My only "objection" is the statement that Lifetime Miles are "meaningless with no value." I find it interesting to see how many lifetime miles I have accrued since inception. Very informative for me.
What is the value to you of this information? You can't redeem them. They don't count towards any status. They don't even really "equate" to anything, given that they have such an unusual heritage (being made up from different accumulators from different heritage programs).
