Looking for a Chicago O'Hare smoking area? Here's the honest answer up front: there is no smoking area after security at ORD not in any terminal, not in any lounge. Smoking is only permitted outside the terminal buildings. The good news is that O'Hare is one of the easier large US airports to step out of and re-enter, and there's a comfortable insider option most travelers don't know about. This guide covers where the outdoor areas are, what leaving the secure area actually costs you, and the rules for vaping and IQOS.
Chicago O'Hare Smoking Policy
Smoking at ORD is governed by the Smoke Free Illinois Act, in force since 2008, and by the City of Chicago's own clean indoor air rules. Smoking is banned in all enclosed areas of the airport check-in halls, concourses, boarding gates, restaurants, bars, airline lounges, restrooms, enclosed walkways, and enclosed parking areas. There are no indoor smoking lounges or glass smoking cabins anywhere at O'Hare.
Illinois law also sets a buffer around the buildings: you must stand at least 15 feet (roughly 4.5 metres) away from entrances, exits, windows that open, and ventilation intakes. This is why the ashtrays outside the terminals are positioned away from the doors rather than right beside them.
Good to Know
Chicago includes e-cigarettes in its indoor smoking restrictions, so vaping is treated exactly like a conventional cigarette. That means a discreet vape at the gate isn't a grey area at O'Hare — it's the same rule, with the same consequences.
Where Are the Smoking Areas at Chicago O'Hare?
Every place you can legally smoke at ORD is outdoors and on the public side of security. There is nothing available once you've been screened, which makes the decision simple but the timing important.
Before Security
The only optionDesignated outdoor areas sit along the terminal kerbsides, on the arrivals and departures levels. Ashtrays and receptacles are provided, and the spots are set back from the doors to satisfy the 15-foot rule.
Best for: Departing passengers before check-in, and anyone who has just landed.
Access: All terminals, on the public side of security.
After Security
Not availableThere are no smoking rooms, terraces, or ventilated cabins on the airside at O'Hare. Airline lounges are indoor spaces and therefore smoke-free as well, including premium and international lounges.
Your options: Exit and be re-screened, or wait until you land.
Note: This applies to vapes and heated tobacco too.
The Short Answer
No, you cannot smoke after security at Chicago O'Hare. Use the outdoor areas before you go through screening — or be prepared to leave the secure area and queue for security a second time.
The Outdoor Smoking Areas: What to Expect
O'Hare handles the outdoor side of this reasonably well. Rather than one hidden corner, there are marked spots outside each terminal with proper ashtrays, so you rarely have to hunt for somewhere to stand.
Arrivals Level
Where you'll end up if you've just landed. Step out from baggage claim and walk past the pick-up lanes to reach the ashtrays.
Departures Kerbside
The closest option before check-in. Both kerbs are active traffic lanes, so expect noise and moving vehicles either way.
Mind the 15 Feet
Standing too close to a doorway is what gets people asked to move. Walk to the ashtray rather than stopping at the exit.
The Insider Option: The Airport Hotel Terraces
This is the trick experienced connecting passengers use, and it turns an unpleasant twenty minutes on a kerbside into an actual break. The Hilton Chicago O'Hare sits directly across from the core terminals and is reached through the airport's underground pedestrian walkway system, so you never step outside into the weather to get there.
Its bar, restaurant, and coffee lounge are open to non-residents, and the property has outdoor terrace space where smoking is possible. Expect airport-hotel prices, and expect the walkway signage to take a little concentration to follow but it's a far more civilised place to spend a long layover than the departures kerb.
Using the Hotel Route
How It Works
- Exit the secure area and head for the underground pedestrian walkways.
- Follow the signs towards the hotel and the parking structure.
- Use the bar, restaurant, or lounge as a non-resident.
- Allow plenty of time to walk back and clear security again.
Worth Knowing
- Indoor walkway route — useful in Chicago winters.
- Food and drinks are priced like an airport hotel.
- Close to the core terminals; from Terminal 5 take the ATS train first.
- Best suited to layovers of three hours or more.
Practical Note
Hotel policies and terrace layouts change, and outdoor areas may be closed in bad weather or for private events. Treat this as a comfortable option to check on arrival rather than a guaranteed facility.
Leaving the Secure Area and Coming Back
Because there's no airside option, the real question at ORD isn't where the areas are it's whether stepping out is worth it. You can leave any terminal and return with your boarding pass, but you will be screened again from scratch.
O'Hare is one of the easier big US airports for this: the exits and re-entry checkpoints are close together, and your checked bags stay with the airline. What you're gambling on is the security queue, which at ORD can swing from five minutes to well over half an hour depending on the time of day.
Makes Sense If
- You have three hours or more before boarding
- You have TSA PreCheck or CLEAR
- You're flying from Terminals 1, 2, or 3
- It's the middle of the day, not a morning peak
- You're travelling with hand baggage only
Think Twice If
- Boarding starts within 90 minutes
- You're departing from Terminal 5 and need the ATS
- The security hall is visibly backed up
- It's a winter evening with severe weather
- Your gate is at the far end of a long concourse
Important Warning
Don't smoke or vape in an airport restroom or stairwell. It sets off smoke detectors, can delay an entire concourse, and smoking in a prohibited area is an offence under Illinois law that carries a fine.
Can You Smoke During a Layover at O'Hare?
Yes, but only by leaving the secure area. How sensible that is depends almost entirely on how much time you have and which terminal you're in.
Under 2 Hours
Don't Risk ItExiting, walking to an ashtray, and re-clearing security can easily consume an hour at a busy time. That's your entire connection.
Stay airside and use nicotine gum, pouches, or a patch to bridge the gap.
2–4 Hours
Possible, With CareWorkable if you go straight out and straight back. Check the security wait time on the airport app before you commit to it.
Use the kerbside areas nearest your terminal, not the hotel keep it short.
Over 4 Hours
Go to the HotelNow the underground walkway to the airport hotel becomes worthwhile: a seat, a coffee, and terrace space instead of a traffic lane.
Set an alarm for your return and allow a full hour to get back through security.
International Connections
The US has no international transit corridor, so passengers arriving from abroad normally clear immigration and customs at O'Hare no matter where they're flying next. That puts you on the public side of the airport, which means you can use the outdoor areas before re-checking any bags and going through security for your onward flight. Build the queue time into your connection.
One exception: if you flew from a US preclearance airport Dublin, Shannon, Abu Dhabi, or the major Canadian airports — you cleared US immigration before departure and arrive at ORD as a domestic passenger, on the airside. In that case you'll need to exit and be screened again like everyone else.
Terminals and the ATS Train
O'Hare's terminals matter here because they change how far you are from the exit and from the hotel walkway. Terminals 1, 2, and 3 form the connected core; Terminal 5 handles much of the international traffic and sits apart from them.
Terminals 1–3
The core terminals, close to the underground walkways and the hotel route. Exiting and returning here involves the least walking.
Terminal 5
Set apart from the core terminals. Reaching the hotel means an extra ATS ride each way, so budget more time.
The ATS
The free Airport Transit System train links the terminals on the public side, running around the clock.
Construction Note
O'Hare is in the middle of a long-running terminal redevelopment programme, so walkways, kerbside layouts, and signage change from year to year. Check the current terminal maps before relying on a route you used on a previous trip.
Can You Vape at Chicago O'Hare?
No — not indoors, anywhere. Chicago folded e-cigarettes into its clean indoor air rules, so vaping is prohibited throughout the terminals in exactly the same way as smoking. Gates, restaurants, restrooms, and airline lounges are all off limits.
If you want to vape, you need to be outside the building in a designated area, on the public side of security. Discretion isn't a defence here: the restriction is written into city rules, not just airport policy.
Inside the Terminal
Vaping is prohibited in concourses, gate areas, lounges, restaurants, and restrooms.
Outdoor Areas
The designated kerbside spots, at least 15 feet from any doorway, are where vaping is permitted.
Carrying Your Vape
E-cigarettes and spare batteries must travel in your carry-on baggage, never in checked luggage.
E-Liquid and Security
E-liquid counts as a liquid at the TSA checkpoint: containers of up to 3.4 oz (100 ml), all fitting inside one quart-sized clear bag. Larger bottles belong in checked baggage.
Battery Reminder
Spare lithium batteries must be in your carry-on and protected against short circuits. Devices should be switched off and secured so they can't activate accidentally in a bag.
Can You Use IQOS or Heated Tobacco Products?
Heated tobacco devices such as IQOS and glo warm tobacco rather than burning it, which leads some travelers to hope for an exemption. There isn't one at O'Hare: they fall under the same indoor prohibition, so they can only be used in the outdoor areas outside the terminals.
Indoor Use
Using heated tobacco anywhere inside the terminals is prohibited, including at the gate.
Availability
Heated tobacco consumables are far less widely sold in the US than in Europe or Asia, so bring your own supply.
Best Practice
Treat the device exactly like a cigarette: outdoors only, and well back from the doors.

Tips for Smokers Traveling Through O'Hare
O'Hare rewards planning more than most airports, precisely because there's no airside fallback. These tips come from the reality of connecting through it.
Plan It Before Screening
The single most useful habit at ORD. Take your break outside before check-in, because there's no second chance airside.
Respect Chicago Weather
Winter here is severe, with wind chill well below freezing. Keep your coat accessible rather than packed in the overhead bin.
Check Security Wait Times
Look up the current checkpoint wait before you decide to step outside. It's the one number that determines whether it's safe.
Pack an Alternative
Nicotine gum, lozenges, or pouches are permitted airside and make a short connection far more bearable.
Avoid Enclosed Spaces
Smoke detectors are sensitive, the fine is real, and a false alarm can disrupt an entire concourse.
Keep Your Boarding Pass
You need it to get back through security, so have it on your phone and charged before you head outside.
Common Mistakes to Avoid
Avoid These Mistakes
- Assuming a big hub like O'Hare must have an airside smoking lounge somewhere.
- Stepping outside on a tight connection without checking the security queue.
- Stopping right outside the doors instead of walking to an ashtray.
- Vaping quietly at the gate and assuming it's tolerated.
- Heading for the hotel from Terminal 5 without allowing for the ATS ride.
- Packing your vape or spare batteries in checked baggage.
Make Your Layover More Comfortable
If there's no smoking area airside, the next best thing is a comfortable place to wait. That's exactly what a lounge or a meet & greet service is for.
Turn a Long Wait Into a Break
Airport lounge access at O'Hare gives you somewhere quiet to sit, eat, and work between flights — particularly valuable at an airport where stepping outside costs you a security queue.
Meet & Greet service adds personal assistance through check-in, screening, and the terminals, which helps a great deal during ORD's peak periods and ongoing construction.

Chicago O'Hare has no smoking area after security, and that isn't going to change — the ban comes from Illinois law and Chicago city rules, not airport preference. Use the outdoor areas before you go through screening, stand at least 15 feet from the doors, and treat vapes and IQOS exactly like cigarettes. On a long layover, the underground walkway to the airport hotel is the most comfortable option going. On a short one, a packet of nicotine gum will serve you far better than a dash for the exit.
