Recurrent Ukrainian drone incursions have driven repeated temporary flight restrictions at Moscow’s four main airports—Vnukovo, Sheremetyevo, Domodedovo, and Zhukovsky—through Rosaviatsia airspace measures for safety during air defense operations. In October and November 2026, authorities reported multiple large-scale attacks, including record barrages exceeding several hundred UAVs, with Moscow Mayor Sergei Sobyanin citing dozens to hundreds intercepted in single nights and resulting delays or cancellations affecting hundreds of flights. These episodes align with broader patterns of Ukrainian long-range strikes on Russian infrastructure, prompting frequent ground stops and “Kover” protocols. Ongoing conflict dynamics, including potential escalations or de-escalation signals, continue to shape trader assessments of the primary suspension cause.
