Althout my status changed to SE on aeroplan a day ago, air canada reservations (as was discussed earlier) didn't have it in their system and couldn't update it. This was important as I just moments ago entered the 7 day window to confirm an upgrade LHR-YVR and there is only one I inventory available. So, after the agent told me I would have to wait until 4 days before I could request an upgrade due to the fact I appear as Elite in their system, I asked if he could manually check with aeroplan re: my status. He seemed doubtful but after a minute on hold he had confirmed that my status had changed to SE and was able to confirm the upgrade. Needless to say I am pleased with how this all worked out! And although I have never had a problem getting upgrades as Elite (even from SYD recently) it has often come down to the wire, so I look forward to taking the SE status for a spin and seeing if it makes a difference (I am a newbie).
