I just checked it too, and it says - when you roll the mouse over availability - "9(at least)". So that means to me that there are at least 9 seats to sell...now...working for an airline that doesn't let it's own employees know the exact bookings (even through our employee portal) that doesn't mean much...HOWEVER, if you look a little closer, you'll notice the different fare types in the cabin (ie: Y9/J9/F9/C9/G0/F4 etc.). It's a pretty good indication when all the letters have the same number: 9/7/4 (each airline has a different policy in the number of seats they show per booking class) that the flight has plenty of availability. hope that helps!
