I'm willing to bet it'll be J & SE, followed by all other "priority" groups, then the rest (split into 3 zones). What it should be is:

1) J, SE & MM
2) E75, E50 & *G
3) E35, P25, PY, credit card & preferred seat purchasers
4 - 7) everyone else

35K shouldn't get to board with the 50 and 75s, despite AC calling it Elite. It's *S, which doesn't get you priority boarding.
