What Is Chicago Airport Lot G and Where Is It Located?

Economy Lot G is one of three economy surface lots at O'Hare — alongside Lot E and Lot F — managed by the Chicago Department of Aviation (CDA). It sits along Bessie Coleman Drive on the northeast side of the airport campus, accessible from I-190 (the Kennedy Expressway spur that feeds directly into ORD).

Unlike the terminal garages, Lot G is not attached to any single terminal building. You park your car, then take the free ATS people mover to whichever terminal you need. The ATS stop serving the economy lots connects to the Multi-Modal Facility (MMF), which links to Terminals 1, 2, 3, and 5. This two-leg journey — shuttle stop to MMF, then MMF to terminal — is something first-time Lot G parkers often underestimate. Budget at least 15–25 minutes from your car to your departure gate.

Lot G is an outdoor, uncovered surface lot. There is no garage structure, no roof, and no wind barrier. Chicago winters are brutal, and a lot of travelers only realize this on the return trip when they're clearing ice off their windshield at midnight. Keep that in mind before choosing Lot G for a January trip.

How Much Does Lot G Parking Cost at O'Hare Airport in 2026?

Economy Lot G costs a maximum of $15/day, making it the most affordable on-airport option at ORD. The entry rate starts at $3 for the first hour, then caps at $15 for the full day. According to the official O'Hare economy parking page, this rate applies around the clock with no overnight surcharge.

Here's how Lot G stacks up against every other on-airport option, based on current published rates (verified June 2026):

Payment is accepted by cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay. You can also pre-pay online via SpotHero for a guaranteed spot, which is smart during peak travel windows.

How Do You Get from Lot G to the Terminal?

The free Airport Transit System (ATS) is your connection from Lot G to every terminal at O'Hare. The ATS is a fully automated people mover — no driver, no ticket needed, no cost. Trains run every 3–5 minutes, 24 hours a day, 365 days a year.

Here's the step-by-step process for first-time Lot G parkers:

1. Park your car and note your row and section number — Lot G is large and rows look identical at 2 a.m.
2. Follow signs to the ATS shuttle stop within the lot. Look for overhead signage — it's clearly marked, but give yourself a moment to find it.
3. Board the ATS train toward the Multi-Modal Facility (MMF).
4. At the MMF, transfer to the ATS line that serves your terminal (1, 2, 3, or 5).
5. Exit at your terminal's ATS station and follow signs to departures.

The ATS ride from the economy lot stop to Terminal 1 takes roughly 8–12 minutes depending on stops and transfer wait. Terminal 5 (the international terminal used by Delta, Southwest, Emirates, Air France, and others) may take slightly longer because it's the furthest point on the loop. Add a few extra minutes during the ORDNext construction period — active work on the new $1.3B Concourse D means some detour signage near Terminal 1 in 2026.

The full journey from car door to departure gate — including the walk to the ATS stop, the ride to MMF, the transfer, and the walk to your terminal — typically takes 15–25 minutes. Don't cut it close. Plan to arrive at the airport at least 2 hours before domestic flights and 3 hours before international ones, accounting for this transfer time plus TSA security screening.

How Long Does the Shuttle Take from Lot G to O'Hare Terminals?

On paper, the ATS runs every 3–5 minutes. In practice, many travelers report longer total transit times — especially during peak periods. This is one of the most common complaints about chicago airport lot g in user reviews, and it deserves a straight answer.

The ATS itself is reliable and fast. The issue is usually the walk from your parked car to the ATS stop, plus any transfer wait at the MMF. Here's a realistic breakdown by terminal:

• Terminal 1 (United Airlines): Approximately 10–15 minutes on ATS from the economy lot stop
• Terminal 2 (Air Canada, JetBlue, United Express): Approximately 10–15 minutes
• Terminal 3 (American Airlines, Alaska, British Airways): Approximately 12–18 minutes
• Terminal 5 (Delta, Southwest, Emirates, Air France, international carriers): Approximately 15–20 minutes

Peak travel periods — holiday weekends, summer Fridays, Sunday evenings — can add 5–10 minutes to the overall journey due to crowded platforms and busier transfers. Give yourself a buffer. If you have TSA PreCheck, your time inside the terminal is faster, but the lot-to-terminal transit time stays the same regardless.

Is Lot G Safe, and What Should You Know Before Parking There?

Lot G is an official, CDA-managed lot with security cameras and periodic patrols. That said, multiple traveler reviews mention spare tire theft as a recurring issue — this is not something competitors address directly, but it's a legitimate concern for longer trips.

Practical security tips for parking at Lot G:

• Do not leave valuables visible inside your car — bags, electronics, and loose items should be in the trunk before you arrive at the lot
• If your vehicle has an external spare tire mounted on the rear (common on trucks and older SUVs), consider a locking spare tire cover or cable lock
• Take a photo of your row and space number before walking away — this also timestamps your parking location
• Use the central rows rather than isolated perimeter spots when the lot is not full
• For extended trips of 7+ days, consider an off-site lot with an attendant on-site 24/7, like Park 'N Jet O'Hare ($8.95/day) or PreFlight Airport Parking ($12.95/day)

Accessible parking spaces are available in Lot G and are clearly marked near the ATS stop entrance. All payment methods are accepted at the exit lanes, including contactless options.

How Does Lot G Compare to Lot F and Lot E at O'Hare?

All three economy lots use the same free ATS connection, but they differ in important ways. Here's a direct comparison based on current CDA data (verified June 2026):

Lot F costs $7 more per day but gives you a covered structure — that's worth it in January or during a Chicago thunderstorm. Lot E splits the difference at $17/day but is also outdoor. If you drive an EV, Lot F is the clear choice since it has confirmed Level II charging stations. Lot G's EV charging situation is currently unconfirmed by official CDA sources — do not assume charging is available there.

Is Chicago Airport Lot G the Cheapest Parking Option at ORD?

Lot G is the cheapest on-airport option at $15/day. But off-site lots near ORD undercut it significantly. Based on our analysis of current rates, here's how Lot G compares to nearby off-site alternatives:

Park 'N Jet O'Hare at $8.95/day saves you 40% compared to Lot G over a 7-day trip — that's $42.35 back in your pocket. PreFlight Airport Parking at $12.95/day also saves money, adds EV charging, and includes luggage assistance. The off-site shuttle rides to ORD typically take 6–10 minutes from Mannheim Road lots.

Tips for Parking at Chicago Airport Lot G: What First-Timers Need to Know

No competitor currently walks you through the full Lot G experience step by step. Here's what actually helps on your first visit:

• Arrive early during peak periods. Lot G has significant capacity, but it fills faster than you'd expect on holiday Fridays, spring break weekends, and summer Saturdays. Arriving 30 minutes earlier than planned is cheap insurance.
• Screenshot or write down your row and space number. The lot is large, rows look identical, and arriving home exhausted at night is not the time to wander an outdoor lot searching for your car.
• Budget 20–30 minutes to reach your gate. This accounts for the ATS ride, the MMF transfer, and walking to security. Then add time for TSA screening on top of that.
• Check traffic before you leave home. I-190 and the Kennedy Expressway (I-90/94) experience heavy congestion during rush hour. Use the Waze live traffic map to plan your drive and avoid arriving late.
• Dress for weather on your return trip. Chicago winters mean your car will be cold, possibly iced over, and the walk to the ATS stop is outdoors. Keep a scraper in the car for winter trips.
• Pre-pay if you can. Use SpotHero or the flychicago.com parking portal to lock in your spot in advance — especially for holiday travel. Walk-up availability is not guaranteed during peak periods.
• Don't use Lot G for EV charging. EV charging in Lot G is unconfirmed. If you drive an EV, use Lot F or an off-site lot like PreFlight, which has confirmed EV charging.

O'Hare is in the middle of major construction through 2026 and beyond as part of the ORDNext expansion. The new $1.3B Concourse D broke ground in August 2025 and is now in vertical construction. Economy lot access via ATS remains unaffected, but allow a few extra minutes when navigating between terminals. Terminal 5 expansion was completed in 2025, adding 10 new gates and a 22,000 sq ft Delta Sky Club.
