CHICAGO -- The Transportation Security Administration is taking steps to shorten the long security lines at O'Hare and Midway airports.

Nearly 60 additional screeners and four more bomb-sniffing dogs will be sent to O'Hare Airport immediately.

In a few days, 100 TSA employees will go from part-time to full-time at the airports. By mid-August, the TSA will assign even more officers to both airports.

But for now, Chicago's airports are still advising fliers to arrive three hours before their departure times.
