Love the new procedure.
One thing that hasn't changed: When my upgrade has not cleared, I am always seated near the front of the Y section, and typically am among the first to board when Group 1 is called, I do this primarily to ensure I have adequate overhead space for my carryon (I don't want to have to walk backwards after we land), but I get the added benefit of watching how many of our fellow passengers are inconsiderate during the boarding process, either because they stow their carryons in a way that takes up the most space possible in the overheads as opposed to the least space, or because they don't get the concept of stepping out of the aisle to allow others to pass. On Friday, I boarded a completely full 737 DFW-MSY, and got to watch as three passengers who boarded just after me blocked all other passengers from boarding while they stood in the aisle and discussed which of their three seats each of them should take -- who wanted the aisle, who should sit next to whom, etc. It almost caused me to rethink my very firm belief in gun control.
