It's hard to fathom but Aeroplan (AC) had a 7-day function for future availability both for Departures and Return on their Trial Enhanced Booking engine last week for a few days that was really good but then mysteriously it disappeared over the weekend and it's back to searching day-by-day. If it's reintroduced it'll be on FT Air Canada as soon as someone discovers it. It was very, very good and one of the few good things they've done recently.
