400+ Moscow Flights Delayed After Temporary Airport Closures

More than 400 flights were delayed across Moscow’s main air hub after temporary overnight restrictions briefly halted arrivals and departures at the capital’s four key airports, leaving airlines to rebuild schedules through Sunday.

What happened at Moscow’s airports

Published coverage indicates that Sheremetyevo, Vnukovo, Domodedovo, and Zhukovsky airports introduced temporary restrictions on aircraft movements overnight into Sunday, September 20, 2026. While the restrictions were later lifted, the interruption created a backlog that carried into the day’s flight program.

Delays accumulated quickly because aircraft and crews were displaced during the closure window, and some incoming flights were held or rerouted before they could land in Moscow. Even after airspace operations resumed, airport and airline networks had to sequence late arrivals, reposition aircraft, and comply with crew duty-time limits, which can prolong disruptions for hours.

By midday, airport departure boards and compiled tallies reported more than 400 delayed flights across the four-airport system, along with a smaller number of cancellations. Sheremetyevo, Russia’s busiest airport, showed the largest concentration of disruptions.

How many flights were affected (airport-by-airport)

Publicly available flight-board data summarized by Russian business media showed Sheremetyevo with 121 delayed arrivals and 126 delayed departures since the start of the day, with roughly 35 flights marked cancelled. The same reporting showed Vnukovo with 69 delayed arrivals, 60 delayed departures, and 11 cancellations.

At Domodedovo, reports indicated at least 27 delayed arrivals and one cancellation. Zhukovsky, the smallest of the four airports in the Moscow area, showed several delays and two cancellations in the same period, contributing to the overall count that exceeded 400 delayed flights across the hub.

Because these figures rely on real-time boards, they can shift throughout the day as airlines consolidate flights, swap aircraft, or convert cancellations into later departures. Travelers typically see the effects in rolling waves, with later flights sometimes delayed to accommodate earlier disruptions.

Diversions to other cities added to the backlog

Coverage also described a diversion pattern during the restriction window, with more than 30 aircraft approaching Moscow landing at alternate airports rather than holding in the air. Diversions were reported to cities including Nizhny Novgorod, Kazan, St. Petersburg, Samara, Cheboksary, and Nizhnekamsk, depending on routing and available parking capacity.

Nizhny Novgorod’s Chkalov Airport was described as a major diversion point, receiving a large share of Moscow-bound flights while restrictions were in place. Diversions like these can cause a second layer of delay: aircraft need new takeoff slots, crews may time out, and passengers may remain on the ground waiting for onward clearance.

For travelers, diversions can also mean arriving at a different airport than planned and then waiting for a continuation flight, a bus transfer, or a rebooking, depending on airline decisions and the aircraft’s ability to return to Moscow quickly.

What it means for travelers: rebooking, connections, and airport timing

Airlines serving Moscow adjusted schedules as the airports worked through accumulated delays. Reports highlighted that major Russian carriers including Aeroflot and low-cost operator Pobeda revised timetables, which can affect onward connections inside Russia and to international destinations served from the Moscow hub.

Passengers with tight connections are typically the most exposed when a hub experiences a multi-airport disruption. A delayed arrival into Sheremetyevo or Vnukovo can cascade into missed onward flights, particularly on domestic routes that operate less frequently than before 2022, or on international services that may have limited seat availability for same-day reaccommodation.

Travelers departing Moscow on disruption days generally benefit from checking their flight status shortly before leaving for the airport and again en route, since departure times can change repeatedly as carriers reshuffle aircraft rotations. When restrictions lift, airports may look “open” while gate assignments, baggage flows, and boarding windows remain uneven for several hours.

Why Moscow closures can ripple quickly across Russia’s network

Moscow’s four-airport system functions as Russia’s primary connecting complex, so even a brief pause can propagate across the country’s flight network. When inbound aircraft are delayed or diverted, they cannot operate their next scheduled leg on time, and the resulting aircraft-mismatch can affect routes far beyond Moscow.

Disruptions are magnified when multiple airports in the same metro area impose restrictions simultaneously. Aircraft that might normally divert between Sheremetyevo, Domodedovo, and Vnukovo may have fewer immediate options, forcing longer reroutes and increasing the number of passengers caught in rebooking queues.

As airports and airlines restore normal sequencing, travelers may continue to see knock-on effects into later departures, especially on routes that depend on a single daily rotation. For those traveling to or via Moscow, the most practical near-term approach is to monitor airline notifications, confirm baggage rules for rebooked itineraries, and allow extra time for airport processing while flight banks normalize.
