Houthi attacks on aviation and shipping have forced Europe–Asia flights off established Red Sea and Gulf corridors and onto longer routings through Central Asia, raising fuel burn, crew hours and exposure to unfamiliar overflight environments, Chosunbiz reports.

The shift removes some of the most direct great-circle paths between European hubs and South and Southeast Asia. Carriers that once crossed the Arabian Peninsula and the Red Sea region now plot tracks farther north, over countries such as Turkmenistan, Uzbekistan, Kazakhstan and neighboring Central Asian states, adding distance to sectors that were already among the longest in global networks.

What does the rerouting change?

The immediate consequences are operational and financial. Longer flight times mean:

• Higher fuel consumption per Europe–Asia rotation
• Additional crew duty time, pressuring scheduling on ultra-long sectors
• Reduced payload or technical-stop requirements on the longest city pairs
• Higher overflight and navigation charges across a wider set of states

Chosunbiz characterizes the new paths as both risky and costly, noting that airlines must now manage overflight approvals, contingency planning and diversion options across Central Asian airspace that was previously a secondary corridor for Europe–Asia traffic.

Why is airspace still closed?

The trigger is the persistent Houthi campaign of strikes, which has made airspace over the affected region unreliable for civil operations. Regulators and operators have kept avoidance measures in place rather than accept the risk of operating through a zone where attacks have occurred, and no near-term reopening is implied by the report.

That keeps the cost pressure structural rather than temporary. Every additional hour in the air on a rerouted Europe–Asia service compounds across daily rotations and full schedules, and the burden falls hardest on the longest sectors where payload-range margins are thinnest.

What comes next?

Until the security situation over the Red Sea region changes, carriers serving Europe–Asia markets will continue to absorb the cost and complexity of Central Asia routings, and network planners will factor that penalty into capacity decisions on the affected city pairs.
