experimenting with various in/out dates and with/out stopover I find that the FF flight results vary widely. I understand that where a stopover is involved there would be a window before ongoing flights are shown, but this is beyond that kind of thing.
It's almost like I have to note that the criteria that yield a certain flight, and then carefully plan how to get that flight to show again.
