Poland's Civil Aviation Authority said Lublin and Rzeszów airports have resumed flight operations

The established pattern in these episodes is a short-duration shutdown, measured in hours, with operations resuming once the threat window passes, so the resumption headline itself marks the de-escalation leg rather than fresh information about intent. The event to track is the closure, not the reopening: prior instances that mattered for markets were those where debris crossed the border or a closure extended beyond the sortie window, shifting the read from precaution to incident. Transmission when it has occurred runs through European defence names, regional aviation and insurance costs, and at the margin the zloty, though moves have historically faded once operations normalise absent physical damage. Worth noting is whether the accompanying closure was described as routine military activity or linked to an identified airspace violation, since official wording has been the reliable tell for whether follow-on diplomatic or NATO process steps are likely.
