DALLAS — A Southwest Airlines flight from Houston to Dallas has been canceled after a passenger spotted a box cutter in the plane’s overhead bin.

Southwest spokeswoman Olga Romero says a passenger on the scheduled 6:15 a.m. flight today from Houston’s Hobby Airport found the box cutter and turned it over to the crew.

The captain alerted airport security. All 97 passengers were taken off the plane and re-screened.

The plane was searched, but no other hazards were found.

Romero says the passengers were booked onto other flights and have arrived in Dallas.

A Transportation Security Administration spokesman says the airline made the decision to cancel the flight and that operations at Hobby Airport are normal.
