I have yet to actually fly on a real "Polaris" seating arrangement. All my routes seem to be on PMCO equipment.
I have to admit, the Delta Suites concept has taken ALL of my excitement about the Polaris seats away. I feel that the "suites" concept make all of the seats equally good...whereas on the United config, I know I'd be anxiously trying to snag the single seat that is closest to the window (vs the one where you sit dangling into the aisle)
