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

Cleanest airspace on both legs if Gulf avoidance is the priority. LHR–HKG via Central Asia; HKG–SYD clean southerly routing. Longest option but zero Gulf involvement.

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.

High name recognition and strong hub frequency, but the LHR–DXB first leg transits the active Middle East advisory zone. Book with awareness of current conditions.

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.
