The coronavirus epidemic will have a only a marginal impact on global travel demand and the airline industry is healthy enough to absorb any economic slowdown in China, the chief executive of Aer Lingus parent IAG said today. 

Dozens of airlines have suspended flights to China in response to the worsening health emergency that has killed close to 500, nearly all in the country.

A meeting of international aviation officials in Singapore has also been cancelled. 

"The aviation industry is very robust. We may see some marginal impact," IAG CEO Willie Walsh told reporters in Doha at a CAPA aviation summit. 

British Airways, which is owned by IAG, has suspended flights between London Heathrow and Beijing and Shanghai, which Walsh said represented around 1% of the airline's capacity. 

There had been no impact on the group's other airlines, including Aer Lingus and Spain's Iberia, as they do not fly to China. 

Willie Walsh, who steps down in March, said he did not expect the virus to deter people from travelling. 

Asked if the industry was healthy enough to absorb a downturn in China's economy, he said: "without question" adding that airlines were more capable of responding to economic shocks than in the past. 

Qatar Airways, which owns a minority stake in IAG, has also cancelled passenger flights to China.

However its chief executive said that was because other countries had placed entry restrictions on those who had recently visited China. 

Akbar al-Baker said that made it difficult to staff China flights because those staff would not be able to operate flights to some other countries for some time afterwards. 

A global airline lobby, the International Air Transport Association said it was too early to say how much the virus would impact the industry this year but is confident of a recovery.  

"This industry has demonstrated its ability to overcome these type of difficult events and overcome them successfully," chief executive Alexandre de Juniac told Reuters.
