Want to see a lot of Elites all flying on the same flight? Try the DAL-IAH run on a Thursday or Friday afternoon, or at IAH on a Monday morning or Sunday afternoon.
I have had more than my share of those COEx flights that were an entire plane full of Elites. All angry because they didn't get to board first or get their "A" side seat. I just stand back and board when they tell me. It is not worth getting my limbs broken in the buffalo stampede.
