Instant Upgrade Fares when Downgrading Status
I need to book a MCO trip and the lowest fares are K-class, which are eligible for instant upgrades for MVP Gold and higher. However, next year I'm dropping from MVPG to MVP (MVP is not eligible for instant upgrades on K class...only Y and B which is about $500 more each way). U class is not available currently. If I purchase and waitlist now, will they honor the instant upgrade if U class becomes available? Or do I need to use some of my Gold Guest Upgrades?
alaska.com simply says:
"If you have purchased the qualifying fare for your Elite level, and upgrade space is available on your flight, you will be upgraded immediately. If there are no upgrades available for your flight, you will be placed on the upgrade waitlist."
