A Delta Air Lines flight bound for Atlanta has returned to Buffalo, New York, after the crew received an indication of a possible issue with one of its two engines.
The airline says Flight 1672 landed safely at Buffalo Niagara International Airport on Thursday morning and maintenance technicians are evaluating the aircraft.
The flight had 174 passengers and five crew members on board.
It comes a day after a SkyWest flight from Chicago to Connecticut made an emergency landing in Buffalo after three passengers on board lost consciousness. One passenger described a lack of air in the cabin and shortness of breath, but the airline said an inspection on the ground found no mechanical faults.
