As we know, airlines do not normally offer any kind of compensation for weather-related delays. Does AC have a similar policy as UA for their SE and E?[/QUOTE]

As others have noted UA1K. UACS notes it as Mechnical and not weather.
UA considers Canada International.
The benefit is only for UA1K. No *A Elite,including AC SE.
UA does not even give E+ or Red Carpet boarding to AC SE.
One can say enough complains to UA about unfairness of AC E & SE getting UA UGS&1K benefits is paying off. UA is listening to its UGS & 1K.
AC Elites & SE only get the benefits which are outline in the *A agreement,which is how it should be.
AC does not give UA1k or PE any additional benefits that AC E & SE get, so I do understand why AC E & SE expect UA should extend UGS&1K benefits to them.
