I'll go first... (I did try searching to find the answer to this question)
Here is my situation, any advice/info would be greatly appreciated!
I am a Diamond with Delta. I have Alaska miles. I want to book an Alaska award ticket which has a mixture of Delta and Alaska flights. I want to receive Delta benefits on the Delta flights (baggage, economy comfort, SkyPriority boarding, etc)
When I log into my Alaska account and try to book the ticket it automatically puts my Alaska FF# in. I tried booking for another traveler and it leaves the FF# blank, but only Alaska is listed under program with no option to change.
Is it possible to book the award ticket using my Alaska Miles and then put in my Delta SkyMiles number so I get my Diamond benefits on the Delta flights?
