❓ Frequently Asked Questions
Is O'Hare or Midway better for layovers?
ORD is better for international connections and lounge access. Midway (MDW) is closer to downtown but has fewer international flights.
Can I visit downtown on a 5-hour layover?
Tight but possible with the Blue Line (45 min each way). You'd have about 2 hours in the city. 6+ hours is more comfortable.
Why is it called ORD?
The code comes from the airport's original name: Orchard Field. The name changed to O'Hare in 1949, but the code stuck.
