Having flown SouthWest hundreds of times, their performance is quite good when things work. However, in my experience, when things fail their performance suffers worse than several other airlines. It think it's because they intentionally run their systems to maximize efficiency which means less resilience to unexpected failures. Years ago, they compensated for this with generally lower prices. However, in more recent years, I've noticed their pricing isn't nearly as advantageous compared to competitors. Yes, if you're one of the first 20% to book a flight six weeks in advance, and can accept little flexibility in terms, and are willing to go at a less desirable time, there are still deals to be had. But in any other scenario I've found United, American, Delta, etc to sometimes actually be cheaper, which was previously rarely the case.
