Could you be looking at the “Actual Availability” in the first screen and on “Authorized Available” on the second? Authorized is what is available for sale with includes overbooking seat. So 5 are actual free seats unsold, but they are still authorized to sell 13 (which would mean that they will overbook by 8 seats (13-5=8). Find a flight that is doing this and post here and I will look at what you are talking about. (skicat 2005/08/05 05:14)
