Vienna Airport Suspends Operations Amid Heavy Snowfall

Heavy snowfall forced a temporary suspension of flight operations at Vienna International Airport (VIE) on February 20, 2026, leading to widespread disruption. The airport halted all takeoffs and landings as winter service teams worked to clear runways and taxiways, resulting in the cancellation of 150 flights and the diversion of numerous inbound aircraft.

The operational halt significantly impacted passengers and airlines, particularly Austria's flag carrier. According to a statement from Austrian Airlines (AUA), the carrier had to cancel approximately 100 flights, affecting an estimated 13,000 passengers. The disruption underscores the vulnerability of major European hubs to severe weather events and highlights the critical nature of airport winter operations.

Operational Response and Impact

Vienna Airport authorities initiated a comprehensive snow removal plan as approximately 20 cm of fresh snow accumulated. An airport spokesperson confirmed that more than 200 employees and over 100 specialized vehicles were deployed for the clearing effort. The scale of the operation was substantial, with crews removing over 1,000 truckloads of snow, totaling around 15,000 tons, from critical airside surfaces.

In a statement, airport spokesperson Peter Kleemann outlined the timeline for resuming service. "From our perspective, individual takeoffs should be possible again from 12 noon, with landings resuming from 1 pm," he stated. This targeted timeline allowed Air Traffic Control (ATC) to begin sequencing departures and arrivals as runway conditions improved. The airport emphasized its commitment to safety throughout the disruption, with a spokesperson noting, "We are doing everything we can to minimize disruptions for travelers. Safety remains our top priority."

Both the airport and airlines advised passengers to check their flight status online before traveling to the airport to avoid unnecessary congestion in the terminals. This proactive communication strategy is a key component of modern air travel disruption management.

Regulatory and Safety Context

The decision to suspend operations is guided by strict safety regulations set by bodies like the European Union Aviation Safety Agency (EASA). EASA's aerodrome regulations mandate procedures for winter operations to ensure runways provide adequate friction for braking and that all markings are visible. The core principle governing flight in these conditions is the "Clean Aircraft Concept," an International Civil Aviation Organization (ICAO) standard which requires all critical surfaces of an aircraft—wings, tail, and control surfaces—to be completely free of snow and ice contamination before takeoff.

Snow and ice accumulation can dangerously disrupt airflow, reducing lift and increasing drag. Consequently, aircraft de-icing and anti-icing procedures are mandatory safety steps. Airlines must adhere to approved ground programs that detail these procedures, ensuring aircraft are protected from contamination until they are airborne.

Vienna Airport's Operational Scale

The weather event impacted one of Europe's significant air traffic hubs. According to official figures from the airport operator, Flughafen Wien AG, Vienna Airport handled 32.6 million passengers in the full year 2025. Recent data shows the airport processed 1,910,186 passengers in January 2026 alone, illustrating the daily volume of travelers affected by such a closure. The airport's winter service is prepared for these events, with a total of around 500 employees and a large vehicle fleet on standby to clear over 2.5 million square meters of operational surfaces. Further details on airport performance can be found in Vienna Airport's official press releases.

Why This Matters

This incident at Vienna Airport serves as a critical reminder of the operational challenges that severe weather poses to the aviation industry. It highlights the necessity for airports to invest in robust and rapid-response winter service teams and equipment. For airlines, such events create significant logistical and financial strain due to cancellations, diversions, and passenger re-accommodation. The event reinforces that despite technological advancements, weather remains a powerful and unpredictable factor in maintaining the safety and efficiency of global air travel.
