I will go one step further, when CKs are called, we go up, scan our boarding pass...we get a thanks.....

Going back to your question........even if they did....so what? What would you like to see happen? If CKs aren't even getting much different in flight service, I don't think a different color boarding pass will matter much.

All the GA cares about is to get the plane out on time for a departure of 0 minute delay......AA elite status is the last thing on their minds...
