I am looking at booking ORD-SFO-YVR/YVR-SEA-ORD shortly. All segments except YVR-SEA (AC) on the return are UA metal. Does most significant carrier rule apply on the AC segment, allowing all 4 passengers on the itinerary the usual UA Gold checked baggage allowance?...
MSC is not used or flights originating or returning to USA, instead the DOT rule is used. In that base, the ticket benefits of the marketing carrier of the first segment are used.
Note the phrase is "ticket benefits". This is the benefit without elite benefits. The check-in carrier can apply elite benefits in addition but it is not binding on the other carriers.
So at the UA checkin you will get the ticket bag allowance / UA Gold benefit (2 bags @ 70 lbs)
Went you check in with AC, you will get the ticket allowance plus 1 additional bag (at the same weight) (The *G benefit)
