Thanks to Anne R and Cheryl G at YYZ for saving our bacon today and helping us make our cnx to AC868 coming off of AC8909 which was delayed 90minutes exYQB because of massive fog.
My travel companion, who is E, was very impressed..."I just got an email from AC saying we were rebooked on an evening flight to LHR"....I told him to never mind that nonsense and trust in the concierges.
It worked out and we made it for pints in London before closing time.
