What should I do first if I miss my connection at O'Hare?

Open your airline's app immediately and check your rebooking or start a new one — United and American both auto-rebook at ORD, but rarely onto the fastest flight. Do it before you leave the jet bridge and call the airline at the same time while you head to your gate.

How do I get between terminals at ORD?

O'Hare's domestic Terminals 1, 2, and 3 connect airside, and the Airport Transit System (ATS) plus walkways link them and Terminal 5 for international flights. Check your rebooked gate first — your next flight may be in the same terminal bank, no service desk needed.

Can I be rebooked on another airline at Chicago O'Hare?

Often yes. If your airline's next ORD flight is full or far out, ask to be endorsed to a partner carrier or rerouted through another hub. As a double hub, O'Hare usually has onward alternatives — and Midway (MDW) is a fallback for a fresh ticket if you're truly stuck.

Chicago O'Hare (ORD)

Missed your connection at Chicago O'Hare?

O'Hare is a double hub — United and American both connect huge banks of flights here — so a missed connection at ORD usually has more onward options than you'd expect, but also more travelers racing for them. Weather-driven misconnects are common, and the fastest recovery goes to whoever rebooks in the app while walking and reaches the desk with a specific flight in mind. Here's what to do the moment you miss your connection at O'Hare.

1. Rebook in the app the moment you land

The instant you know you've missed the connection, open your airline's app and check your rebooking or start a new one. At ORD, United (Terminals 1 and 2) and American (Terminal 3) both auto-rebook — but rarely onto the fastest flight. Start before you reach the concourse; the app beats the desk line almost every time.

2. Know your terminal and use the ATS/walkways

O'Hare's domestic terminals (1, 2, 3) connect airside, and the Airport Transit System (ATS) plus pedestrian tunnels move you between them and Terminal 5 (international). Check your rebooked gate first — if your next flight is in the same terminal bank, you may not need a service desk at all.

3. Call the airline while you walk

Dial your airline or use the app's chat/callback at the same time you're moving. Whichever reaches a solution first wins. At a hub this busy, phone agents can sometimes grab seats faster than the crowded in-terminal desks. Ask for a specific next flight rather than an open search.

4. Ask about partner airlines and other Chicago options

If your airline's next ORD departure is full or hours away, ask to be endorsed to a partner carrier or rerouted through another hub — and don't forget Chicago Midway (MDW) exists for a fresh ticket if you're truly stuck. Say directly: 'Can you put me on a partner or another airline tonight?'

5. Know what you're owed if you're stuck overnight

If the misconnect was the airline's fault (a controllable late inbound) and you're stranded at O'Hare overnight, ask for a hotel, meals, and transport. On covered international itineraries you may also be owed cash compensation. Rebooking and compensation are separate — pursue both and keep receipts.
