Any additional insights into this is appreciated. A company is booking my flight using some sort of certificates that they reportedly get from delta. They could not provide me with ANY information on the certs other than there is a reference number that has three letters and three numbers. They state that it will not earn miles and insist that my medallion benefits will not do anything in that they will be not eligible for upgrades. 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
