Elliott Investment Management‘s move on Southwest Airlines continues to elicit industry chatter. The initial reaction was surprising, but it soon became accepted that Southwest needed a shakeup.  A key argument of this thinking goes like this: when you also consider that only one out of eight of the company’s top executives have worked anywhere else but Southwest Airlines, you get a sense of where the staleness is coming from.

Moreover, when the former CEO is still connected to the company as the board’s chairman, there is the danger of creating an echo chamber that lacks the benefit of external input.  Sounds reasonable, right?

Is there any data that supports this?  Does operational data support the idea that Southwest Airlines is operated at a sub-optimal level?

Let’s start with the DoT’s Ontime dataset to see how the airlines stack up.

Southwest arrival delays are below average, which is a positive outcome, especially considering it is the largest traffic carrier in the domestic market. Looking at the Ontime data for the first quarter of 2024, we see that Southwest performs comparatively well.

The data suggest that Southwest operates a better-than-average schedule performance.  Reviewing schedule padding, we see that Southwest pads more than its peers. This is not a positive.

Next, what does Southwest’s cost look like compared to its peers?

Among the Big Four, Southwest is the low-cost producer. It’s not the lowest cost overall, but it’s still ~13% below the industry average. Given the critical mass Southwest brings to the market, it can deploy that cost advantage across a wide swath of the market.

To its credit, Southwest’s crews try to save time, as the table shows.

Southwest traditionally focused on the 737-700 for most of its capacity but now has more -800 and MAX8s in service. Yet this gauge growth does not seem to have been a negative. The airline operates at high load factors of around 80%

Moreover, the MAX 8 helps drive up the average stage length and lower fuel burn.

When Southwest is compared with its industry peers regarding fuel and total air costs, we can conclude that the airline is performing well.

One last table shows operating costs per air hour, and Southwest has the lowest operating cost per air hour.

Is there room to improve Southwest’s operations? Yes, but it would be at the margins. This industry is very competitive, and competitive advantages emerge quickly. The same applies to disadvantages. The operational data shows Southwest is at least as competent as its peers, and by several measures, it is the best operator with the lowest cost.

It could be argued that Southwest’s biggest challenges are perhaps at a strategic level.  For example, should it stay with one aircraft model? Can Southwest exploit technology better than it does?

The numbers don’t reflect the corporate culture. And we submit that even with all the tweaks needed, and there are several, the corporate culture keeps the airline operating so effectively.  If that culture gets disrupted, then all bets are off.
