Security is being stepped up at Kansas City International Airport.

More law enforcement and more police dogs are roaming the airport as we get closer to the tenth anniversary of 9-11. And airport authorities are saying travelers should allow themselves extra time to make their plane, just in case they come across random vehicle security checks. Authorities are investigating what may be a credible terror threat to New York City or the nation's capital days before the 10th anniversary of the Sept. 11 attacks.. But no threats have been made beyond the east coast.
