As someone whose Southwest flight was cancelled, there's one important thing to consider with Southwest besides risk of cancellation - Southwest does not have reciprocity with other airlines. After my flight was cancelled, I was told they couldn't rebook me until two days later (when I was scheduled to return). They also offered a whopping $200 in Southwest credit, even though I ended up having to spend $600 to get to where I was going via United. So don't just factor in risk - factor in the impact of cancellation, which is much, much worse with Southwest, particularly when they have large-scale failures like this where everyone is trying to rebook the same few flights.
