Flight cancellations at Hamburg Airport after a surprise strike by workers affected more than 40,000 passengers on Sunday, a day before a planned wider protest across Germany amid new contract negotiations.

The airport in Germany’s second largest city said the one-day strike, called over pay and conditions, began earlier than expected “without any notice.”

If you're flying to or from Germany, brace yourself—massive flight disruptions are in full swing! Ground handlers walked off the job, leading to widespread cancellations, including several Dubai-bound Emirates flights.
