In that city there have been around 100 confirmed cases of the virus which has killed more than 130 people throughout China.
"I think passengers should be assured the situation is being very closely monitored and very well managed at an international level," said Johnston.
He said the airline was being updated regularly on new developments from the International Air Transport Association which had access to the latest developments by the World Health Organisation.
Passengers who were feeling unwell before flying should contact their doctor for advice, he said.
"If a customer is unwell in flight our cabin crew are very well trained to deal with a range of medical conditions and they have medical equipment on board to be able to assist."
Crew had access to protective gear such as masks and gloves and were trained to deal with a range of medical conditions. They could also contact medical specialists around the world.
"Aircraft have very sophisticated cabin air conditioning systems that filter out organisms such as viruses from the air that is recirculated through the cabin," he said.
Cleaning agents used at the end of a flight were effective against viruses such as the coronavirus.

When the Sars outbreak hit in 2003 there were no direct flights between New Zealand and China. Then about 70,000 visitors from China came to New Zealand but this has grown to more than 400,000 a year.
That surge reflects the big increase in outbound travel from China and the challenge for health authorities to contain the outbreak.
In 2003, about 20 million people travelled overseas from the country while this has now grown to more than 150 million a year.
