The Polish-Belarusian border runs for approximately 418 kilometres, from the northeast at the tri-border with Lithuania to the southeast at the tri-border with Ukraine. It is the EU's longest land frontier with Belarus and has been the focal point of migration, airspace, and cross-border incident reporting since the 2021 migration crisis. The Podlaskie Voivodeship, around Białystok, is the middle section — and the one most frequently referenced in recent airspace events.
On AirVeto, the Polish side of the Belarusian frontier is where orange inflow segments surface during the recurring cross-border balloon and drone reports. The 85° border-normal threshold is particularly informative here because the border runs broadly north-south, so easterly wind components are directly compatible with inflow — as opposed to, for example, the Lithuanian-Belarusian frontier where the border turns and the wind-geometry relationship is more varied.
Incidents along this frontier include the Christmas 2025 window in Podlaskie (see the incident archive), repeated drone and balloon reports throughout 2025 and 2026, and a standing Polish military presence. The live map at this hub deep-links the AirVeto view to the segment centred on the Białystok area.
