Ranks first on airspace: the only Hong Kong to Madrid option with no advisory zone contact on either leg. Complexity score reflects the two-stop geometry and total journey time (~16 hours), but the airspace cleanliness is the primary differentiator.
Hong Kong to London first leg uses Cathay Pacific's Central Asian corridor routing — no active advisory zone contact post-2022 rerouting.
London to Madrid second leg is a clean short-haul sector via British Airways or Iberia — no advisory zone involvement.
The London hub break adds complexity: total journey is approximately 16 hours including transit. Worth it if avoiding advisory exposure is the priority.
London is the strongest European hub for Hong Kong-originating traffic — deep Cathay and British Airways frequency.
Best choice when minimising airspace risk is more important than minimising journey time.
