I know this is a basic question, but what I'm seeing doesn't match what I thought I understood about complimentary upgrades. I earned DM in Dec. My understanding this that PM and above are upgraded at the 5-day window. I have a flight in 3 days and I have yet to be upgraded. Yet the seat map shows 10 of 20 FC seats still empty and the flight info indicates that FC is available with a RUC. Could you explain what's happening and when those seats will next be released? Thank you.
