OK, let's see if I have this right. I have an Alaska Airlines Mileage Plan and a Hawaiian Airlines mileage plan. I now have a Delta Sky Miles number also.

Last September I booked a January 17, 2011 flight on Delta, before I had the Delta Sky Miles number and before I had any understanding about partners and miles.

When I check in for my Delta flight do I tell them then about these three mileage plans? I called Delta to ask about the procedure, but all I understood was that yes, I was a Sky Miles member.

I really want to be certain that I get those Alaska Airlines miles. Thanks.
