Quick Questions About Departures at O'Hare
- Can my flight be delayed after boarding? Yes. It's very common to wait on the runway for 30 to 90 minutes before takeoff. This "runway traffic" is one of the airport’s biggest bottlenecks.
- What's security (TSA) like? It's a lottery. Lines can be long and staff behavior varies. Also, gate changes are very frequent, so keep checking the screens.
- Can I get dinner if my flight is delayed at night? Probably not. Most restaurants and shops close early (between 8 and 10 PM), leaving few options for late-night or delayed flights.
- How early should I arrive? Follow the rule of 2 hours for domestic and 3 for international flights. This buffer is crucial for handling security delays and long walks inside the airport.
Departing from O’Hare Airport means navigating one of the world’s busiest airspaces. The experience can be smooth, but it's often subject to unexpected variables that can cause stress.
This guide, based on recent experiences from thousands of travelers, gives you an honest perspective on the departure process—from security checks to takeoff—so you can manage expectations and plan your trip more effectively.
Real Challenges When Departing ORD
Beyond arriving on time, there are three key areas that define the departure experience at ORD. Knowing them in advance is essential.
Timing Factor: More Than Just Arrival Time
User insight: Arriving 2–3 hours early is more critical at O’Hare than at many other airports. Why? Delays don’t just happen before you reach your gate. A common frustration is the long wait on the runway before takeoff. It’s typical for planes, with all passengers boarded, to wait 30–90 minutes in long departure queues. This “runway traffic” is a bottleneck you should anticipate.
The Unpredictable Duo: TSA and Gate Changes
User insight: Going through security is a lottery. Many travelers report long, slow lines, even in TSA PreCheck lanes that can close unexpectedly. TSA staff attitude is hit-or-miss: some are praised for professionalism, but many complain of rude, apathetic, and inconsistent behavior. Add to this the high likelihood of last-minute gate changes. Stay vigilant—keep checking airline apps and information boards up until boarding.
Gate Area Wait: Seats, Outlets, and Food
User insight: After security, new challenges arise. Terminals—especially older ones—are often criticized for their lack of seating, forcing many to wait on the floor. Finding a working outlet to charge devices can be difficult. But the biggest warning? The food: most restaurants and shops close early (between 8 and 10 PM). If your flight is delayed until late, you’ll likely find few options for food or drink.
Key Tips for a Stress-Free Departure

Plan to Arrive with Plenty of Time
Due to potential traffic en route and internal delays, aim to arrive 3 hours early for international flights and at least 2 hours for domestic ones. Peak hours (6–9 AM, 11 AM–2 PM, 7–10 PM) are especially busy.

Manage Your Time Before Boarding
After clearing security, locate your gate before doing anything else. That way, you’ll know how much time you really have. Explore food and shops, but expect high prices. If you want a break from the crowds, airline lounges could be worth it, though availability and quality vary.
Pro tip: If you're flying late in the day, grab snacks or a drink as soon as you're through security. Don’t assume shops near your gate will still be open.
Double-Check Luggage Restrictions
To avoid costly surprises at the desk, confirm carry-on and checked baggage policies directly with your airline. Check their official site or app for weight limits, dimensions, and prohibited items.
