Delta is the airline that abandoned me for 40 hours in ATL of all places, while Southwest has never let me down. If you had asked me a week ago which of the two was more reliable, I would have told you Southwest and I would have meant it absolutely.
How would you have me judge them? I don't know anything about how to run an airline and I wouldn't even know where to start if you asked me to look up which of the two had a more resilient business model. You can't really expect any random air traveler to have an opinion on airlines better informed than their personal experiences. I think most people would struggle to tell you something so basic as what sort of plane they were even sitting in.
