Why book

Avoids Gulf and Middle East completely. Best choice if you want to keep both legs away from the active advisory zone, but total journey is longer.

The catch

Very few backup paths if this route is disrupted

Worth knowing

LHR–HKG uses the Central Asian corridor. If Eurocontrol flow restrictions are in effect on departure day, the first leg is vulnerable to delays.

Same clean airspace as Istanbul — neither leg touches the advisory zone. Ranked lower because the LHR–HKG first leg runs through the most congested section of the Central Asian corridor, which adds schedule risk.

Neither leg touches the Middle East advisory zone: LHR→HKG goes east via Central Asia, HKG→BKK goes south via South China Sea — a completely Gulf-free routing.
Hong Kong (HKG) is one of the world's most resilient hubs. Cathay Pacific has maintained full LHR service throughout the post-2022 disruption period.
The LHR–HKG leg relies on the Central Asian corridor — the same structural bottleneck as Istanbul routing, but occurring on the first leg rather than the second.
Total journey is approximately 80 minutes longer than the Istanbul option due to the more easterly routing geometry.
This corridor makes most sense if Gulf escalation drives you to avoid Middle East airspace on both segments, not just one.
