Flights to and from Italy are expected to be disrupted by a strike by air traffic controllers on Friday.
A union representing Italian air traffic workers has called for its members to walk out on January 16 from 12.00 to 16.00 GMT.
Easyjet said that all airlines travelling to and from Italy and through Italian airspace will be affected by the four-hour stoppage.
“We are doing everything possible to minimise the impact to our customers and are working through our plans which we will communicate as soon as we can,” said Easyjet.
“If we are forced to cancel any flights, our customers will be informed by SMS and email.”
