The Middle East routing environment remains structurally constrained despite several FIRs remaining technically open.

The operational issue is no longer broad airspace closures alone. The challenge is the growing complexity created by approval-based access, fixed routing structures, compressed traffic flows, tactical ATC handling, and rapidly changing NOTAM conditions.

Several Gulf FIRs that were previously operating normally are now functioning under partial closure procedures, mandatory routing structures, tactical ATC handling, or prior approval requirements. The result continues to be compressed Europe-Asia traffic flows through fewer usable corridors and reduced operational flexibility across the region.

“Open” airspace still does not mean normal operations.

What Changed Since the Initial Closures

Recent NOTAM extensions and revisions confirm that multiple Gulf FIRs remain operationally restricted longer than originally anticipated.

The operational challenge is no longer broad regional closure alone. The issue is the growing complexity created by partial reopenings, mandatory routing structures, compressed traffic flows, approval-based access, and rapidly changing NOTAM conditions.

Several FIRs that were previously operating under emergency restrictions are now functioning inside tightly managed routing structures with tactical ATC handling, limited reroute flexibility, and dependency on adjacent FIR availability.

Current operational changes include:

• Syria issued new temporary route deconfliction procedures across Damascus FIR, including directional routing restrictions and altitude allocations tied to tactical ATC approval.
• Bahrain FIR restrictions remain in place with all flights subject to prior approval and tightly defined routing structures.
• Qatar FIR continues operating under partial closure procedures with fixed arrival, departure, and overflight corridors.
• UAE FIR remains partially closed, with overflight and arrival routing restricted to specific waypoints, airway structures, and temporary routing limitations.
• Kuwait FIR continues requiring prior approval for all flights transiting or landing within Kuwait FIR.
• Iran continues operating under significant restrictions, including western Tehran FIR airport closures, daytime-only airport operations in some locations, and limitations on general aviation and VFR activity.

The routing system remains operational, but highly managed.

Current FIR Status Overview

Syria (OSTT)

Damascus FIR remains operational under temporary route deconfliction procedures.

Recent NOTAM updates established temporary east-west routing structures, directional airway restrictions, and altitude allocations coordinated directly with Damascus ACC. Tactical ATC approval remains a significant operational factor.

Operators should expect:

• Restricted routing flexibility
• Tactical ATC coordination requirements
• Altitude assignment limitations
• Potential reroutes tied to adjacent FIR coordination
• Increased operational complexity for overflight planning

The operational issue is not simply whether Syria is technically available. The challenge is that traffic is now operating inside tightly controlled procedural structures.

Bahrain (OBBB)

Bahrain FIR remains operational but heavily proceduralized.

All overflights, arrivals, and departures require prior approval from Bahrain Civil Aviation Affairs. Routing flexibility remains limited to published corridors and defined entry and exit structures.

Operators should continue expecting:

• Restricted routing flexibility
• Tactical ATC flow measures
• Congestion-driven reroutes
• Dependence on adjacent FIR availability

This is not unrestricted Gulf routing.

Qatar (OTDF)

Qatar FIR remains under partial closure procedures.

Arrival, departure, and overflight traffic continue operating only through defined routing segments and waypoint structures including GEXIM, ORMID, OBROS, KINID, OVONA, LAEEB, and ORLEK.

Operators should continue planning for:

• Limited reroute flexibility
• Tactical sequencing
• Flow restrictions
• Routing dependency on neighboring FIR availability
• Temporary airway closures tied to special activity NOTAMs

The operational issue is no longer whether Doha FIR is technically open. The issue is that routing options remain compressed and highly structured.

UAE (OMAE)

The Emirates FIR remains partially closed under structured traffic management procedures.

Both arrival and overflight traffic continue operating through approved routing structures with mandatory waypoint sequencing.

Dubai-area airports remain accessible, but under compressed routing conditions that reduce operational flexibility and increase congestion risk.

Operators should continue planning for:

• Tactical reroutes
• Flow management measures
• Longer routings
• Reduced recovery flexibility during disruptions
• Increased dependency on adjacent FIR conditions
• Temporary airway suspensions and directional routing limitations

Kuwait (OKAC)

Kuwait FIR remains operational under prior approval procedures.

All scheduled and non-scheduled flights transiting or landing within Kuwait FIR continue requiring advance authorization from Kuwaiti authorities regardless of flight type.

Previous approvals should not be treated as valid for current operations. Operators cannot rely on historical permissions or previously accepted routings.

Flights entering the FIR without updated approval remain subject to:

• Delay
• Refusal of entry
• Tactical ATC rerouting
• Diversion risk

Iran (OIIX)

Iranian airspace restrictions remain significant despite partial reopening measures.

The eastern portion of Tehran FIR continues supporting limited overflight activity under operational conditions including ACAS requirements, mandatory ACC coordination, retained SSR codes, and larger ATC separation standards.

Western portions of Tehran FIR remain restricted, with multiple airports closed or operating only during daylight hours.

Operators should not interpret partial overflight availability as a return to normal Middle East routing conditions.

Oman (OOMM)

Oman remains operational and continues supporting multiple contingency routing structures.

Temporary bidirectional routing segments and contingency airway structures remain active as regional traffic compression continues affecting Gulf traffic flows.

Operators should continue monitoring routing validity closely as adjacent FIR restrictions continue impacting onward route availability.

The Operational Reality: Compression, Not Closure

The largest operational challenge is no longer whether airspace is technically open.

The issue is that too much traffic is now attempting to move through too few viable routing options.

This continues creating:

• ATC flow restrictions
• Tactical reroutes
• Departure sequencing delays
• Increased fuel burn
• Reduced alternate flexibility
• Higher disruption risk during weather or recovery events

Even partially reopened FIRs continue operating under conditions that materially reduce routing efficiency.

Most Common Operator Mistakes

Operators continue running into problems by:

• Assuming a partially reopened FIR restores normal routing capability
• Filing historical routings without validating current airway availability
• Underestimating congestion across southern Gulf corridors
• Carrying insufficient contingency fuel for reroutes or holding
• Treating approvals as static rather than operationally dynamic
• Assuming previously approved routings remain valid after NOTAM revisions

What Causes Missions to Fail or Delay

Most current disruptions are now being caused by secondary operational effects rather than direct closures.

Typical failure points include:

• Last-minute routing amendments
• Permit revisions tied to routing changes
• Flow management delays in compressed corridors
• Insufficient fuel margins
• Loss of alternate flexibility
• Adjacent FIR restrictions impacting otherwise valid routings

Small planning assumptions continue creating disproportionate operational impact.

Expert Perspective

“Operators still see the word ‘open’ and assume operational flexibility has returned. In reality, most of these FIRs are functioning inside tightly managed routing structures with approvals, procedural constraints, or reduced ATC flexibility. The airspace may technically be available, but the operating environment is still highly compressed,” says Greg Murray, Master Flight Planner, Universal Weather and Aviation.

Operator Guidance

Operators should continue planning conservatively across the Middle East region.

Recommended practices include:

• Validate routings immediately prior to departure
• Carry additional contingency fuel beyond normal planning margins
• Prepare multiple routing scenarios in advance
• Maintain flexibility on permits and schedules
• Identify alternates outside restricted FIR structures
• Continuously monitor NOTAM updates across adjacent FIRs
• Build schedule buffer into ETDs and onward mission planning

Bottom Line

The Middle East airspace environment remains operationally constrained despite partial reopenings.

The routing system is functioning, but under structured and capacity-limited conditions that continue compressing traffic flows across the region.

Operators that plan conservatively and maintain routing flexibility continue operating successfully. Those relying on historical assumptions or static routings remain exposed to disruption.
