I wasn't even on the list
When I check in Thursday night for my Friday morning flight on Delta, it asked me if I wanted to be on the Upgrade list for both of my flights. I of course clicked where it said to add me to the list. When I arrived at the airport, I wasn't on the list. I really miss the Northwest days. They would automatically put me on the list and I usually got upgraded to first. I guess Delta doesn't reciprocate with MVPG's from Alaska.
I'm flying Delta again in December. Let's hope they honor upgrading Alaska elites.
