Traveling to the US on Christmas Eve 2022. Seattle airport paralysis Let's safely go to Las Vegas

I kept imagining in my head whether I would be able to fly because the Seattle airport was paralyzed by the greatest snow storm or what to do if the flight was canceled in Seattle, and I was fully prepared to eat and sleep while waiting.
Luckily, like a Christmas miracle, the temperature rose and all the runways opened.
I would like to express my condolences to those who suffered damage due to this weather.
