I am missing a couple of rental car transactions in my account from a couple of months ago. The aeroplan website says that I should send the receipts to a PO box in Vancouver, while the recording at the aeroplan phone number says I should send it to a PO box in Dorval.

Which (if not both) is the correct address, and if both, does it make a difference which one I send it to? Will one process it faster than the other?
