Chicago O'Hare has 12 airline lounges across 4 terminals. The United Polaris lounge in Terminal 1 is the best overall with table-service dining and daybeds. The American Airlines Flagship Lounge and Delta Sky Club are strong alternatives. Priority Pass holders are limited to two Terminal 5 options.

Our take

The United Polaris lounge in Terminal 1 Concourse C is the standout lounge at ORD — the table-service dining and private daybeds make it worth arriving early for.
