I know that upgrades are based on status, fare class and then other things like DL Reserve Card, certain corp accounts etc. Question is where does econ comfort, if actually purchased at time of booking fall into the pecking order. Meaning, on an upcoming flight, I can buy a X fare which will put me at the tail end of the Diamonds or I can buy W. Does the W actually sit higher in the pecking order than coach fares if actually purchased ? Thanks
