Connections on Transfer Impossible Airports

Hello guys,

I have one doubt: How come some airports that are labelled as "transfer impossible" airports appear on the statistics page under the Airports Connections data?

Is it ground connection?

Cheers

No, but passengers can always "stay on the plane" and continue on the next flight on board the same plane.

Ohh of course.

So simple... Can't imagine how I missed that. Thanks!
