We used to fly barber pole/mach buffet at SWA. Change in plans for whatever reason you want:fuel prices/former AF guys running the show/lousy ground service/ATC/whatever. So now the standard SWA profile is (depending on model aircraft) climb at basically 260-265/.68-74 mach, cruise at .74-78, then descend at .74-.78 crossover to 261. Mach if cruising in the 20's is around 72. Beancounters running the show.
