What are the rules surrounding the MLL One-Time Guest Passes from the 25K Select Benefit? The wiki says that for all cases, you also need a "same day departing boarding pass (for a flight operated by AC or another *A member", but the AC website for Guest Passes says it needs to be AC-operated ("same-day, confirmed ticket on a flight operated by Air Canada, Air Canada Rouge or under the Air Canada Express brand").

Will holding a same-day departing BP operated by a *A member (e.g,, United) suffice for MLL One-Time Guest Passes?
