Korean Air Direct
Limited · 52
Near a warning area · None reroute options · Moderate extra time

Most direct routing when the Central Asian corridor is clear. No connection risk, but entirely dependent on one corridor — high schedule variance.

The catch

Only one path. No other way if it closes

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.
