Car Rental at O'Hare Airport (ORD)
Image
Renting a car at O'Hare gives you the freedom to explore Chicago and its surroundings at your own pace. Most major companies are located in a centralized facility, but the experience can vary drastically from one to another. This guide, based on real experiences, will help you choose the right company and avoid the most common pitfalls.
Quick Questions about Car Rentals at O'Hare
- What is the biggest issue? Hidden charges and unexpected cleaning fees. Companies like Dollar, Thrifty, Avis, and Budget accumulate complaints about charges of hundreds of dollars for supposed odors or damages that appear days after the return.
- Are there long waits? Yes, it is a very common complaint, even with a reservation. Especially at Avis and Budget, travelers report waits of over an hour due to lack of staff or available cars.
- Which are the most reliable? Alamo and National are the most praised for their efficiency (especially with online check-in or the Emerald Aisle) and transparent processes. Enterprise also receives very good reviews for its service.
- Which have the most warnings? Dollar and Thrifty lead in complaints about misleading billing practices. Avis and Budget for long waits and billing issues. It is crucial to document everything with these companies.
- Where are they located? All major companies are located at the Multi-Modal Facility (MMF). You can get there on the free Airport Transit System (ATS) train from any terminal.
- Should I return the car with a full tank? Yes, and do it with margin: there are no convenient gas stations near the airport. The recommendation from several travelers is to fill the tank about 15-20 miles before returning the car, since even when doing so, some report incorrect fuel charges.
What No One Tells You Before Renting at O'Hare
Hidden Charges: The Number One Problem
User experience:
The most repeated pattern in reviews, regardless of the company, is the charge that appears days after the return: cleaning fees for supposed odors, insurance marked as accepted when the customer verbally declined it, or fuel charges despite having returned the tank full. One documented case describes a final price that went from 250 to 550 dollars (a 120% increase) for coverages added without explicit consent. The rule that repeats in almost all reviews: when you decline insurance or extras verbally, it's a good idea to ask for it to be recorded in writing or in the system, because otherwise it may end up marked as accepted.
Strategy: photograph and film the car inside and out before leaving the lot, including the fuel level and odometer, and keep a copy of the signed contract with the insurance you actually accepted.
The Waits, Even with a Confirmed Reservation
User experience:
Having a reservation does not guarantee that the car will be available upon arrival. System failures have been documented that generate waits of over an hour, reserved cars that end up assigned to another customer, and even a case of a traveler stranded at 1am with no vehicle available and no one informing them in advance. The problem is especially concentrated at Avis and Budget during peak demand hours.
Strategy: if your flight arrives late at night or during peak demand hours, confirm your reservation by phone or app on the same day, and have a backup plan (another company or a private transfer) in case the counter has no cars.
Fuel and Tolls: What No One Warns You About
User experience:
Two logistical details generate more conflict than they seem. First, there are no convenient gas stations near the airport — several travelers mention it as an unpleasant surprise just before returning the car. Second, Illinois' toll system (I-PASS) automatically charges when passing through a toll, even if you haven't purchased the rental company's toll package — which can result in high charges for tolls of just a few dollars if the company applies its own processing fee.
Strategy: fill the tank 15-20 miles before arriving at the airport, and if you're going to use toll highways, decide upfront whether to purchase the company's package or bring your own transponder — don't leave it unresolved.
The Human Factor: Staff Can Change Everything
User experience:
A pattern across almost all companies: even in the worst experiences, there are specific employees that reviews highlight for genuinely attentive service that completely changes the customer's perception — from managers who calmly resolve double billing to staff who go above and beyond to return forgotten items or resolve a customer's personal emergency. The quality of service at O'Hare depends, to a large extent, on who you happen to interact with that day.
A key tip: The biggest risk when renting a car at O'Hare is arriving to find very high rates or a lack of vehicles, especially during high season. To avoid surprises and secure not only a better price but also the availability of the car you need, it is highly recommended to book in advance.
Location and How to Get to the Rental Center
O'Hare's Multi-Modal Facility (MMF) houses a centralized car rental center where the main companies operate. To get there, you need to take the automated train, known as the Airport Transit System (ATS) or People Mover.
This free train provides a smooth connection not only between the MMF and all terminals, but also to the F parking lots, the Kiss 'n' Fly area, and the bus station. Although the system is generally efficient, keep in mind that during peak hours trains can be full and you may experience some waiting time. Also note that once at the MMF, the walk from the ATS station to your company's pickup lot can be considerable — something to consider if you're traveling with limited mobility or a lot of luggage.

Rental Companies at the Airport (Multi-Modal Facility)
The rental experience varies enormously between companies. Below is a summary based on the most recent reviews.
Alamo
User experience:
Consistently one of the highest rated. Travelers praise the speed and efficiency of the pickup and return process, often thanks to the online check-in option (Skip the Counter) that allows you to bypass the lines entirely — several describe arriving at the lot and leaving in minutes without talking to anyone. Staff are described as friendly and professional even in the early hours, and there are cases of flawless roadside assistance for a flat tire. The main recurring warning is toll charges: documented charges of over 28 dollars for an actual toll of just 3, even with GPS set to avoid them.
Strategy: if Alamo charges you a toll that seems disproportionate, ask for the exact breakdown — several travelers managed to get it reviewed by claiming with the details in hand.
alamo.com - Hours: 24 hours
National
User experience:
Another favorite, especially among business travelers. The Emerald Aisle program, which allows you to choose your car directly from the parking lot without going through the counter, is the most praised point for its speed and convenience — several travelers describe the entire process, from getting off the ATS to driving out with the car, in about 10 minutes. Service is consistently rated as efficient and hassle-free. Although the selection of cars in the Executive category can vary, staff are usually proactive in solving any issues, and there are cases of credits applied on the spot for billing errors.

Enterprise
User experience:
Generally receives good reviews for its friendly and efficient customer service. The check-in and return process is quick, and many appreciate the option to skip the counter using the app. Vehicle quality is a strong point, and staff are praised for maintaining a professional attitude even in conflict situations, such as double billing errors. The main point of attention is toll costs; the daily pass can be expensive, and the alternative of using the Illinois toll app doesn't always work well for travelers.
Strategy: check your pockets well before leaving the car — there are cases of travelers who left the airport with the keys by mistake, and Enterprise staff went all the way to the security line to return them in time.

Sixt
User experience:
Stands out for its fleet of high-end vehicles and staff often described as exceptional in recent reviews. The online check-in process is very efficient. However, the main recurring warning is about damage charges: several users report being charged for small scratches or pre-existing issues, even when they were able to provide photos and video as evidence. It is crucial to thoroughly inspect the car and document everything before leaving.
Strategy: if Sixt charges you for damage you dispute, request in writing the photographic documentation from before and after your rental — several travelers report that the company doesn't always provide it spontaneously.
sixt.com - Hours: 5:30 am to 12:00 am
Avis
User experience:
Presents a very mixed experience. The most serious criticisms focus on long waits (sometimes over an hour, worsened by system failures) and fraudulent or "mysterious" charges, such as cleaning fees for smoke in non-smoking cars. One documented case describes a reservation for a large vehicle for a special occasion, a 2.5-hour wait due to a system failure, and a forced downgrade under time pressure. Lack of staff during peak hours is a common complaint. On the other hand, some travelers report excellent interactions with specific employees who notably improve the experience. It is essential to review the bill in detail.
avis.com - Hours: 24 hours
Budget
User experience:
As part of the same company as Avis, it shares similar problems. The most frequent complaints are about hidden charges (fuel, unsolicited insurance) and very long waits due to lack of staff. There are reports of no cars being available despite having a reservation. However, there are also positive mentions of management staff who resolve difficult situations with empathy and effectiveness, even in the face of customer personal emergencies. The recommendation is the same: document everything and review the charges.
budget.com - Hours: 24 hours
Hertz
User experience:
The experience is very variable. Online check-in is a plus for avoiding lines. However, there is a pattern of complaints about subsequent charges for pre-existing damage and cleaning fees for smoke that customers deny. Even loyalty program members report that the benefit of skipping the counter frequently fails, forcing them to wait in line like any customer — in one case, after 20 hours of travel. Fleet quality in loyalty categories sometimes disappoints. Some users also report that customer service to resolve these issues can be a long and frustrating process.
Strategy: if you are a Gold or Presidential Circle member, don't take for granted that you'll skip the counter — confirm your reservation status before arriving, especially on flights that land very early or very late.
hertz.com - Hours: 5:00 am to 12:00 am
Dollar
User experience:
It is one of the companies with the most warnings. The main problem is the business model based on unexpected charges and cleaning fees of 400 dollars that appear on the bill days after the return. A documented and very repeated pattern: insurance added to the contract despite being verbally declined at the counter. Long waits (over an hour) to pick up the car are common. Although some customers report friendly treatment at the counter and even almost new cars as a positive surprise, the pattern of subsequent charges for supposed odors or dirt is too frequent to ignore.
dollar.com - Hours: 6:00 am to 12:00 am
Thrifty
User experience:
Similar to Dollar, it suffers from a pattern of opaque billing practices. Travelers complain that insurance or toll passes are added that they explicitly declined. Long lines and lack of staff are also a recurring problem, as well as cases of cars that don't match the reserved category without compensation, or with tires in poor condition detected only after leaving the airport. Although good rates can be found, the risk of ending up paying much more than budgeted is high.
Strategy: before leaving the lot, check all four tires and confirm that the car model matches what was reserved — if not, ask for compensation on the spot, not later.
thrifty.com - Hours: 6:00 am to 12:00 am
Fox
User experience:
Offers competitive prices, but the experience is a gamble. Many travelers complain about hidden and misleading charges, especially with the toll pass and fuel price per gallon, and there are cases of damage charges applied despite having a policy and video evidence. Waits can be very long due to lack of staff, and some vehicles exceed 60,000 miles in poor condition. However, there is also a significant number of reviews praising the friendliness and professionalism of specific employees, who often save the experience — including a case of forgotten keys recovered two weeks later.
foxrentacar.com - Hours: 5:30 am to 12:00 am
Payless
User experience:
Reviews are mixed. Service can be very fast if there is no line. However, there are recurring complaints about unauthorized charges (such as fuel prepayment) and customer service that is not very effective at resolving these errors. Lack of staff at key moments is a problem, with reports of empty counters and vehicles delivered with tires in poor condition. Despite this, there are reviews that highlight specific employees for going the extra mile to help customers, even holding long lines alone without a break.

Rental Companies Outside the Airport
These companies usually offer more competitive rates, but require taking a shuttle bus from outside the terminals to their facilities.
User experience:
The general pattern for companies outside the airport is a trade-off: potentially lower prices in exchange for more time and possible complications. Common complaints include long waits for the shuttle, lack of transparency in final charges (insurance, tolls), and less agile return processes. However, many travelers choose them for the savings and report positive experiences when everything goes smoothly.
REMEMBER:
Booking your rental car in advance is key to avoiding long waits and securing a cheaper rate. Many passengers also recommend carefully reviewing the terms and conditions, especially if traveling outside the state of Illinois, as additional fees may apply. Returning the car with a full tank is recommended, as several users reported unexpected fuel charges despite having filled the tank before return.
Pros and cons of car rentals at O'Hare
Pros: unified center (MMF) with direct access via the free ATS train; Alamo, National, and Enterprise offer agile processes with online check-in or Emerald Aisle; companies outside the airport with more economical rates; employees who in many cases resolve problems with excellence.
Cons: hidden charges and cleaning fees that appear days later, especially at Dollar, Thrifty, Avis, and Budget; waits of over an hour even with a confirmed reservation; absence of gas stations near the airport; I-PASS toll charges that may apply even if you haven't purchased the company's package; considerable walk from the ATS to the pickup lot.
