O'Hare Airport Lot B: 2026 Rates, Location & Parking Tips

Back to ORD Airport Parking: The Complete O'Hare Guide 2026

O'Hare Airport Lot B is the multi-level parking garage attached directly to Terminal 1 at Chicago O'Hare International Airport, serving United Airlines, United Express, Lufthansa, and All Nippon Airways (ANA) travelers. O Hare airport Lot B is part of the Main Garage complex managed by the Chicago Department of Aviation (CDA), with a daily maximum rate of $43/day (verified June 2026). It is the closest and most convenient on-airport option for Terminal 1 passengers — but it costs significantly more than the economy lots located further from the terminals.

• Location: Lot B is the Terminal 1 parking garage, directly connected to Concourses B and C at ORD.
• Daily rate: $43/day maximum — the same as all Main Garage lots at O'Hare (verified June 2026).
• Hourly rates: $3 for the first hour, $6 for 2 hours, $10 for 3 hours, $14 for 4 hours.
• Best for: Short trips, Terminal 1 flyers (United, Lufthansa, ANA), and business travelers who need direct terminal access.
• Cheaper alternative: Economy Lot G caps at $15/day — saving you up to 65% vs Lot B. Off-site lots start at just $8.95/day.
• ATS access: The free Airport Transit System (ATS) connects all terminals if you park in a different lot.

What Is O'Hare Airport Lot B and Where Is It Located?

Lot B is the parking garage directly attached to Terminal 1 at O'Hare International Airport. It sits immediately adjacent to Concourses B and C — the home of United Airlines, the dominant carrier at ORD.

Physically, Lot B is a multi-level covered structure connected to Terminal 1 via a pedestrian walkway. You can walk from your parking space to the Terminal 1 check-in hall in roughly 5 to 10 minutes, depending on your floor level. No shuttle is needed for Terminal 1 travelers parking in Lot B — that is its main advantage.

To reach Lot B, take I-190 West (the direct airport access spur off I-90/94) and follow signs for Terminal 1 / Departures. The entrance to the Terminal 1 garage is clearly marked along Bessie Coleman Drive. If you're coming from I-294, merge onto I-190 East toward the airport, then follow overhead signs to Terminal 1. During 2026, active construction on the new Concourse D ($1.3 billion project, groundbreaking August 2025) may cause minor signage changes near Terminal 1 — allow a few extra minutes and follow posted detour signs.

How Much Does Parking in O'Hare Lot B Cost? (Full Rate Breakdown)

O'Hare airport Lot B uses the same rate structure as all Main Garage lots, set by the Chicago Department of Aviation. Rates are identical across the Terminal 1, 2, 3, and 5 garages (verified June 2026).

Based on current rates published by the Chicago Department of Aviation, a one-week trip costs $301 in Lot B versus just $105 in Lot G — a difference of nearly $200. For long trips, that gap becomes very difficult to justify. Even Economy Lot F (covered, $22/day) saves you nearly $150 over a week compared to Lot B.

For a broader look at how all on-airport and off-site rates stack up, our O'Hare Airport Parking Rates & Cost Guide 2026 covers every option in detail.

How Do You Get from Lot B to O'Hare Terminals 1, 2, and 3?

Terminal 1 is a direct walk from Lot B — no shuttle required. A covered pedestrian connection links the garage to the terminal building. Expect a 5 to 10 minute walk from most parking levels to the check-in counters.

For Terminal 2 (United Express, Air Canada, JetBlue) and Terminal 3 (American Airlines and its partners), you have two options. You can walk between terminals via the underground pedestrian tunnel that connects Terminals 1, 2, and 3. The walk from Terminal 1 to Terminal 2 takes roughly 10 minutes. Alternatively, take the free ATS (Airport Transit System) — the automated people mover that runs every 3 to 5 minutes, 24 hours a day. The ATS station inside Terminal 1 provides access to all terminals and the economy lots. For Terminal 5 (Delta, Southwest, international carriers), the ATS is your fastest option.

If you are dropping someone off rather than parking, use the Kiss 'n' Fly lot or the designated departure level drop-off zones along Bessie Coleman Drive — these are free for short stops. The Cell Phone Lot at 560 North Bessie Coleman Drive is free and ideal for waiting until your party lands.

How Does Lot B Compare to Lot C and the Main Garage?

Lot B serves Terminal 1, Lot C serves Terminal 2, and both are part of the same Main Garage complex — so their rates are identical at $43/day. The key difference is which terminal they connect to directly.

• Lot B (Terminal 1 Garage): Best for United Airlines, Lufthansa, ANA passengers. Direct walk to Concourses B and C. No shuttle needed.
• Lot C (Terminal 2 Garage): Best for United Express, Air Canada, and JetBlue passengers. Direct connection to Terminal 2. Same daily rate as Lot B.
• Terminal 3 Garage: Best for American Airlines, Alaska Airlines, British Airways, Japan Airlines, and Oneworld partners. Same $43/day rate.
• Terminal 5 Garage: Best for Delta, Southwest, Frontier, Spirit, and international carriers. Same $43/day rate.

From a cost standpoint, there is no financial reason to choose Lot B over Lot C — only proximity to your terminal matters. If you are flying United, park in Lot B. If you are flying JetBlue or Air Canada, Lot C saves you the extra walk. Both cost the same.

The real comparison worth making is Lot B vs. the economy lots. Lot G caps at $15/day — that is a 65% savings compared to Lot B. The trade-off is a short ride on the free ATS. For trips longer than two days, that trade-off almost always favors the economy lot. See our full guide to O'Hare Airport Economy Parking: Lots E, F & G Guide 2026 to compare all three economy options side by side.

What Are the Vehicle Height and Size Restrictions for Lot B?

O'Hare's Main Garage lots, including Lot B, have a standard vehicle clearance limit. Most standard sedans, compact SUVs, and minivans fit without issue. Oversized vehicles — including full-size pickup trucks with bed toppers, large cargo vans, or vehicles with roof racks exceeding typical clearance — may not clear the garage entrance.

If your vehicle is too tall for the covered garage structure, you have solid alternatives at O'Hare:

• Economy Lot G ($15/day): Open-air surface lot — no height restriction.
• Economy Lot E ($17/day): Open-air surface lot — no height restriction.
• Off-site lots like Park 'N Jet ($8.95/day): Open outdoor surface parking, no overhead clearance limits.

Before driving to Lot B in an oversized vehicle, check the posted clearance signage at the I-190 approach to Terminal 1. If there is any doubt, head directly to Economy Lot G or an off-site lot rather than risk getting stuck at the garage entrance during a busy departure push.

How Do You Pay for Parking When Leaving Lot B?

O'Hare's parking garages, including Lot B, accept multiple payment methods at exit lanes. Based on official airport data, accepted payment options include cash, Visa, Mastercard, American Express, Discover, Apple Pay, and Google Pay. Tap-to-pay and contactless payments work at the automated exit kiosks.

You can also pre-pay online via platforms like SpotHero or through flychicago.com to lock in your space in advance. Pre-paying is especially useful around major holidays — O'Hare's ~18,000-space garage and economy lot system can fill quickly during Thanksgiving, Fourth of July, and spring break weekends.

If Lot B is full when you arrive, electronic signs on the approach roads will direct you to the next available garage. Lots C, the Terminal 3 Garage, or the economy lots are all accessible via Bessie Coleman Drive. The ATS makes any of those alternatives workable — rides between any lot and Terminal 1 take just a few minutes.

Planning a trip with TSA PreCheck can also change how early you need to arrive — shorter security lines mean less urgency to park close to your terminal, making economy lots an even smarter choice.

Is Lot B the Best Option for Your Trip, or Should You Choose Economy Parking?

O Hare airport Lot B makes the most sense for short trips and business travelers who value a direct, covered walk to Terminal 1. For stays of three days or more, the economy lots and off-site options offer much better value.

Here is a quick framework for choosing:

• Flying same-day and returning same-day (under 8 hours): Lot B's hourly rates ($3–$14) are competitive. The convenience is worth it.
• 1–2 night trip, flying United from Terminal 1: Lot B at $43/day is convenient but pricey at $86 total. Economy Lot G at $30 total is worth the short ATS ride.
• 3+ night trip: Off-site parking wins. Park 'N Jet at $8.95/day costs roughly $62 for a week vs. $301 at Lot B — a saving of over $238.
• Flying Lufthansa, ANA, or United internationally: Lot B is fine for the night before. Book an off-site lot for the full trip duration.
• Oversized vehicle or truck: Skip Lot B entirely. Use Economy Lot G or an open-air off-site lot.

Travelers frequently report that the ATS people mover is fast enough that the economy lots feel nearly as convenient as Lot B — especially since the ATS runs every 3 to 5 minutes around the clock. The extra 10 minutes of transit time rarely justifies paying nearly three times as much per day.
