KNOXVILLE, Tenn. (WVLT) -- There were few, if any flight delays at McGhee Tyson Airport Christmas night after an attempted terrorist attack that afternoon.

Metropolitan Knoxville Airport Authority officials said the few delays East Tennessee travelers experienced on Christmas were related to bad weather along the east coast.

The Department of Homeland Security did not raised the national threat level on Christmas after a Nigerian man claiming to have acted on instructions from al-Qaida, tried to detonate an explosive device on a Detroit-bound passenger jet.

Though the national threat level remains at “Orange,” the Transportation Security Administration released a statement early Friday evening saying, “passengers may notice additional screening measures put into place to ensure the safety of the traveling public on domestic and international flights."

The bottom line for East Tennessee travelers is that if you are flying over the next few days, you should get to the airport an hour to an hour and a half before your flight.
