Business and leisure flights over the Kainuu–Koillismaa corridor in northern Finland returned to their customary routings on 22 February 2026 when the temporary restricted airspace EFR643 Ketola was de-activated at 21:59 UTC. The two-week restriction, authorised by the Finnish Transport and Communications Agency (Traficom) and published as AIP Supplement 008/2026, had barred civil aircraft from surface level up to flight-level 70 while the Finnish Defence Forces conducted large-scale unmanned-aerial-vehicle (UAV) and live-fire exercises. Military, border-guard, customs and emergency-service flights were exempt, but all other operators—including corporate shuttle, air-cargo and regional passenger carriers—were required to file avoidance routings approved by the Airspace Management Cell. Although the blockout measured fewer than 35 nautical miles at its widest point, it sat astride two popular north-south ATS routes linking Helsinki and Tampere ACC sectors to Lapland’s mines, data centres and tourist resorts. Finnair’s Rovaniemi, Kittilä and Ivalo services, for example, added roughly six minutes of flying time and required additional fuel uplift, while air-freight charters to Kaunis Iron in Sweden and Boliden Kevitsa in Sodankylä were re-filed via waypoints KELMU and LUMSI to remain clear of the danger area. Ground-handling firms at Helsinki-Vantaa report that many business-jet operators chose evening slots on 22 February to take advantage of the reopening, allowing same-day turnarounds that would otherwise have required costly overnight crew layovers.

For crews and passengers who suddenly find themselves rerouting through Finland because of such last-minute airspace changes, VisaHQ can expedite any required Finnish visas or travel authorizations online, providing real-time status updates and courier support so that paperwork never becomes the reason a flight is delayed.

According to Baltic Control ATS, requests for off-route clearances dropped from an average of 42 per day during the restriction to just seven on 23 February, highlighting the operational burden the closure imposed. While Traficom stresses that short-notice exercises are essential for national security and for testing counter-drone systems, it also acknowledges the commercial impact. A post-exercise debrief with airlines and the Finnish Business Aviation Association is scheduled for mid-March; topics will include earlier NOTAM lead-times and the possibility of publishing contingency SIDs/STARs in the national eAIP so that operators can integrate them into flight-planning software in advance. For global-mobility managers, the episode is a reminder that Finland’s airspace—generally known for predictable slot availability—can experience abrupt restrictions that ripple through crew-duty calculations, cargo schedules and passenger connections. Companies with frequent traffic to Lapland should review their contingency fuel policies and ensure that charter brokers monitor AIP supplements as closely as NOTAMs. In the longer term, Finland’s defence ministry says the experience will inform the design of permanent segregated drone corridors, a move that could provide clearer predictability for both military and civil users.
