The Berlin Brandenburg Airport (BER) is facing unprecedented disruptions due to a warning strike called by 2,000 employees, resulting in all flights being grounded for the day. This rare occurrence follows previous incidents where the airport experienced significant flight cancellations but never a total standstill. Travelers, affected by the cancellation of 445 flight departures, have been encouraged to reschedule their travel plans directly with their airlines, highlighting the massive impact of such labor strikes on passengers.
