Pro Tips
- The CTA Blue Line is the best bet for downtown — it runs 24/7 and avoids the notoriously congested I-90/94 corridor.
- Connections between Terminal 3 and Terminal 5 (International) require exiting security and re-clearing — leave at least 90 minutes.
- O'Hare is a hub for both United and American, so delays cascade — check flight status aggressively during winter months.
- The Amex Centurion Lounge in Terminal 3 is one of the best in the US network; go early as it fills quickly on busy mornings.
- Ground floor buses and car rental shuttles can be confusing — follow the blue 'Ground Transportation' signs to the central pickup island.
- The new O'Hare Global Terminal is under construction; watch for terminal changes if flying 2025 or later.
- Request early boarding if you're connecting from Terminal 5 — the shuttle bus between T5 and the main terminals takes 15–20 minutes.
