I mentioned reverse pyramid boarding last week when I was meeting in Eagan. The problem with it for NWA is that Elites value pre-boarding and having the chance to stow rollerboards and carry-on luggage. If you let 60 or 85 Elites pre-board using a Reverse Pyramid boarding process doesn't work.

I don't expect NWA to change from Elite pre-boarding to reverse pyramid boarding anytime soon.
