The way things are going at AC, there will most likely be sched and/or equipment changes before flight. To ensure you have a confirmed seat, make sure row number is less than 9, the last row on a Dash 8.
A colleague of mine had a trip last week with 5 segments. Four segments with equipment changes lead to mass confusion, double seat assignments and pax left behind since there were not enough seats to go around.
