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

Economy Lot G is one of three on-airport economy lots at Chicago O'Hare International Airport, operated by the Chicago Department of Aviation (CDA). It sits along Bessie Coleman Drive, the primary road running through the airport campus. The lot is accessed from the I-190 spur — follow signs for Economy Parking as you approach the terminal ring road.

Lot G is an open-air, uncovered facility. This matters in Chicago — winters bring snow, ice, and sub-zero wind chills. Your car will be fully exposed to the elements. There's no covered structure, no overhead protection, and no indoor section. If you want covered economy parking on-airport, Economy Lot F is your alternative (though it costs more at $22/day). For a full breakdown of all three economy lots side by side, see our O'Hare Airport Economy Parking Map for Lots E, F, and G.

The lot is served by its own ATS station, giving you a direct automated connection to the Multi-Modal Facility (MMF) and then to Terminals 1, 2, 3, and 5. You do not need to take a shuttle bus. The ATS is a free, enclosed people mover — which is especially helpful when it's -10°F outside.

How Much Does It Cost to Park in O'Hare Lot G?

According to O'Hare's official economy parking page, Economy Lot G costs $3 for the first hour, then caps at $15/day maximum. This makes it the cheapest on-airport lot at ORD. All rates below are per the Chicago Department of Aviation (verified June 2026).

For a 7-day trip, Lot G costs $105 total. That's a solid deal versus the Main Garages ($301) but still more expensive than top off-site options. Park 'N Jet at $8.95/day would cost just $62.65 for the same week — a savings of over $42.

Payment accepted: Cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay. You can also prepay online via SpotHero or flychicago.com for a guaranteed space — especially useful during summer and holiday peaks.

How Do You Get from Lot G to the Terminal?

Lot G connects to all ORD terminals via the free Airport Transit System (ATS) — an automated people mover that runs 24 hours a day, 7 days a week. Trains arrive approximately every 3-5 minutes. There is no separate shuttle bus for Lot G; the ATS is your transport.

Step-by-Step: Lot G to Your Terminal

1. Park and note your section/row number — Lot G is large and rows look similar.
2. Follow the signs to the ATS station within the lot (it's an enclosed walkway).
3. Board the ATS train toward the Multi-Modal Facility (MMF).
4. At the MMF, transfer to the terminal-bound ATS train for your terminal (1, 2, 3, or 5).
5. Ride to your terminal and follow signs to check-in and security.

Estimated total transit times from Lot G (based on ATS operating data and typical wait times):

• Terminal 1 (United): approximately 10-15 minutes total
• Terminal 2 (United Express, Air Canada, JetBlue): approximately 10-15 minutes total
• Terminal 3 (American Airlines hub): approximately 12-18 minutes total
• Terminal 5 (Delta, Southwest, international carriers): approximately 15-20 minutes total

These estimates include the walk to the ATS station, one possible transfer at the MMF, and the ride to your terminal. Add a few extra minutes during peak travel periods when platforms get crowded.

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

The ATS itself is fast — the automated train runs continuously and the ride from Lot G to the MMF takes just a few minutes. The total door-to-terminal time, however, depends on your timing and which terminal you need.

Travelers frequently report that the longest part of the journey is the walk to the ATS platform from a far section of the lot, plus any wait for the transfer train at the MMF. During normal hours, total transit time runs 10-20 minutes. During peak periods — holiday weekends, summer Fridays, early morning bank days — crowding at platforms can add 5-10 minutes.

One practical tip: leave the lot early. The TSA recommends arriving at least 2 hours before a domestic flight. With Lot G transit time and TSA security screening factored in, build in at least 25-30 minutes between leaving your car and reaching your gate. If you have TSA PreCheck, security lanes are typically much faster — but Lot G transit time stays the same.

Is Lot G the Cheapest Parking at O'Hare Airport?

On-airport, yes — Lot G at $15/day is the cheapest option available at ORD. But it's not the cheapest overall. Several off-site lots near Mannheim Road beat it on price while still offering free shuttles to all terminals.

Based on current rates (verified June 2026), Park 'N Jet O'Hare at $8.95/day and Routes Airport Parking at $9.95/day both undercut Lot G significantly. Even PreFlight Airport Parking at $12.95/day is cheaper than Lot G, and PreFlight includes EV charging, car wash, and luggage assistance. Off-site lots on Mannheim Road run free 24/7 shuttles every 5-15 minutes, with a 7-10 minute ride to ORD terminals.

The real advantage of Lot G is simplicity: it's on airport property, managed by the CDA, and connected by the ATS without any third-party shuttle coordination. For some travelers, that peace of mind is worth the extra few dollars per day. For others, the off-site savings are hard to ignore — especially on longer trips.
