This could get interesting for the next few months. I'm not sure how many of the passengers out of HOU to DEN are O & D, but with the schedule optimization they could send a lot more connection traffic through HOU, increasing the number of flights to DEN, while allowing a drop in airfare since the costs could be in essence "subsidized" on the connection legs. I'm definately not a revenue management guy, but I do know the SWA people are really good at schedules and what the fare point is for certain cities. There has been a lot of research done through the years, and not just for SWA cities.
