In the event of a disruption on the originating ticket, the carrier responsible for the disruption will be required to reroute the customer to their final destination."

In the example provided by the op, both segments are on AC metal (I assume). Assuming segment #1 has a delay, wouldn't AC have an obligation to assist in this case? We're not even talking about another *A airline...

Secondly, has anyone found a verbatim quote protecting a passenger flying *A, as above?

Note: I'm aware there could be delays with visa/border control, but I'm referring to delays or mechanicals with the originating operator.
