Which Terminal?
There are currently four terminals at ORD International Airport, which are divided into a further nine lettered concourses. These are organized by international flights arriving at Terminal 5 and departing from Terminals 1 and 3, whilst all domestic flights are spread around the central Terminals 1, 2 and 3.
O'Hare Airport hotel and parking
Many hotels within a 10-mile radius of Chicago O'Hare offer the option to combine airport parking with a hotel stay.
Whilst packages vary from hotel to hotel, many offer up to two weeks of free parking so long as you stay at least one night in the hotel. What’s more, they all provide a regular shuttle bus service to the airport with journey times varying from a few minutes to half an hour; some are less than two miles away, while others are just over 10 miles from the airport.
There are several options ranging from budget motels to luxury hotels at O’Hare, so there’s something for each type of traveler. It's a perfect combination if you don't want a long journey to the airport on the same day you have a long flight.
Useful tips
Beware the Chicago weather
Chicago Airport flight delays are one of the most common causes of complaints about overcrowding in the terminals and customer service. Unfortunately, due to Chicago's unpredictable weather, delays will always be a problem at O'Hare, even with the substantial investment into reducing them with added space.
Whilst there is plenty to do at the airport and, indeed, mere minutes away in the center of Chicago, be prepared for a wait by bringing along books, tablets and other time-passers, especially if you're traveling with children. Make sure you check ahead for weather and traffic problems when working out your journey to the airport. When the weather's good, most passengers report the airport running exceptionally well, so you might be lucky.
Get around the airport quickly and for free
The quickest way to get around the airport from terminal to terminal is usually via the Airport Transit System (ATS), which is a 24-hour rail system that makes the whole airport more accessible without costing passengers another dime.
Look out for short check-in lines
Many regular travelers note that the security check-ins at the ends of the terminals (especially the far-right checkpoints in each terminal) are almost always the least crowded and, moreover, are generally at their longest in the mornings. However, evening flights are more likely to suffer delays than morning flights largely due to the unpredictable weather.
Relax in the airport lounges
Few travelers realize that many of the airline and airport lounges offer a day membership fee, so if you have an unexpected delay or you want to wind down with a range of complimentary snacks, drinks and amenities like showers, it's worth checking them out.
Ask if you're lost
A lot of people complain that customer service at O'Hare can be surly and rude, but this tends to be a result of delays and overcrowding. Passengers traveling through at quieter times report that whilst the customer service approach could use a little polishing, staff almost always give out accurate and helpful information.
Research your connection details
As with some other major international airports, connecting flights, even with the same carrier, can arrive and depart from different terminals, which may be some distance from each other. The ATS and various walkways and tunnels will get you around quickly, but make sure you leave plenty of time between landing and take-off times if you are connecting through O'Hare because it’s a very busy airport.
