What about a flight from Utqiagvik to Anchorage, connecting to an American flight through Dallas to the East Coast? Passenger has Emerald One World status, ticket purchased from AA. Would AS or AA baggage rules prevail given check-in at BRW? Alaska has already advised that they will not put anyone in the PNR record on the upgrade list for either premium or first class for the BRW to ANC leg because the ticket was purchased from American. So it seems if the 2 piece 50 lb. limit applies, AS is playing heads, we win, tails, you lose.
