Priority call wait times are about the only significant benefit of Aeroplan diamond status. Kind of sad when one has to achieve that in order to receive the basic service they should be able to offer to everyone. I can't imagine telling my clients that we're only going to answer the phone if you're one of our best clients.
The automatic hang-up after a recorded message when all lines are full is really annoying, but a couple of quick redials normally gets into the queue. I've never had to wait more than about 2 minutes for an agent once in the queue.
