Quick summary
A Turkish Airlines Airbus A330-300 operating flight TK407 departed Istanbul Airport at 2:22 a.m. on September 20, 2026, entered Russian airspace, then reversed course and returned to Istanbul after a large-scale drone attack forced Rosaviatsia to impose temporary flight restrictions on all four Moscow airports. At least 35 Turkish-carrier flights to and from Vnukovo International Airport were delayed or cancelled during the disruption window.
The restrictions covered Sheremetyevo, Domodedovo, Vnukovo, and Zhukovsky simultaneously — Moscow’s entire air hub, not just one airport. Vnukovo alone logged 69 delayed arrivals, 60 delayed departures, and 11 cancellations before operations resumed on revised schedules later that morning.
A widebody jet already inside Russian airspace doesn’t often turn around. On Sunday morning, one did.
Turkish Airlines flight TK407 — an Airbus A330-300 — lifted off from Istanbul Airport at 2:22 a.m. local time on September 20, 2026, bound for Vnukovo International Airport in Moscow. The aircraft crossed into Russian airspace and was on approach when it changed course and flew back to Istanbul. Passengers did not reach Moscow on that service.
The cause was a coordinated drone attack on Moscow and surrounding regions. Moscow Mayor Sergei Sobyanin stated that Russian air defense systems intercepted more than 1,600 drones across the country since Saturday, with roughly 450 approaching the capital. In response, Rosaviatsia — Russia’s federal air transport agency — imposed temporary flight restrictions across all four Moscow airports: Sheremetyevo, Domodedovo, Vnukovo, and Zhukovsky. The restrictions were lifted on the morning of September 20, but not before the damage to schedules was done.
For travelers holding tickets on Istanbul–Moscow services that day, the practical result was hours of uncertainty, overnight stays in Istanbul, and a scramble for seats on later departures once the airspace reopened.
How Moscow’s entire air hub shut down at once
The scale of the disruption at Vnukovo tells the story clearly. Airport operational data showed 69 delayed arrivals, 60 delayed departures, and 11 outright cancellations during the restriction window, according to reporting by Airways Magazine citing the airport press service and Rosaviatsia. More than ten inbound aircraft were rerouted to alternate aerodromes for refueling before continuing to Moscow once restrictions lifted — TK407’s return to Istanbul was the most dramatic outcome, but it was part of a broader, coordinated safety response.
Inbound flights from Istanbul, Dalaman, Dubai, Tashkent, Chelyabinsk, and Yekaterinburg were among those either diverted or held during the window. The suspension of aircraft reception and departures at Domodedovo and Zhukovsky ran in parallel with the Vnukovo restrictions, confirming that no Moscow airport offered a clean alternative during the peak disruption period.
| Airport | Delayed arrivals | Delayed departures | Cancellations | Status |
|---|---|---|---|---|
| Vnukovo (VKO) | 69 | 60 | 11 | Restrictions lifted morning of Sep 20 |
| Sheremetyevo (SVO) | Data pending | Data pending | Data pending | Restrictions imposed and lifted Sep 20 |
| Domodedovo (DME) | Data pending | Data pending | Data pending | Operations suspended, resumed Sep 20 |
| Zhukovsky (ZIA) | Data pending | Data pending | Data pending | Operations suspended, resumed Sep 20 |
Flight tracking data, confirmed by Turkish and international media via Social News XYZ, shows TK407 completed its return to Istanbul safely. Whether the turnback was triggered by a formal Vnukovo closure notice, broader airspace risk assessment, or Turkish Airlines’ own operational discretion remains unconfirmed — the single-source claim pointing specifically to a Vnukovo closure has not been independently verified by Eurocontrol or Rosaviatsia.
Why Istanbul connections carry more risk than travelers realize
The Istanbul–Moscow corridor is one of the few remaining high-volume Europe–Russia gateways where a major network carrier still operates multiple daily widebody and narrowbody services. That concentration matters when things go wrong.
When Rosaviatsia imposes simultaneous restrictions across all four Moscow airports — as happened here — Turkish carriers face a compounding problem: aircraft rotations stall, crew duty-time clocks keep running, and the connecting banks at Istanbul that feed onward traffic to Europe, the Middle East, and Asia start to fray. Same-day seat availability on the corridor tightens fast, and travelers who miss their Moscow arrival can find themselves pushed onto itineraries that add a full day or more to their journey.
The wrinkle for Western travelers is that Istanbul is a major transit hub for Asia-Pacific connections. A disrupted Istanbul–Moscow bank doesn’t just affect Russia-bound passengers — it can ripple into onward seat availability across the network. Anyone building an itinerary through Istanbul with a tight connection window is exposed to this risk whenever drone activity spikes near Moscow.
This incident is not an isolated anomaly. Moscow’s airports have faced repeated drone-related disruptions since the Russia-Ukraine conflict escalated, and the pattern — temporary Rosaviatsia restrictions, diversions to alternate aerodromes, schedule recovery on revised timetables — has become a recognizable operational response rather than a surprise. The question for travelers is not whether it will happen again, but when.

Steps to protect your trip on Turkey–Russia routes
Moscow airspace remains an active risk zone — Rosaviatsia can impose restrictions with minimal notice, and all four Moscow airports can be affected simultaneously, leaving no clean alternate within the city.
- Check flight status before leaving for the airport. TK407 was already airborne when the situation developed, but many disruptions begin on the ground. Monitor the Turkish Airlines app or website for gate and status changes in the hours before departure.
- Hold flexible fares on Istanbul–Moscow tickets. Fares that allow same-day changes without heavy penalties give you options when a flight returns to origin or a departure is held indefinitely. Rigid economy tickets on this corridor carry real risk right now.
- Build buffer time into Istanbul connections. If you are transiting Istanbul to Moscow — or connecting onward from Istanbul after a Moscow leg — a single-connection itinerary with a tight layover is a liability. Add at least three to four hours where possible.
- Know your rebooking rights before you fly. Turkish Airlines’ conditions of carriage govern what happens when a flight returns to origin due to airspace restrictions. Understand whether your ticket entitles you to a full reroute, a refund, or hotel accommodation in Istanbul before you board.
- Consider whether Moscow travel is necessary right now. Government travel advisories from the US State Department, UK FCDO, and Australian DFAT all carry active guidance on Russia. Tour operator marketing does not override government intelligence.
Watch: Rosaviatsia’s next restriction notice — if drone activity near Moscow intensifies through late September, expect further simultaneous closures across all four airports, with Turkish Airlines and other carriers adjusting or suspending services on short notice.

Questions? Answers.
Was Turkish Airlines TK407 the only flight affected, or did other international carriers also divert?
Reports confirm that inbound flights from multiple origins — including Dubai, Tashkent, Dalaman, and domestic Russian cities — were diverted or held during the restriction window. More than ten inbound aircraft were sent to alternate aerodromes. Whether other European or international carriers suspended Moscow services during the same period has not been fully confirmed.
What compensation are passengers entitled to when a flight returns to its origin due to airspace restrictions?
This depends on your ticket type and departure region. Under EU Regulation 261/2004, a return to origin caused by extraordinary circumstances — which airspace closures from conflict activity typically qualify as — generally exempts the airline from paying the standard delay or cancellation compensation. However, the airline remains obligated to offer you a choice between a full refund or rebooking on the next available flight, plus meals and accommodation if an overnight stay is required. Check your specific fare conditions and contact Turkish Airlines directly.
Are all four Moscow airports likely to be restricted simultaneously in future incidents?
The September 20 event confirms that Rosaviatsia’s security protocol covers all four Moscow airports — Sheremetyevo, Domodedovo, Vnukovo, and Zhukovsky — at once when drone activity reaches a threshold near the capital. There is no Moscow airport that functions as a guaranteed safe alternate during these windows. Travelers should plan accordingly.
How does this affect travelers connecting through Istanbul to Asia-Pacific destinations?
A disrupted Istanbul–Moscow bank reduces seat availability across Turkish Airlines’ connecting network at Istanbul Airport. If your Asia-Pacific itinerary routes through Istanbul with a Moscow leg, a TK407-style return can cascade into missed onward connections. Build buffer time into Istanbul transits and hold flexible fares when Moscow is part of the routing.
