Q2 2025 Airspace
Disruption Report
A quarter defined by bilateral airspace weaponization and the first coordinated international response to GPS interference. Pakistan closed its skies to Indian carriers, Baltic jamming reached unprecedented levels, and EASA and IATA jointly published a mitigation framework that acknowledged satellite navigation can no longer be taken for granted.

Airspace Closures
Pakistan-India Airspace Closure — April 24
On April 24, 2025, Pakistan closed its airspace to all Indian carriers following the April 2025 regional escalation — Indian military operations against targets in the disputed border area and Punjab. This bilateral closure created the most significant South Asian airspace disruption since the 2019 the 2019 regional crisis, but with far greater economic impact due to the growth of Indian aviation in the intervening years.
Pakistan CAA orders immediate closure of all Pakistani airspace to Indian-registered aircraft. Air India, IndiGo, Vistara, SpiceJet, and other carriers lose access to all Pakistan overflight corridors.
Air India reroutes all westbound flights via southern maritime corridor (Arabian Sea) or northern Afghanistan-Central Asia route. Average flight time increase: 90–180 minutes. Fuel costs surge.
Closure persists. Air India estimates $600M/year in additional operating costs. IndiGo suspends several Gulf routes as economically unviable without Pakistan overflight rights.
| Route Category | Impact | Rerouting |
|---|---|---|
| India → Europe | +90–180 min | Southern maritime or via Central Asia |
| India → Middle East | +45–90 min | Arabian Sea coastal routing |
| India → Central Asia | Suspended | No viable alternative for several routes |
| India → West Asia | +60–120 min | Southern corridor via Oman |
Finnair Tartu Route — Suspension Continues
Finnair's Helsinki–Tartu route remained suspended throughout Q2 2025, a direct consequence of persistent GPS jamming affecting the approach path to Tartu Airport. First suspended in 2024 due to interference from the Kaliningrad exclave, the route became a visible symbol of how ground-based electronic warfare can render civilian air routes commercially unviable — even in NATO airspace far from any active conflict zone.
Significance: The Finnair Tartu case demonstrated that GPS interference does not need to target aviation specifically to disrupt it. Broad-area military jamming from Kaliningrad — directed at military targets — created a permanent no-go zone for GPS-dependent instrument approaches at a civilian airport hundreds of kilometers away.
Russian Airport Closures — Accelerating
Drone-related closures at Russian airports continued to escalate in Q2 2025, with the geographic spread extending further from the original Caucasus hotspot. Southern airports remained the most frequently affected, but closures at airports in central Russia — including the Moscow region — began appearing with increasing regularity.
GPS Interference
Q2 2025 saw the Baltic region emerge as the most intensely monitored GPS interference zone in Europe, while the ongoing Middle East and Caucasus interference continued unabated. The quarter culminated with the first coordinated regulatory response — the EASA-IATA Joint GNSS Mitigation Plan.
Baltic Region — Unprecedented Escalation
22-fold year-over-year increase in GPS coordinate spoofing incidents. Lithuanian airspace became the single most affected national airspace in the Baltic region by Q2 2025.
At peak interference periods, 85% of civil flights in Estonian airspace experienced GPS signal degradation. Tallinn and Tartu approaches remain high-risk.
Finnair Tartu route suspended (since 2024). Eastern Finnish airspace experiencing increasing interference events from Kaliningrad-area sources.
Cumulative incidents since August 2023 exceeded 46,000 (Spire Global analysis). The rate of new incidents continued to accelerate through Q2 2025.
Middle East and Eastern Mediterranean
The Turkey–Iraq–Egypt corridor remained the global hotspot for GPS spoofing, with incidents concentrated along major air routes connecting Europe with the Gulf. Syrian and Israeli military operations continued to generate electronic warfare interference affecting civil aviation at cruising altitudes up to FL400.
Drone Incidents
Russian Airport Drone Disruptions
Drone operations against Russian aviation infrastructure continued through Q2 2025 with increasing frequency. Southern airports bore the brunt, but the geographic expansion toward central Russia — first seen in Q1 — continued.
Volgograd, Rostov-on-Don, Krasnodar, Mineralnye Vody — multiple closures per week. Some airports implementing pre-emptive nighttime restrictions.
Grozny and Makhachkala remain effectively closed to international traffic. Domestic operations intermittent. No recovery timeline visible.
Moscow-region airports beginning to experience closures. Pattern suggests geographic expansion northward will continue into H2 2025.
European Drone Sightings
European airports continued to report drone sightings near airfield boundaries, though Q2 2025 saw fewer major disruptions than the preceding winter months. Authorities in Germany, France, and the UK maintained elevated surveillance postures. Counter-drone investment continued to accelerate, with several airports deploying detection systems that had been procured in Q4 2024 and Q1 2025.
Financial Impact
Pakistan airspace closure forces rerouting of all westbound Air India flights. Additional fuel, crew time, and lost revenue from suspended routes.
Premium increases depend on carrier risk profile, fleet exposure, and route mix. Carriers with heavy Middle East/South Asia exposure see the steepest increases.
Rerouting around Pakistan adds 1.5–3 hours to each sector. At current fuel prices, this translates to $20,000–$60,000 per flight in additional operating costs.
IndiGo suspended several Gulf routes as economically unviable without Pakistan overflight rights. Revenue impact not publicly disclosed.
War risk insurance premiums entered a structural repricing cycle in Q2 2025. The combination of the AZAL 8243 precedent (GPS interference → hull loss), the Pakistan-India closure (bilateral weaponization of airspace), and continued Baltic jamming forced underwriters to fundamentally reassess how they price airspace disruption risk. Premiums are now route-specific rather than region-based, with GPS interference zones carrying additional loadings.
Regulatory Changes
EASA-IATA Joint GNSS Mitigation Plan — June 18
The landmark publication of Q2 2025: EASA and IATA jointly released a comprehensive GNSS interference mitigation framework on June 18. The plan covered four pillars:
Other Regulatory Actions
| Authority | Action | Date |
|---|---|---|
| Pakistan CAA | Airspace closure to Indian carriers | Apr 24 |
| EASA + IATA | Joint GNSS Interference Mitigation Plan | Jun 18 |
| EASA | Russia CZIB maintained and updated | Ongoing |
| NATO | Baltic jamming attribution statements (Kaliningrad) | May–Jun |
Q3 2025 Outlook
Bilateral tensions remain elevated. No diplomatic indicators suggest airspace reopening in Q3. Air India and IndiGo are adjusting fleet planning for extended rerouting.
Historical patterns show increased jamming activity during summer months (longer days, more military exercises). The 22x increase in Lithuanian incidents suggests Q3 could set new records.
The geographic expansion of drone-related closures northward from the Caucasus suggests Moscow-area airports will face their first significant disruptions in Q3 2025.
The EASA-IATA framework is comprehensive but implementation will take 12–24 months. In the interim, GPS interference risk remains unmitigated for most carriers.
