Can I stay overnight at the airport?

Overnight stays at O'Hare International Airport can be a convenient option for travelers with long layovers or canceled flights. Generally, the airport remains open 24 hours a day, allowing passengers to stay overnight. However, it is important to note that certain areas may close during the night, and access to some amenities, such as shops and dining options, will be limited after regular business hours. Travelers can find seating options in various terminals, but it is advisable to choose a relatively quieter location for a more comfortable experience. Security personnel might occasionally check on individuals who stay overnight, so having identification and boarding passes readily available is a good practice. Additionally, O'Hare offers hotels nearby for those who prefer a more restful environment compared to the airport seating. For more details on amenities that may be available during an overnight stay or for information related to specific terminal operations, it could be beneficial to check the official O'Hare International Airport website.
