Wow I just learned something new from this forum (a few new things actually) - the term "Branded Boarding Order" plus the graphic with eight (8!) Boarding Zones with fancy names that don't really mean anything (what does "Delta One" actually mean?) "One" is kind of like the way Southwest now has two separate meanings for "A." Next time I'm at a Delta gate I can quit trying to figure out what's going on from mere observation.
