Fliers told to be vigilant

Passengers traveling through O’Hare and Midway international airports are advised to allow plenty of time to get through security in the wake of Osama Bin Laden’s death.

The U.S. Department of Homeland Security said fliers can expect bag checks, random screenings at gates, canine teams and other safety measures.

Travelers are also asked to be watchful of any suspicious activity and report it to authorities.

Homeland Security officials did not issue a domestic terrorism alert following Bin Laden’s death Sunday, although the U.S. State Department put out an international travel alert for people traveling and living abroad to be aware of the potential for anti-American violence.

“The Transportation Security Administration continually evaluates the latest threats and screening measures, which are implemented based on the latest intelligence,” a TSA official said.

The Chicago Department of Aviation said passengers should, as always, arrive two hours in advance of flights.

Authorities at Metra said the agency was in contact with the Department of Homeland Security and local law enforcement regarding any security issues.
