Middle East Airspace Closures: Operational Impact on Business Aviation and GA Flights

Current Airspace Status Snapshot

The operational picture across the Middle East remains highly fluid, with multiple FIR closures and restrictions continuously extended via NOTAM.

All restrictions outlined below are subject to continuous NOTAM extension and should be treated as ongoing.

Rather than isolated disruptions, the region is now operating under a sustained airspace compression environment affecting Europe–Asia traffic flows.

Closed FIRs (No Transit Available)

The following FIRs are currently not available for normal civil overflight and should be treated as closed for planning purposes:

• Tehran FIR (OIIX) – Closed to civil traffic except state, military, SAR, and flights operating with prior permission
• Baghdad FIR (ORBB) – Closed to civil traffic
• Kuwait FIR (OKAC) – Closed to civil traffic
• Bahrain FIR (OBBB) – Closed except for limited, pre-approved departures from Bahrain International Airport (OBBI) via designated exit routing
• Doha FIR (OTDF) – Overflights restricted; arrivals and departures permitted only via designated routing with prior approval

These restrictions are being extended on a rolling basis and should be considered ongoing.

Closed with Limited Operational Exceptions

Some FIRs remain technically accessible but only under tightly controlled conditions:

• Tel Aviv FIR (LLLL) – Civil arrivals and departures permitted only with prior approval; military flights require Israeli Air Force authorization
• Damascus FIR (OSTT) – Closed except for highly restricted operations:
  • Aleppo arrivals/departures via B544 TUSYR, M861 NISAP, W6 BANIAS NIKAS
  • Limited overflight routing via NIKAS–BAN–W6–ALP–TUSYR–B544
  • Latakia (LTK) via BAN–SALIM–TUNLA
  • Military flights authorized

These FIRs should not be considered viable for flexible routing.

Open but Structurally Restricted FIRs

These FIRs remain open but are operating under constraints that materially impact routing flexibility:

• Emirates FIR (OMAE)
  • Access limited to designated waypoint corridors
  • Westbound overflights restricted to LUDID
  • Flow management measures and sequencing delays expected
• Jordan FIR (OJAC)
  • Open with congestion-driven delays
  • Additional fuel recommended due to potential holding and reroutes
• Saudi Arabia FIR (OEJD)
  • Open but absorbing displaced regional traffic
  • Operators advised to carry contingency fuel due to delays or diversion risk
• Oman FIR
  • Open and functioning as a primary routing corridor
  • Subject to dynamic flow measures, reroutes, and rapid NOTAM updates

Routing Restrictions (Caucasus Corridor)

Baku FIR (UBBA) continues to impose waypoint restrictions that reduce flexibility for northern Europe–Asia routings:

Unavailable waypoints:

• ULDUS
• BATEV
• LALDA
• PARSU

Recommended routing adjustments:

• To/from Yerevan FIR: MATAL, ELSIV, PEMAN
• To/from Turkmenbashi FIR: MARAL, METKA, RODAR, LARGI

These restrictions remain in effect under continuously extended NOTAMs.

What This Means for Operators

The central Gulf and Levant airspace structure is no longer usable for standard Europe–Asia transit.

Operators should plan on:

• Southern routings via Egypt, Saudi Arabia, and Oman
• Northern routings via Turkey and the Caucasus with reduced flexibility
• Increased congestion and ATC flow management in all remaining corridors

Routing availability should be treated as dynamic, with limited predictability even within short planning windows.

Closed and Restricted FIRs Across the Central Gulf and Levant

With Tehran, Baghdad, Doha, Kuwait, Bahrain, and Damascus FIR effectively closed or heavily restricted, there is no direct through routing across the northern and central Gulf.

The Tel Aviv FIR (LLLL) also remains restricted, with civil arrivals and departures operating only with prior permission and military flights requiring Israeli Air Force approval.

The Emirates FIR (OMAE) remains partially open but is operating under tightly controlled waypoint corridors, active restricted areas, and flow management measures. Westbound overflights are currently limited to entry via waypoint LUDID.

Regional airspace capacity remains materially reduced, and operators should plan accordingly.

Routing Implications: Europe–Asia Traffic Is Reorganizing

With the central Gulf corridor largely unavailable, Europe–Asia traffic flows are reorganizing along two primary alternatives.

Southern routings are operating via Egypt, Saudi Arabia, and Oman before turning east toward the Indian Ocean and South Asia. This corridor is absorbing a significant portion of displaced traffic from the closed Gulf FIRs.

Northern routings are shifting through Turkey and the Caucasus before continuing toward Central or South Asia, though routing flexibility may be reduced by waypoint restrictions within the Baku FIR.

Both alternatives are experiencing elevated demand, increased ATC flow management, and reduced routing flexibility. As a result, dispatch teams should anticipate longer routings, higher fuel burn, and increased likelihood of tactical reroutes during both planning and enroute phases.

Operators should assume continued volatility as NOTAM updates and traffic demand evolve across the region.

UAE Is Open but Structurally Constrained

Relevant NOTAM:

OMAE A1148/26 – Emirates FIR partially closed: Arrivals and departures are restricted to designated waypoint corridors, overflights are limited to westbound transit via LUDID, and flow management measures may be implemented.

Operational implications:

• Traffic compressed into defined entry and exit fixes
• Tactical ATC reroutes likely
• Holding probability increased
• Congestion into OMDB, OMDW, OMAA, OMSJ, and OMRK

The Emirates FIR remains accessible only through designated waypoint corridors defined by the current NOTAM structure. Designated restricted areas are active, traffic sequencing measures are in force, and reports of satellite navigation interference add further operational considerations.

While UAE airports remain technically open under these constraints, commercial schedules continue to face disruption, with cancellations and relief operations replacing normal service patterns.

Jordan Airspace Status

Jordanian airspace remains open but operators should anticipate possible inbound delays due to regional traffic displacement.

Aircraft operating into Jordanian airports are advised to carry additional fuel to accommodate potential holding, sequencing delays, or tactical reroutes implemented by ATC.

Saudi Arabian Airspace Status

Saudi Arabian airspace remains open but authorities advise operators to carry sufficient contingency fuel due to potential delays or diversions caused by increased traffic volumes and regional routing changes.

Oman Is the Pressure Valve

Oman remains open but is managing dynamic airway closures and flow measures to absorb diverted traffic.

While no blanket FIR closure exists, operators should expect:

• Tactical reroutes
• Airborne sequencing
• Flow management initiatives
• Rapid NOTAM updates

Oman is currently the primary stabilizing corridor, increasing its strategic importance.

System-Level Impacts

With multiple FIRs closed and others restricted, regional airspace capacity is materially reduced.

Immediate operational risks include:

• Extended routing and increased fuel burn
• Reduced alternates flexibility
• Permit amendments due to rerouting
• Crew duty limitations on ultra long sectors
• Slot compression at Gulf hubs
• Increased probability of short-notice NOTAM updates

In compressed airspace environments, small planning assumptions create outsized operational risk.

Dispatch Reality: Route Planning Is Now Dynamic

For dispatch and trip planning teams, routing assumptions that were reliable even a few weeks ago may no longer apply. Many traditional Europe–Asia routings are no longer available, and the remaining corridors are subject to rapid NOTAM updates and tactical ATC flow measures.

Operators should expect routing revisions during the planning phase and potentially again prior to departure. Conservative fuel planning, flexible overflight permit coverage, and close coordination with handlers and flight planning providers are increasingly important in the current environment.

This is not simply a longer route planning exercise. It is an environment where routing availability can change within hours.

Secondary Effects: Europe Is Now Feeling It

The impact is no longer confined to the Gulf. European airports are now absorbing operational spillover as operators reposition aircraft and reroute long haul sectors.

Greece: Diversions and Parking Saturation

Greece has been directly affected by Middle East airspace restrictions, particularly Athens LGAV.

“We’ve definitely been affected by the tension in the Middle East,” says Dimitra Kiriakopoulou, Universal Aviation Greece. “We’ve had multiple diversions into Athens. Scheduled flights to and from the region have been cancelled, and we’re seeing increased demand for long term parking from aircraft repositioning out of the Middle East, not only in Athens but across other locations in Greece as well.”

The weekend saw significant ad hoc traffic, tightening parking availability quickly.

“Things are somewhat smoother now compared to the weekend,” Kiriakopoulou adds, “but overall traffic remains elevated, parking availability is very limited, and any escalation in the situation could impact us again.”

Greece is effectively functioning as a staging and overflow location for operators repositioning aircraft out of constrained Gulf airspace.

United Kingdom: Long Haul Rerouting and Evacuation Movements

In the United Kingdom, operators are navigating around closed and restricted FIRs with non traditional routings.

“We’re seeing operators finding a way and navigating around the airspace closures,” says Sean Raftery, Universal Aviation UK. “For example, we had an FI team routing Milan to Stansted to Hong Kong to Melbourne because they could not route via Dubai. We’re also seeing flights moving people out of certain areas.”

These reroutes are increasing mission complexity, fuel planning requirements, and crew duty considerations, particularly on long haul sectors traditionally routed through the Gulf.

Turkey: Increasing Requests for Parking and Diversions

Turkey is also seeing increased operational interest as operators evaluate alternative staging points and reposition aircraft out of the Middle East.

Local handlers report growing inquiries tied to aircraft repositioning and longer-term parking requests. According to guidance from the Turkish Civil Aviation Authority, permits are now required for long-term parking approvals, and operators should coordinate requests early as airport authorities review availability.

While Turkey remains fully operational from an airspace standpoint, the combination of rerouted Europe–Asia traffic and repositioning aircraft may tighten parking availability at key airports if the situation persists.

Operator Guidance

• Validate routes immediately prior to dispatch
• Add contingency fuel beyond standard planning margins
• Confirm overflight permit flexibility for rerouted paths
• Identify alternates outside restricted FIRs
• Monitor NOTAM updates continuously
• Build schedule buffer into ETDs
