How to Check if an Airspace Is Closed
Last updated: April 2026
Airspace closures happen for various reasons: armed conflict, military exercises, volcanic activity, or space launches. When airspace closes, airlines reroute flights around the affected area, which can add flight time and fuel costs. This guide shows you how to check the current status of any airspace using publicly available tools and official sources.
Check the ICAO NOTAM portal
Search the ICAO NOTAM database or your national AIS for the FIR (Flight Information Region) or airport code in question. Airspace closures are published as NOTAMs with specific Q-codes indicating restricted (RA) or prohibited (PA) areas. Filter by the relevant FIR to see all active restrictions. See our NOTAM reading guide for details on interpreting what you find.
Review EASA CZIBs for conflict zones
Visit the EASA Safety Publications Tool and check active Conflict Zone Information Bulletins. CZIBs cover regions where armed conflict poses a risk to civil aviation, as assessed by EASA. Each bulletin indicates the restriction level (recommendation to avoid, strong recommendation, or instruction not to operate), the affected FIRs, and any altitude limitations. See our CZIB guide for detailed interpretation.
Check FAA SFARs for US restrictions
Search the FAA website for active Special Federal Aviation Regulations (SFARs). SFARs carry regulatory force and prohibit US-registered aircraft and US operators from entering specified airspace. The FAA also issues NOTAMs for Temporary Flight Restrictions (TFRs) covering shorter-duration events. See our SFAR reading guide for details.
Use Safe Airspace or OpsGroup maps
Third-party services like Safe Airspace (safeairspace.net) and OpsGroup compile restriction data from multiple official sources into visual maps. These tools aggregate NOTAMs, CZIBs, SFARs, and national restrictions into a single overview showing which airspaces are restricted and at what level, according to their published data. They are useful for getting a quick visual picture, though official sources remain the authoritative reference.
Check airline communications
Your airline monitors airspace status as part of its flight operations and dispatch process. Check the airline app, your booking confirmation page, or email for notifications about route changes, increased flight times, cancellations, or schedule modifications. These changes may indicate that airspace along your original route has been closed or restricted.
Review your government's travel advisory
Many governments publish aviation-specific warnings within their travel advisories. Check your foreign ministry or state department website for warnings about flying through or over specific regions. Some governments (e.g., UK, France, Germany, Canada) issue explicit aviation advisories that supplement the EASA and ICAO notices.
