Crossed 3MM as AC 852 approached LHR yesterday.
YYT Concierge had a small celebration before my departing flight, in-charge mentioned just before landing in YYZ. Concierge waiting for me in YYZ with Porsche service. In-charge gave me a bottle of Champagne just before landing in LHR.
Amazing! Good for you...or something like that. Seems like a very small club!
