Flights to and from Portugal are being threatened with cancellations and delays due to a general strike across the country from tomorrow (Wednesday).
The industrial action is expected to affect airports from 9pm and run until 4am on Friday with a national shutdown planned for Thursday.
Eurocontrol, the European air traffic organisation, warned that the start and end of strike times would be different across air traffic control zones and airports in Portugal. Several unions representing aviation workers announced that they will join the general strike disrupting travel.
Portuguese airport operator ANA said passengers expecting to fly after 10pm on November 23 or any time the next day should contact their airline or travel agent before heading to any airport in the country.
The Portuguese Civil Aviation Pilots Union (SPAC) announced last week an eight-day strike scheduled for December 9, 10, 11, and 12 and January 3, 4, 5 and 6.
