French strike causes flight chaos across Europe
Authorities warn of '14,000 hours' of delays as French air traffic controllers strike again
French air traffic controllers have begun a six-day strike which is likely to delay or cancel flights to France or through the country's airspace.
According to the Daily Telegraph, union members have timed the strike, which was called "in protest at budget cuts", to coincide with the presentation of France's aviation budget in Brussels on 30 June.
French aviation authorities have ordered a 20 per cent reduction in air traffic over the next week, forcing airlines to rearrange their schedules.
EasyJet has cancelled 28 services and British Airways called off flights from Heathrow to Lyon, Toulouse and Marseille, The Guardian reports.
More cancellations are expected, with airlines saying that services will be reviewed on "a day-by-day" basis.
Ryanair advised passengers to "check the status of their journey on its website" before departure, and easyJet promised to provide information via "text messages and [the airline's] flight-tracker tool".
"Eurocontrol, a European air safety organisation, estimated the action would cause 830,000 minutes, or almost 14,000 hours, of delays," the Telegraph reports.
