Airports Across U.S. Step Up Security Ahead of July 4 Weekend: 'You Have to Be Alert 24/7'

Airports are taking extra security steps for the July 4 holiday weekend.

Airports across America are taking extra security steps as the July 4 holiday weekend draws near, keeping the recent Istanbul terror attack in mind.   

AAA predicts 43 million people will be on the move  by auto, train and plane. That figure beats a mark set in 2007.

“You have to be alert 24/7,” she said.

Flyers should also be prepared for longer lines than usual.

“With the bombings in Turkey, you're going to have nervous passengers, you're going to have heightened security, so it's just a recipe for longer lines and more stress,” she said.

“They're recommending to go to the airport for a domestic flight  two hours ahead, three hours for international. But now with the bombings and the holiday weekend, you want to add an extra hour to that,” she added.

“Wouldn't you rather sit at the airport, have a drink, have something to eat or read, or be part of the stress of worrying about missing your flight?”

AAA said there will be an increased police presence on the road, with cops on the lookout for distracted drivers and drunk drivers, as well as seatbelt checks.
