How early should you leave for Chicago O'Hare International Airport (ORD)?
Getting to Chicago O'Hare International Airport on time isn't about a single magic number — it's the sum of everything between your front door and the gate. Gate Time works backward from your boarding time and subtracts each step: the drive to ORD, parking or curbside drop-off, bag check, check-in, security, and the walk to your gate — then adds any personal buffer you want.
The result is a single, honest leave-by time for your trip out of Chicago, the United States, plus a countdown and downloadable calendar reminders so you're never the person sprinting through the terminal.
Domestic vs. international from ORD
Flying internationally usually means earlier — extra check-in and customs time, and longer security. In Gate Time, flip the flight type to International and it adds that time automatically. Have TSA PreCheck or Global Entry? Toggle it on and your security estimate drops. Checking a bag adds bag-drop time to the plan.

Chicago O'Hare International Airport (ORD) timing FAQ
How early should I get to Chicago O'Hare International Airport (ORD)?
A common rule of thumb is about 2 hours before a domestic departure and 3 hours before an international one. But the right answer depends on your drive, parking, whether you're checking a bag, and the security line — Gate Time turns those into a precise leave-by time for your specific trip.
How does Gate Time calculate when to leave for ORD?
It works backward from your boarding time, subtracting the time you need to get to the gate, clear security, drop bags, check in, park, and drive — plus any personal buffer you add — to give you a single leave-by time.
What if I have TSA PreCheck or am checking a bag?
Toggle TSA PreCheck / Global Entry and Gate Time trims its security estimate; switch on "checking a bag" and it adds bag-drop time. International flights add check-in and customs time automatically.
