If you’re standing in Terminal 3 right now staring at the departures board, you’ve probably noticed the numbers aren't looking great. Chicago weather has a funny way of making travel plans feel more like a suggestion than a schedule. Chicago O'Hare flight delays today are largely being driven by a stubborn system of light snow and biting winds that have settled over the airfield this Sunday.
Honestly, it’s not just the snow. It’s the de-icing queues.
Current conditions at ORD show a temperature of 17°F, but with the southwest wind kicking at 10 mph, it feels more like 5°F. That's cold enough for de-icing fluid to become your best friend and your worst enemy at the same time. The FAA has already reported general departure and arrival delays, mostly hovering around 15 minutes or less for now, but those numbers are slippery.
What the Boards are Saying Right Now
As of midday on January 18, 2026, the statistics show a system under pressure. Out of roughly 2,550 total flights scheduled for the 24-hour period, we’re seeing about 145 delays and 19 cancellations.
Most of the friction is happening with arrivals. About 84 incoming flights have been flagged for delays, compared to 61 departures. Why? Because when the visibility drops—even a little—the spacing between landing aircraft has to increase. It’s a literal bottleneck in the sky.
Here is the breakdown of how the delays are stacking up:
Around 47 flights are sitting in that 15 to 30-minute window. This is the "annoying but manageable" zone. You still have time to grab a second coffee. Then you have 37 flights pushed back 30 to 45 minutes. The real headache is the 61 flights currently delayed by 45 minutes or more. If you're in that last group, you’re likely looking at a missed connection or a long afternoon in the lounge.
The Weather Factor: Sunday's Snow Squalls
The forecast for the rest of today, January 18, isn't exactly a beach day. We are looking at a high of 19°F and a low of 6°F tonight.
The light snow is expected to continue through the afternoon with a 25% chance of precipitation. While a 25% chance sounds low, in Chicago airport terms, that’s enough to keep the snow plows on standby and the de-icing pads busy. The wind is the real kicker. It’s coming from the southwest, which can sometimes create crosswind issues on O'Hare's specific runway configuration.
Air Canada flight 510 to Toronto (YYZ) has already been marked as canceled, and we're seeing some ripple effects from ground stops earlier in the week.
Ground Stops and Airspace Congestion
It’s important to remember that O'Hare is a hub. That means if things go south in New York or Philly, Chicago feels the burn. Today, the FAA has flagged probable ground stops or delay programs for LGA (LaGuardia) and possible stops for PHL (Philadelphia) and EWR (Newark).

If your flight is heading east, your delay might not even be Chicago’s fault. You’re just waiting for a parking spot to open up on the East Coast.
The airport is currently in the middle of a massive expansion. American Airlines and United are essentially in an arms race to dominate the gates here. American recently announced 100 new daily departures for the spring season, aiming for 500 peak daily flights. While that’s great for future travelers, it means the airport is operating at near-maximum capacity. There is very little "slack" in the system. When a snow squall hits, there’s nowhere for those extra planes to go.
Tips for Survival at ORD Today
Basically, if you haven't left for the airport yet, check your airline's app. Don't trust the third-party trackers alone; they can lag by ten minutes, and in that time, your flight could go from "On Time" to "Canceled."
- Check the de-icing status: If you’re on the plane and the pilot mentions de-icing, add at least 20 minutes to your mental arrival clock.
- Terminal 5 is a different beast: If you’re flying international, give yourself even more time. International flights are currently seeing a slightly higher cancellation rate (around 8%) compared to domestic routes during this winter stretch.
- The "Incoming" trick: Look up your specific tail number on a tracking site to see where your plane is coming from. If the plane that’s supposed to take you to Denver is currently stuck in Minneapolis, you’re going to be delayed, even if the gate agent hasn't announced it yet.
For those stuck for a while, Terminal 2’s "Butch O'Hare" exhibit is a decent way to kill fifteen minutes. Otherwise, find a seat with a power outlet early. They disappear fast when the delay numbers start climbing.
Next Steps for Displaced Passengers:
If your flight gets canceled, don’t join the 100-person line at the service desk. Use the airline’s app to rebook yourself immediately, or call the carrier’s international support line—they often have shorter wait times than the domestic ones. If you are delayed more than three hours on an international leg, keep your receipts. Depending on the carrier, you might be eligible for compensation under specific aviation rights, though weather is often cited as an "extraordinary circumstance" that lets airlines off the hook for cash payouts.
Check your gate's "Updated At" time frequently. In weather like this, a 15-minute delay can turn into a 2-hour delay in the blink of an eye. Stay warm, stay caffeinated, and keep an eye on those southwest winds.
