Depending on the airlines flown, the difference can be much more than that
For example - as an AA PLT flying CX, the difference is between earning 0% in L and earning 225% in D.
and - trust me - they can become very addictive once you get the hang of how to plan your travel over a longer period than just one trip at a time.

)
