Flight: AC134
Date: 04/05/2012
Cabin: J (eUpgrades cleared at the gate, with J7 at last check around noon)
Status: AC*SE and AC*E

Priority Boarding: GA announced that they would priority board SE and Business Class first, then E, then call by rows. They did enforce this, asking each passenger as boarding pass was presented.

This is the first time I've experienced this modified boarding procedure.
