I checked the other day, and DL Management has not updated the Million Miler qualification page to reflect the new DM level; i.e., PM is the highest tier for which a Million Miler threshold is posted.

This has to prompt the question... is this an act of omission or an act of commission?

I am not aspiring to qualify at that level. I'll be satisfied when I shortly cross the 2 Million Mile threshold for the GM (shortly to become the new FO) "we'll give you annual elite status for as long we we choose to do so" complementary status.

It leaves me wondering though, what will happen to those of us who qualified before the rule change and are actually "lifetime" FOs, when DL management finally cuts the shriveled stem and drops the FO level from the program?

Silly question, they'll do what they did for the lifetime Crown Room memberships for Flying Colonels.
