Balloons close Vilnius airport for almost seven hours

Vilnius International Airport (IATA: VNO, ICAO: EYVI) suspended operations from 22:30 on April 9, 2026 to 05:15 on April 10, 2026 local time, a stretch of close to seven hours, after objects consistent with smuggling balloons entered civil aviation flight zones on the Lithuanian-Belarusian border. The overnight restriction was extended into the early morning before flights resumed, with night flights delayed, diverted, or cancelled for security reasons. AirVeto's reconstruction of the ICON wind field at 3,000 m at 22:00 UTC on April 9, 2026 shows westward flow at 30–45 km/h across the Lithuanian-Belarusian border - the direction and speed consistent with drift from Belarusian territory toward the Vilnius approach zone during the closure window.

The airport sits roughly 30 km west of the Belarusian border. REFORM.news counted the March 21-22 disruption as the fourth at Vilnius Airport in 2026 linked to balloons, and reported that the previous closure before this one came on March 31. By March 22, Lithuania had intercepted 45 balloons carrying contraband cigarettes from Belarus since the start of the year, REFORM.news reported. AirVeto's reconstructed archive, which tracks this airport's closures rather than every reported disruption, counts April 9 as the second, after the January 28 incursion.

What AirVeto showed during the closure window

At 3 km across the Lithuanian-Belarusian border, AirVeto’s view at the relevant window was reading westward flow (grid centre 87°, range 73°–101°) at 30–45 km/h — the direction that drifts anything aloft on the Belarusian side onto the Vilnius approach. At 500 m, the altitude most relevant for low-floating balloons, the direction held but the speed dropped to 8–12 kt: a drift time of roughly 1.5a 2–3 hour drift time acrossndash;2 hours across the 30 km border-to-airport distance, consistent with objects entering the approach airspace through the overnight window.

Multiple border segments on the Lithuanian-Belarusian frontier sat orange across the window. Orange is the inflow-alert state: wind crossing into the EU within 85° of the border-normal — the geometric condition under which an object released on the upwind side is physically able to cross. When Vilnius shut, AirVeto’s view said exactly why.

AirVeto's reconstruction is based on reporting by REFORM.news and Nasha Niva, and on AirVeto's wind-model data for the closure window.

This was one in a run of balloon disruptions on the Vilnius Airport approach in 2026 — see the 13 May Kaunas Šančiai recovery further inland.
