A surprise strike by ground staff at Hamburg Airport has led to the cancellation of over 80 flights, affecting more than 40,000 passengers. This strike began a day earlier than scheduled and is part of a larger labor action expected to disrupt operations across 13 German airports, including major hubs such as Frankfurt and Berlin. As travelers prepare for widespread cancellations, unions warn that up to 3,400 flights could be scrapped nationwide, impacting around half a million people. Airlines, including Lufthansa, Air France, and easyJet, are bracing for chaos, and travelers are advised to check their flight status amid the disruptions.
