I thought the article was pretty stupid. For one thing, comparing percentages is meaningless with no context.
For example, if airline ABC used to spend 40% of its operating expense on labor, and then made some changes and dropped that to 25%, is that automatically a good thing? It certainly isn't if it turns out that ABC doubled their non-labor expenses by blowing money on velvet seats, personal satellite TVs with 150 channels and offering three course meals (OK, revenue would rise, but this is just to demonstrate how one can twist numbers).
That is, in one sense, rising labor cost as a % of the total is actually good if it is the result of flat labor costs and non-labor costs being cut, assuming the customer experience isn't affected by non-labor cost cuts, and thus doesn't affect revenue.
The author harped on labor costs while hardly mentioning the fact that operating costs are down, which is amazing considering Southwest's expansion into the Northeast, where you would expect costs to rise.
The author also failed to mention the fact that more people are driving shorter distances now, IMHO in large part due to 9/11. Had Southwest been entirely short-haul in 2002-2004 like they were around 1980, they would definitely be losing money.
I'm sorry, but dealing with the TSA idiots is simply not worth it for a 30 minute flight. Next summer, for the first time, I will be taking my family on vacation in the car (around 600 miles to Ohio) rather than on an airplane.
It used to be that I would always fly from one city to another unless they were so close that there was no air service (e.g., SAT to AUS). Now I will drive 300 to 700 miles from my house depending on the destination (I won't drive to PHL but I will drive to TPA). My car doesn't give me lip and doesn't threaten to ground me if I don't bend over.
