A suspicious package that disrupted the travel plans of 2,500 passengers at Will Rogers World Airport turned out to contain a bullhorn that played Christmas music.

The security alert caused frustration and anger among travelers who waited for hours Friday while the airport was evacuated partially and flights were delayed. The owner of the package was questioned but not arrested.

The Oklahoma City police bomb squad used water cannons to blow apart the package found in the baggage claim area about 9:15 a.m. The all-clear was given about 2 p.m.

No flights left the airport for more than 3½ hours, and many passengers waited five hours or more as they were told to rebook flights and were shuffled from one line to the next by airport officials and Transportation Security Administration employees.
