However, I think the cost is upward of $1 million/gate, so I don't know that saving 5-10 minutes is worth it, even when you consider the interest on an airplane on a per-minute basis.
And even if it is worth it sometimes, it's probably only practical at a major hub gate (where it'll get the most use out of itself). Which makes it probably more suitable to a legacy with only a few hubs than for Southwest with its focus on point-to-point.
