Site for verifying the flight plan between two airports

Hi all, there was a website avaiable where you see the planned routes between to airports, which airline is operating it and with which aircraft

This was shown for the next months and not only days.
Unfortunately i did not bookmark the site.

Does anyone know about that site?
Sites like flightconnections.com are giving the details, but not e.g. in 3 or four months.

It was a simple site showing the connections in a simple table.
