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.
