I would be interested to know if anyone has received a satisfactory explanation as to how one is supposed to effectively use eupgrades for travel in the first week or ten days of March on popular routes. I understand from Aeroplan that they have been pushing AC to allow members to select privledges in mid-Feb so that we can upgrade March flights now. Apparently AC has been very unresponsive. I have 2 long-haul flights in the first 2 weeks of March - upgrades to Latitude fares for these flights are the essence of why many of us support Aeroplan. Logically there should be a solution to this.
