HALIFAX -- Passengers and crew of a Delta Airlines flight that made an emergency landing Wednesday night in Halifax have resumed their trip.

Ashley Gallant, a spokeswoman for the Stanfield International Airport, says the airline sent a new aircraft that took off today en route to Zurich.

Gallant says Delta flight 066 was travelling from Atlanta on Wednesday when it declared an emergency over an "oxygen maintenance issue."

She had no further information about the problem.

Emergency crews were on the scene, but the aircraft landed safely in Halifax around 10:15 p.m.

There were no injuries among the 139 passengers and crew.
