Be careful. A number of people book flights and don't book a seat. Not sure why, but they do it all the time. Our flight looked half empty about 3 months out, but it was 90% full when I called to make a change to our flight from Peoria to Atlanta.
Thanks for the warning. I hadn't thought of that. I'm planning to book in Jan, so the trip will still be 6 months out, so I'm hoping there won't be a problem. I'm more afraid that, with the economy the way it is, the trip will be cancelled.
