Delays, cancellations and missed connections

What to do when a flight at ORD goes wrong: a cancellation late in the day, a delay that eats a connection, or weather that puts a trip at risk. The guides set out your options in the order you need them, what the airline owes you and where to wait.

• Flight canceled at O'Hare: your next steps

  Rebook with your airline. O'Hare's map pins American, Air Canada and United desks past security. Hotel shuttles and terminal transfers are covered too.

  • Start with your airline’s own channels
  • Get online and charge up while you rebook
  • Information desks can point you and help in a crisis
  • A hotel with a shuttle
  • If your new flight leaves from another terminal
• Missed your connection at O'Hare: what to do

  O'Hare lists no rebooking rules. Airline desks, Travelers Aid, the Hilton inside the airport and the way to another terminal.

  • What the airport says about rebooking
  • Information desks and Travelers Aid
  • Which terminal your next airline uses
  • If your next flight leaves from another terminal
  • If the rebooked flight is tomorrow
• Running late for your flight at O'Hare

  O'Hare publishes no check-in or bag cutoff, only checkpoint hours, so your airline's rule decides. What to do at the curb, the checkpoint and the desk.

  • Check your airline’s terminal before you reach the curb
  • The checkpoint lists hours, not wait times
  • What the airport can and can’t tell you about your flight
• What to do when the O'Hare terminal train isn't running

  The airport names no replacement when the train stops. Terminals 1, 2 and 3 connect on foot, and a bus reaches Terminal 5 from 11:30 a.m. to 9:30 p.m.

  • Terminals 1, 2 and 3: walk on the secure side
  • Terminal 5 by bus: who can ride
  • Terminal 5 outside the bus hours
