Air France said it would be forced to ground one of its new Boeing 787 aircraft and reduce its flight frequency from Paris to Guangzhou, China over a disagreement with its main pilot union the SNPL about pilot training. The news comes as Air France is locked in a wider conflict with its unions over pay: the airline group has launched a company-wide staff consultation on its latest pay proposal in a bid to break the deadlock, but 3 unions have called for a further 4 days of strike action May 3, 4, 7 and 8, which would bring the total number of days of strike action in recent weeks to 15. From May 2, the carrier will operate 3X-weekly to Guangzhou from its Charles de Gaulle hub, instead of 5, using a Boeing 777 on the route to replace the 787, a spokesman said. <br/>
