is there a problem with Availability-FS? I can not return itineraries with more than one connection for my intended trip. e.g. was looking at this query: PIT-VIE Aug 27, all airlines, sort by connections, filters unchecked. Only 1-stop trips returned. I know there is a PIT-YYZ-FRA-VIE, for example, that isn't there.

And its inconsistent - PIT-PSA shows lots of 2 stop trips. PIT-FRA only 1 stop..

Ideas?
