Yesterday, my flight on Southwest was cancelled. Neither of the cities that I flew to or from had significant issues. I rescheduled my flight for this morning, which was no longer non-stop. One of those flights was now cancelled.

Today, I noticed that Chicago MDW seems to have a lot more cancellations of Southwest flights, while ORD has mainly delays on other airlines. This has me wondering whether I can still rely on Southwest, or if I need to start booking on other airlines when I need to be somewhere urgently.
