The explanation of technology for Southwest’s woes, while true, also exposes a gap in people. They didn’t have enough people to rebuild their schedules by hand and were taking volunteers from within the company. There’s also a knowledge deficit.
There’s going to be a lot of IT spending ahead, and also a lot of work on culture ahead, for Southwest. Passengers will forgive them. But capital spending and culture are harder. And around a fifth of employees don’t have a long-term experience with the company against which to judge recent unpleasantness, including being stranded away from home for some time.
