My reservation would be for Delta flight #9*** which is not listed as an eligible flight for earning partner miles. Does the fact that the actual plane itself is an Alaska Airlines flight being codeshared by Delta, change that at all. Would you say that flight will definitely not earn Alaska miles...or should I check with customer service? Thanks.
