According to Aviation24.be and Reuters, a Belarusian smuggling balloon triggered a closure of Vilnius International Airport on a Tuesday evening in early 2026, affecting approximately 700 passengers. Three flights were diverted to Riga and two to Kaunas. The date recorded here is 10 February 2026 — a Tuesday in the 7–14 February window as characterised by Aviation24.be — but primary source confirmation of the precise date is pending; the operational details (Tuesday evening, ~700 passengers, three to Riga, two to Kaunas) are also consistent with a late-January 2026 closure, possibly 27 January 2026. AirVeto will update this page when the exact date is confirmed. AirVeto's wind reconstruction at 700 hPa covers the Vilnius approach corridor during this window. Lithuania balloon page · methodology
Note on date: The "Tuesday evening in February" characterisation is sourced from Aviation24.be. The operational details — ~700 passengers, three diversions to Riga, two to Kaunas — also correspond to a Tuesday-evening event in late January 2026. The precise date has not been confirmed by a primary Lithuanian source. If you have primary source documentation of the exact date, contact AirVeto.

Another Vilnius airport closure — a recurring pattern
By early 2026, Vilnius airport had experienced multiple balloon-induced closures. This event confirmed that the Vilnius approach corridor was subject to repeated disruption from balloon crossings, not isolated incidents — the source's characterisation of it as "the second of 2026" may reflect the count at a specific point in January or February, but multiple closures had occurred across the first weeks of the year.
The airport serves Lithuania's capital and handles approximately 5–6 million passengers per year. Tuesday evening closures affect business and leisure travel connecting Vilnius to Western European hubs; the five diversions to Riga and Kaunas represent full re-routings, not simple holds.
700 passengers affected — three to Riga, two to Kaunas
The approximately 700 passengers affected were distributed across the diverted flights. Riga received three aircraft — the logical diversion airport for Baltic capacity, given its runway length and proximity — and Kaunas received two. Kaunas is Lithuania's second city and has a functional international terminal, making it a standard overflow point for Vilnius diversions.
Lithuania's aviation authority issued a NOTAM closing the Vilnius TMA after the balloon was detected entering Lithuanian airspace from the direction of Belarus. The closure duration — estimated from the "Tuesday evening" descriptor at Aviation24.be — appears to have been 2–4 hours based on the diversion count and the operational pattern of earlier Vilnius closures.
Vilnius sits directly under the main Belarusian balloon corridor
Vilnius International Airport lies at the edge of the Baltic–Belarus balloon corridor. The balloons are launched from eastern Belarus, carried westward by the dominant easterly or northeasterly synoptic flow at 3,000 m, and cross into Lithuanian airspace along the corridor that passes over or near Vilnius. The airport's approach paths, which extend northeast from the runway, overlap directly with the probable inbound balloon tracks.
Lithuania's civil-aviation authority established a protocol following the first 2026 closure requiring immediate NOTAM issuance and airport suspension upon detection of an uncontrolled object in the approach corridor. The February closure was the first execution of that protocol at scale.
Wind layer — 700 hPa over Vilnius on the estimated closure evening
