Of there, roughly 40,000 became charter DMs with 125,000 status miles annually or a similar segment requirement.

Beyond such similar data provided by airlines from time to time, carriers consider their FF numbers to be proprietary. In addition, it would be difficult to determine how many people have elite status on more than one carrier to attempt to get the distributions by individuals of total miles flown, rather than miles flown on a single carrier/alliance.
