Anne has a point, however it can also work FOR you in that most pax, particularly in economy, are travelling at least in couples and often more. thus the last seats to be booked are likely to be those where there is only one seat available - ie, next to you. This means that if there are any empty seats on the a/c they are likely to be the ones you will benefit from most.
