Clear airspace · Moderate reroute options · Moderate extra time

Clean alternative via HKG. Both legs avoids the warning area entirely. Cathay Pacific's HKG hub is well-placed on the BKK–NRT geometry and adds less time than the SIN routing.

Clean alternative via SIN for when direct fares are high or schedules don't align. Singapore Airlines' SIN–NRT segment is one of the most reliable in the region.

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.
