The latest two bouts of winter weather which have paralysed airports in the French capital will cost Air France-KLM between €25 and €35 million, the airline’s chief operating officer said.

“Everything that happened over the weekend represents a total of around €15 to €20 million,” Pierre-Henri Gourgeon said on Europe 1 radio.

“We already had an earlier episode a little less severe a couple of weeks ago which accounted for €10 to €15 million,” he added.

Mr Gourgeon apologised to passengers for the disruptions and praised the airline’s employees for doing their utmost to help clients in the difficult situations.
