Via Hong Kong

Best
Flowing 72
Near zone airspace · ~11h 50m · Some options

Second viable option via Cathay's Hong Kong hub. ICN–HKG is clean; HKG–LHR uses the Central Asian corridor. Best rebooking depth of the non-Gulf options.

Weakness

Route passes near an advisory zone (not through it)

Watch

HKG–LHR uses the Central Asian corridor for its westbound routing. Check Cathay NOTAM status for the LHR segment if Central Asian flow restrictions are active.

Watchful 63
Near zone airspace · ~11h · Few options

Most direct option on this corridor. Korean Air's ICN–LHR service routes via the Central Asian corridor — one level-1 advisory segment, but no Gulf exposure.

Via Dubai

Advisory airspace · ~13h 10m · Some options

High-frequency option via Emirates. ICN→DXB is clean; DXB→LHR crosses the active Middle East advisory zone on the second leg.

How this is assessed

FlightDetour evaluates route options using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on publicly available EASA and national authority advisories.

Coverage focuses on major long-haul corridors. Some routing patterns — including certain China-side connections via mainland Chinese hubs — are not yet included. If you expect an option here and don't see it, that's a coverage gap, not an assessment.

Scores compare corridor quality; they do not predict airline operations or safety outcomes. Verify with your airline and government travel advisories before booking.
