Living in Chicago and frequently traveling for work in the Midwest, I always worry about flight delays or cancellation messages when winter arrives.

True to its nickname, the Windy City, when a snowstorm hits, O'Hare Airport comes to a complete standstill. What might seem like a light snowfall turns into a disaster movie the moment you step inside the airport. The news reports "massive flight delays," but within that one line are the intertwined stories of thousands of lives.

O'Hare is not just an airport; it is the heart of the U.S. aviation network. It is the hub for United and American Airlines, with thousands of flights departing from here every day. However, when the snow starts to fall heavily, that massive system collapses surprisingly easily. It seems like a great airport with many runways, but its sheer size means that if one part gets blocked, the entire system gets tangled like a domino effect.

On a snowy morning, checking the airport status on my app reveals that there are hardly any green indicators for on-time departures. Everything is orange for delays, followed by red for cancellations. The real problem is that you still have to head to the airport despite seeing that. The highway is already a parking lot on ice, and arriving at the terminal feels like stepping into a funeral home.

Inside the airport, it is utter chaos.

There are people stranded due to cancellations, those who came to pick someone up sitting in a daze, and I've seen young women crying multiple times.

People's attitudes vary widely. Some are almost negotiating with the staff, saying things like, "I have to go today," "It's a funeral," "It's a wedding," or "My child is home alone." The staff's expressions show they are already half-giving up.

The issue isn't snow removal; that happens overnight. The problem is de-icing. If there's even a little ice left on a plane's wings, it can't take off. So, de-icing one plane takes a long time, and during that wait, all the planes lined up behind it are stuck. That one line ultimately halts flights nationwide.

If Chicago is backed up, New York, Denver, Dallas, and Atlanta are all affected. When O'Hare stops, the skies over America come to a halt.

A few winters ago, I had to rush to LA and got caught in a major delay. It started with a 2-hour delay, then 4 hours. By the afternoon, it quietly changed to a cancellation. When I asked about alternative flights, they told me two days later. That day, O'Hare felt less like an airport and more like a temporary refugee camp.

After experiencing this a few times, Chicagoans become more aware of winter travel. When snow is forecasted, people postpone their plans, and those who travel frequently avoid winter trips at all costs. Still, Chicago snow can come without warning. Trusting the weather app can easily ruin your plans.

O'Hare is one of the best airports in the world. The facilities, staff, and systems are all top-notch. But in the face of nature, what does that really matter?

A few snowfalls can shake the entire U.S. aviation network. So every time I book a flight at O'Hare in winter, I silently pray. I hope that on that day, the snow will take a break. The longer I live in Chicago, the more I feel how small humans are in the face of nature each year.
