Getting to ORD without losing your buffer
- O'Hare drive times are affected by the Kennedy Expressway and regional rush-hour traffic. Estimate the route for the day and hour of travel.
- Remote parking and rental-car returns require an additional airport transfer. Do not fold that into an optimistic drive estimate.
- Winter weather can affect both road travel and airport movement, so check conditions and increase the margin when needed.
Inside Chicago O'Hare
