When does the perk "Complimentary auto-requested upgrades* where "*" denotes: *Benefit may not be available on all flights. come into play?
Just curious about this perks as it applies to all elite levels. Is it suppose to mean that if an upgrade isn't available, then it won't be an option? no-brainer. Or is it suppose to mean that upgrades are available but not complimentary at AA's discretions.
