The Suwałki Gap is the roughly 65-kilometre land corridor linking Poland to Lithuania. It is the only land connection between the three Baltic states (Lithuania, Latvia, Estonia) and the rest of the European Union — to its east is Belarus, to its west is the Russian exclave of Kaliningrad. For anyone monitoring the EU's eastern frontier, the gap is a compact geographic test case: two hostile borders, one narrow passage, and a wind field that frequently moves air from one side to the other.

On AirVeto, the gap is where the orange-border inflow-detection logic pays off most directly. A segment on the Lithuanian-Belarusian frontier turns orange when the wind vector is currently crossing into Lithuania within 85° of the border-normal; a segment on the Polish-Russian frontier turns orange when wind is crossing from Kaliningrad into Poland. Both can happen simultaneously, and when they do, the gap becomes an inflow funnel for airborne objects released on either side.

A narrow corridor also means that a single synoptic system (a passing front, a stationary high) dominates the entire gap. You rarely see the northern end and southern end in genuinely different wind regimes. Kaliningrad's wind field, in particular, is usually correlated with the adjacent Polish-Lithuanian coast — reason enough to read the Polish side of the gap as a proxy for the Kaliningrad interior when that matters.

The gap has been the focal point of repeated airspace conversations in 2025–2026, including smuggling-balloon activity along the Lithuanian-Belarusian portion and airspace closures at Vilnius International Airport (30 km north of the gap's Lithuanian end). The incident archive for Vilnius-area closures lives under /incidents.
