1. Overview: Icy rain stops Berlin departures
Freezing, icy rain at Berlin Brandenburg Airport (BER) brought many departures to a halt in 2026 because de-icing operations were strongly hindered. While landings continued to be possible, passengers were warned to expect flight cancellations and delays. The Deutscher Wetterdienst (DWD) issued warnings from Wednesday evening about black ice and extreme conditions lasting into Thursday, and authorities reported isolated flight cancellations even as a spokesman stressed that starts and landings were ‘largely normal’.
Weather timing and immediate effects
The DWD warning began Wednesday evening and covered a period of extreme conditions through Thursday. The main immediate effect at BER was a backlog in departures because crews could not safely complete aircraft de-icing in the expected time, which created knock-on delays and a number of cancelled services.
2. How icy rain affects airport operations
Icy rain and freezing precipitation create two main hazards for airports: black ice on surfaces and contamination of critical aircraft surfaces. De-icing becomes a bottleneck when flights cannot leave on schedule because each aircraft requires safe, certified removal of ice and anti-icing treatment before departure. Aviation.Direct specifically reported significant delays in the handling chain with de-icing identified as a critical winter bottleneck.
- De-icing delays increase aircraft turnaround times, reducing the number of flights that can depart.
- Ground handling and gate availability are affected as aircraft occupy stands longer.
- Late departures can cascade into further cancellations or long delays later in the day.
- Even when landings remain possible, the flow of departing aircraft is the limiting factor for operations.
3. Advice for passengers and travelers
Passengers planning travel through Berlin during icy rain should prepare for disruption. Expect possible cancellations or long delays, and keep communication channels with your airline or travel provider open. Check flight status frequently and follow any instructions from airport staff.
- Monitor official airline notifications and the airport information displays.
- Allow extra time for ground processes if travel is unavoidable.
- Have flexible plans: be ready to rebook or accept alternative routings if your departure is cancelled.
Special note for U.S. travelers
U.S. travelers received warnings about potential flight disruptions in Europe from similar weather events. If you are traveling from or through Berlin, pay attention to advisories and confirm international connections in case of cancellations that affect onward travel.

5. What authorities and airlines say
Officials balanced safety and continuity: the DWD issued weather warnings about black ice and extreme conditions, while airport spokespeople noted that, despite problems with departures, starts and landings were largely proceeding normally. Aviation reports highlighted de-icing as a critical operational constraint in winter weather. Travelers are encouraged to remain patient and follow official guidance while airlines and airport teams work to restore normal operations.
