# Delays, cancellations and missed connections

Every ORD guide on delays, cancellations and missed connections: 4 guides, each answering one question.

Updated October 31, 2026

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.

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.

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

[Running late for your flight at O'Hare](https://ordairportguide.com/guides/running-late-flight-at-ohare/)

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.

[What to do when the O'Hare terminal train isn't running](https://ordairportguide.com/guides/what-do-when-ohare-terminal-train-not-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.
