Via Hong Kong
Flowing · 79
Clear airspace · Weak reroute options · Moderate extra time

Clean airspace on both legs. SYD–HKG is a high-quality regional sector; HKG–LHR uses Central Asian routing. Best choice if you want both segments completely clear of the Middle East zone.

The catch

Very few backup paths if this route is disrupted

Via Dubai
Limited · 55
Through a warning area · Moderate reroute options · Moderate extra time

The top option avoids the warning area this route crosses.

Highest name-recognition option on this corridor. Strong Emirates frequency and a premium hub experience, but the DXB–LHR second leg transits the active Middle East advisory zone.

The catch

Part of this route goes through a flight warning area

How we score routes

We score each route based on whether it flies near or through warning areas, how much longer it is, and how many reroute options exist — based on official flight warnings.

Some routes aren't covered yet — if yours is missing, that's a gap, not an assessment.

Scores compare route options; they are not safety ratings. Always check with your airline before booking.
