I'm waiting for my 2MM status also. Depending on who you talk to at Delta.

2 to 3 days.
End of this month.
End of this year.
There is no program for lifetime miles.
You can only get silver not gold in the million miller program.
You have to send a request by email.
You need to speak to someone on the phone.
You have to call Monday to Friday.
Don't worry I'll make a note so you get an upgrade at the gate.
GA "Sorry"
And according the following email received yesterday, it's already done.
"The primary account data that is necessary for determining tier status, mileage redemption and Million Miler status were combined first and is currently displayed when accessing your account information. This includes current and lifetime EQMs/MQMs and redeemable miles"

No one at Delta has a clue.
