If you are formally recognized as having gotten elite because of activity by Oct. 31, you will get all the E benefits including the 15k and 20k threshold certs.

If you made 35k after Oct 31 you will be recognized as E on boarding passes for flights you book (or for flights you've called in to have your AP# re-entered to show new status), and you will be E for purposes of priority boarding and standby and things like that.

But you don't get to select a 2006 package, you won't get certs, and you won't get the card.

A printout of your AP balance and a boarding pass with *E on it should usually get you into MLL, but don't expect to get Star Gold recognition from other Alliance members.

This is from the collective experience of FTers. You won't find a formal policy written anywhere.
