Economy Lot G is O'Hare International Airport's most affordable on-site parking option (tied with Lot H), capping out at $16 per day for open-air, self-park spaces. If you're searching for O'Hare airport parking economy G, here's the short answer: it's one of the two cheapest lots the airport runs, connected to every terminal by a shuttle bus and the free Airport Transit System (ATS), and it's a solid pick for trips of two days or longer. At $16/day, a five-day stay runs $80 total, compared to $215 at the main terminal garages, a savings of about 63% based on published Chicago Department of Aviation rates (verified October 2026).

• Daily rate: $3 for the first hour, then a flat $16/day maximum, tied with Lot H for the lowest on-airport rate at ORD

What Is O'Hare Economy Parking Lot G and Where Is It Located?

Economy Lot G is an open-air, self-park lot on the grounds of Chicago O'Hare International Airport (ORD), operated by the Chicago Department of Aviation (CDA). It sits on airport property and is accessible via the internal airport road system. You do not leave airport grounds to use it.

Lot G reaches the terminals by a shuttle bus to the Multi-Modal Facility, where you board the Airport Transit System (ATS), O'Hare's free automated people mover. The ATS connects the Multi-Modal Facility to Terminals 1, 2, 3, and 5 and the Kiss 'n' Fly drop-off area. Buses and the ATS run every 5 to 10 minutes, 24 hours a day. You never need a rideshare to reach your terminal from Lot G.

To reach Lot G by car, follow the airport's internal signage from I-190 (the Kennedy Expressway spur that feeds directly into ORD). Economy lot signs are clearly marked throughout the airport approach roads. If you're coming from Mannheim Road (IL-45) or Irving Park Road, follow signs for Economy Parking once you're on airport property. For real-time navigation, check real-time traffic on Waze before heading out — especially during morning rush hours when I-190 can back up significantly.

Lot G is an open-air, uncovered lot. It does not have a parking garage structure. Accessible parking spaces are available with clearly marked spots, per CDA policy. The lot is part of O'Hare's roughly 18,000-vehicle total parking capacity across all garages and economy lots.

How Much Does O'Hare Airport Parking Economy G Cost? (2026 Rates)

Lot G uses a tiered hourly rate that quickly maxes out at a daily flat cap. Based on current rates published by the Chicago Department of Aviation (verified October 2026):

• First hour: $3
• Daily maximum: $16 (the rate stops climbing after the daily cap is hit)

There is no published weekly maximum or monthly rate for on-airport economy lots. You simply pay the $16/day cap for each 24-hour period. A full week in Lot G costs $112. That compares favorably to Economy Lot F at $30/day ($210/week) and the terminal garages at $43/day ($301/week). See the full breakdown below. Off-site rates in the table are for a 7-day stay booked ahead and change by date.

One thing to know about holiday pricing: Lot G, like all CDA-operated lots, does not officially publish holiday surcharges. However, the lot frequently fills to capacity around Thanksgiving, Memorial Day, and Christmas week. When it's full, you may need to try Lot H (same rate) or covered Lot F at $30/day. Booking an off-site lot in advance is the surest way to lock in a space and price during peak periods. For a deeper look at all on-airport economy lot rates, see our O'Hare airport economy parking rates guide for 2026.

How Does the Lot G Shuttle Work — Frequency, Hours, and Route?

Lot G does not connect to the terminals directly. A shuttle bus takes you from the lot to the Multi-Modal Facility, where you board the Airport Transit System (ATS), O'Hare's free, fully automated people mover. Buses and the ATS run every 5 to 10 minutes, 24 hours a day, with no schedule to memorize.

The ATS route loops through all major stops on airport property:

1. Multi-Modal Facility (Economy Lot F; shuttle buses from Lots G and H; buses, Metra connection)
2. Terminal 1 (United Airlines hub: Concourses B & C)
3. Terminal 2 (United Express, Air Canada, JetBlue: Concourses E & F; also the CTA Blue Line station)
4. Terminal 3 (American Airlines hub: Concourses G, H, K & L)
5. Terminal 5 (International terminal: Delta, Southwest, Emirates, Air France, and more)
6. Kiss 'n' Fly drop-off area

The typical ATS ride from the Multi-Modal Facility to Terminal 1 takes around 7 to 10 minutes, depending on how many stops the train makes, plus the shuttle bus ride from Lot G. Reaching Terminal 5 may take a few minutes longer since it's a separate loop. Add a few extra minutes in 2026: active ORDNext construction on the new Concourse D near Terminal 1 can occasionally cause brief pedestrian detours inside the terminal after you arrive.

There's no last bus or last train to worry about. The Lot G shuttle bus and the ATS run 24 hours. This is a genuine advantage over most off-site lots: Crowne Plaza, Hyatt Place and Marriott Suites run shuttles every 30 to 40 minutes with no overnight service, Super 8 has no shuttle at all, and only Pride and Routes run on-demand shuttles 24 hours.

How Do You Pay for Parking at O'Hare Lot G?

Paying is straightforward. You take a ticket on entry and pay before returning to your car. Here's the step-by-step process for first-time visitors:

1. Entry: Pull up to the Lot G entrance gate and take a paper ticket from the machine. The gate rises and you park anywhere in the open lot.
2. Take the shuttle bus to the Multi-Modal Facility, then the ATS to your terminal. Leave your ticket in the car or take it with you; you'll need it on the way out.
3. On your return: Before going back to your car, use one of the Pay-on-Foot stations in the ATS terminal area or near the lot exit. Insert your ticket, pay the fee, and the machine returns a validated ticket.
4. Exit: Insert your validated ticket at the exit gate within the allowed grace period (typically 15 minutes). The gate opens and you're on your way.

The CDA accepts the following payment methods at Lot G:

• Cash
• Visa, Mastercard, American Express, Discover
• Apple Pay and Google Pay (contactless tap)

There is no mobile app pre-booking for Lot G directly through the CDA. The lot operates on a first-come, first-served basis. If you want a guaranteed space with a locked-in rate, your best bet is to pre-book an off-site lot through a platform like Triply's ORD parking search before your trip.

How Does O'Hare Airport Parking Economy G Compare to Other Lots?

Lot G is the cheapest on-airport option, but it's not always the best choice for every traveler. Here's how it stacks up across the most important factors:

Lot G vs. Economy Lots H and F

• Economy Lot G ($16/day): Cheapest on-site option, tied with Lot H. Open-air, no cover. Best for budget travelers on trips of 2+ days.
• Economy Lot H ($16/day): Same price as Lot G. Credit card only. Like Lot G, it runs a shuttle bus to the Multi-Modal Facility for the ATS.
• Economy Lot F ($30/day): Covered parking. If rain or snow protection matters to you, the extra $14/day buys a roof. Best for longer winter trips.

Lot G vs. Terminal Garages

• The Terminal 1, 2, 3, and 5 garages cost $43/day — nearly 3x the price of Lot G. They're covered and connected directly to the terminal, saving the ATS ride. For short trips (under 4 hours), the garage makes sense. For overnight or multi-day stays, Lot G wins easily on price.

Lot G vs. Off-Site Lots Near O'Hare

• Super 8 Chicago O'Hare Airport (about $11/day): Cheaper than Lot G, but no shuttle; you take an Uber or Lyft to the terminal.
• Crowne Plaza (about $13/day): Cheaper than Lot G, with a complimentary shuttle every 30 minutes from 5 AM to 9:30 PM. Availability is limited.
• Pride Airport Parking (about $15/day) and Routes Airport Parking (about $16/day): About the same price as Lot G, with on-demand shuttles 24 hours. Routes is a valet lot (you leave your keys); at Pride, part of the price is paid at the lot.
• Hyatt Place Chicago/O'Hare (about $17/day) and Marriott Suites O'Hare (about $19/day): Cost more than Lot G. Hyatt Place's shuttle runs every 40 minutes from 5 AM to 10:30 PM; Marriott Suites' runs every 30 minutes from 5 AM to 10 PM.

The trade-off with off-site lots is the shuttle dependency. You're relying on a lot shuttle (or, at Super 8, a rideshare) rather than the ATS, and most of these shuttles don't run overnight. If a shuttle is late at 5 a.m., you feel it. For detailed comparisons of all off-site options near ORD, see our ORD off-airport parking guide.

Can You Reserve Lot G in Advance — and Should You?

No — Economy Lot G cannot be reserved in advance through the Chicago Department of Aviation's official booking system. It operates on a walk-up, first-come, first-served basis. This matters most around high-demand travel dates.

During peak holiday periods (Thanksgiving week, the week before Christmas, Memorial Day weekend, and Fourth of July), Lot G fills early. Travelers arriving mid-morning on busy travel days have been redirected to other economy lots, including covered Lot F at $30/day. If you need certainty about having a space, here are your options:

• Book an off-site lot in advance: off-site lots booked on Triply include free cancellation with a full refund up to 24 hours before check-in. You lock in the rate and the space.
• Use SpotHero or Triply: Both let you book off-site lots near ORD days or weeks ahead.
• Arrive early on busy dates: If you're committed to Lot G, arriving before 8 a.m. on peak travel days dramatically improves your odds of finding a spot.

For travelers flying out of Terminal 3 (American Airlines) or Terminal 1 (United), the shuttle bus and ATS ride from Lot G is fast enough that the convenience gap vs. the garages is small. The $27/day savings over the terminal garages adds up quickly on a week-long trip. See the O'Hare airport parking reservation guide for the full breakdown of what can and can't be pre-booked at ORD.

What Are the Best Tips for Saving Money on O'Hare Economy Parking?

Lot G is already one of the cheapest options at O'Hare, but you can go further. Here are the most effective strategies based on our analysis of current ORD rates.

1. Compare off-site lots before defaulting to Lot G. Super 8 at about $11/day is about 34% cheaper than Lot G but has no shuttle, so add an Uber or Lyft. For a 7-day trip, that's about a $38 difference. Crowne Plaza at about $13/day includes a shuttle from 5 AM to 9:30 PM.
2. Pre-book during peak periods. Lot G has no advance booking, but off-site lots do. Booking 2-3 weeks before Thanksgiving or Christmas can save you from paying Lot F's $30/day when Lot G is full.
3. Use the ATS strategically. If you park in Lot G and fly from Terminal 5, allow an extra 5-10 minutes for the ATS to loop through all stops. Don't underestimate the transit time when planning your airport arrival.
4. Get TSA PreCheck or CLEAR. The time you save at security more than compensates for the ATS shuttle time from Lot G. TSA PreCheck lets you breeze through a dedicated lane, so budget travelers in economy lots can still move fast through the airport.
5. Avoid Lot G for short trips. If you're only at the airport for 2-3 hours, pay the hourly garage rate; it works out cheaper than the $16 daily cap for quick trips.
6. Check availability on travel day mornings. The O'Hare airport parking status page shows real-time lot availability. Verify Lot G has space before you commit to driving there during busy periods.

Is O'Hare Economy Lot G Safe for Overnight and Long-Term Parking?

Lot G is an official, CDA-operated facility on airport grounds — it is generally safe for overnight and extended stays. The lot benefits from the same security infrastructure as all O'Hare parking areas. Here's what you should know:

• Airport security presence: O'Hare's on-site security patrols extend to the economy lots. The lots are lit at night.
• Open-air exposure: Because Lot G is uncovered, your vehicle is exposed to Chicago's weather. In winter, expect snow accumulation. Budget extra time to clear your car on return during December through March.
• No attendant booth: Unlike some off-site lots that have 24/7 on-site staff, the economy lots rely on automated payment systems and roving security patrols rather than a staffed booth at the lot itself.
• 24-hour access: the Lot G shuttle bus and the ATS run 24 hours, so you can reach your car at any hour. There's no "closed" period for Lot G.
• EV charging: covered Economy Lot F ($30/day) has 24 EV chargers. If you want EV charging at a lower price, Super 8 Chicago O'Hare Airport (off-site, about $11/day) lists EV charging stations on-site.

For multi-week trips, weather protection matters more. If you want covered parking, Economy Lot F at $30/day is the covered on-airport choice. Among the off-site lots on Triply, Routes Airport Parking (about $16/day) is a valet lot, and Pride Airport Parking (about $15/day) adds free baggage help and an on-site car wash.

Final Thoughts on O'Hare Airport Parking Economy G

O'Hare airport parking Economy G delivers solid value at $16/day, tied with Lot H for the cheapest rate on airport property, with a shuttle bus to the free ATS; buses and trains run every 5-10 minutes to all four terminals, 24 hours. For a 5-day trip, you'll pay $80 total. That's about 63% less than the terminal garages and still on official airport grounds.

The main downsides are the lack of advance booking and the open-air exposure to weather. During busy travel periods, the lot fills up. If you want a guaranteed space at a lower price, Super 8 (about $11/day, no shuttle) and Crowne Plaza (about $13/day, shuttle 5 AM to 9:30 PM) cost less than Lot G.
