CHATTANOOGA — A Delta Air Lines flight from Dayton, Ohio, to Atlanta made an unscheduled landing Monday at Chattanooga with 76 passengers aboard to check out a smell of smoke Monday.

Delta spokesman Trebor Banstetter referred questions about the landing of Flight 926 to the flight operator, Memphis-based Pinnacle Airlines Corp.

Pinnacle spokesman Joe Williams said there was a crew of four and 76 passengers aboard the CRJ 900. No smoke was located.

“We suspect something near the flight attendant’s station,” Williams said. “We will undertake a thorough investigation of that.”

Chattanooga Airport Authority spokeswoman Christina Siebold said the flight made a routine landing.

Banstetter said passengers were transported by bus to Atlanta.
