delays for travelers going through security at New York City airports.

The New York Democrat says the highly trained dogs and additional TSA workers would get travelers through the lines more quickly while improving security.

He cited a regional transit authority report that the average maximum wait time for travelers at Kennedy airport in a monthlong period ending April 15 increased 82 percent from the same period last year.

Schumer says the dog teams could cut time spent going through security in half, and he predicted the lines would become even longer and slower without their addition at New York airports, among the busiest in the world.
