It is from Galileo Deutschland. Go to
http://www.aeroplan.de/home.htm and click on GALILEO CRS.
You have to fill in at least 3 boxes, but not all, depending on what you need.
Abflughafen is origin.
Zielhafen is destination.
And you must fill in the date in European numerical order [1107 is July 11]. If you leave airline blank, you will see all airlines visible in Galileo [WN does not pay to be included and you won't see their flights, for example.]
If you UNCHECK THE BOX LABELED -Klartextanzeige - you will see the actual display the way agents see it.
The biggest weakness is that you cannot ask for further availabilities from the page that you pull up, i.e. flights later in the day or multisector itins. And you cannot specify time of day.
But you're going to like it a lot better. Perhaps others may find a better one and if so, I hope that they will share with us.
