That's a bit funny then - Maybe they are pulling out then. Obviously their YYZ-MAN service has been switched to bmi, so maybe they're ditching all their UK regional service and focussing on LHR
As I mentioned they do have extra competition to YYZ itself, and I guess the new GLA-PHL and EDI-EWR services starting this summer might mean more competition for connecting traffic to the US and Canada.
I know a few people who are booked to use that service to connect on to US destinations this summer - they only picked AC over CO/US/AA cause it was cheapest - they'll be mad if they have to go via LHR
If an airline cancels a route do they only offer rerouting on thier own flights, or do they offer a refund as well?
