British Airways Executive Club: Double Avios on all BA flights out of Canada (and globally!)

The British Airways Executive Club Double Avios on all flights offer is
back! Launching a few weeks earlier than last year and also getting rid
of some the residence restrictions (which included Canada) this is now one of the best
systemwide global flight promotions on the market right now. I would say
this one falls in right after the Miles & More 25 miles per euro bonus but ahead of the current Air Canada systemwide bonuses.

BA serves Montreal, Toronto and Vancouver regularly and is serving Calgary until late October.
