I have found that if you confirm your flight exactly at the 24 hour point allowed you can get a B number usually in the 31-60 group. It also depends on how fully booked the flight is and the airport you are leaving from of course. Since we prefer to sit in the rear of the plane it has never been a problem to find 2 seats together and sometimes have an empty seat between us. Except once when we stayed in the airport bar too long <img src="http://www.traveltalkonline.com/forums/images/graemlins/dine.gif" alt="" /> <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" />.
