My only experience with a cert was through delta with a set value and they were eligible for miles and upgrades.

Thoughts on what these are and if I might still get MQMs but not miles? hopefully...a bit demoralized by being stripped of the perks and this back to back with another flight I have to take on American without status as Delta doesn't offer Bermuda. I know ... first world problems but the back of the bus middle seat by bathroom is not enhancing my joy of travel
