- Flight-route display is now a setting — with an honest reliability note.
Configuration → Display gains a "Flight routes" toggle controlling the
origin → destination lines on the radar overlay, the aircraft detail page,
and the display board. The setting's description says plainly what the
routes are: community-maintained schedule data from adsb.lol, matched by
callsign. That's usually right, but not guaranteed — the same callsign can
fly different routes on the same day, so the displayed route (especially
the origin) may occasionally disagree with the flight actually overhead.
If that trade isn't for you, switch it off: route lines disappear from
every surface and Aerodrome stops making route lookups entirely. On by
default; applies the next time a page loads.
