Southwest is currently having a major meltdown (see e.g. https://www.cnn.com/travel/article/flight-cancellations-christmas-2022-winter-storm/index.html). I have a flight currently booked for January 2nd between two major Midwest cities. Will Southwest end up cancelling that flight? This question resolves based on whether the flight number originally booked flies as scheduled as reported by Southwest's flight status page, regardless of whether I actually end up taking that specific flight. If the flight's reported arrival time is at least 12 hours later than the originally scheduled arrival time I will also count that as effectively cancelled. Likewise if the flight occurs but never reaches its intended destination for any reason, that also counts as cancelled. The reason for cancellation/delay does not matter.

If the flight is cancelled or significantly delayed (as defined above, i.e. does not reach intended destination within 12 hours of the scheduled time) I will resolve YES.

Otherwise I will resolve NO.

If Southwest's website is so non-functional at resolve time that I cannot determine whether the flight occurred successfully then I will resolve YES.
