Looks like all YYZ flights to LGA and EWR cancelled as of 10am today and all day tomorrow. BOS cancelled as of tonight and all day tomorrow. PHL cancelled all day today, up to late tomorrow aft.
Some US airlines still haven't cancelled yet.
well AC certainly screwed the customer today. LGA and EWR are still fine, and AC stopped its flights at 10AM?
What news did AC watch that they screwed up so badly?
