Ongoing Ukrainian drone strikes targeting the Moscow region have repeatedly triggered temporary suspensions of arrivals and departures at the capital’s four main airports (Sheremetyevo, Domodedovo, Vnukovo, and Zhukovsky) to ensure aviation safety amid air-defense activity. The largest such episode occurred on June 18, 2026, when all facilities closed multiple times during the most intense attack wave reported since the start of full-scale hostilities, delaying or canceling hundreds of flights. Russian authorities have also imposed broader low-altitude flight restrictions over central regions, while international carriers such as EL AL have suspended routes citing airspace risks. Trader sentiment on resolution timing or responsible actor reflects expectations of continued conflict-driven disruptions through summer 2026, with any escalation in strikes or new defensive measures likely to influence short-term probabilities.
