Understand ORD and MDW
O’Hare handles most intercontinental services and a large connecting network. Midway is closer to some city areas but generally has fewer long-haul options.
Confirm the airport on every sector; an itinerary that changes Chicago airports is not a normal airside connection.
Flight planning
Chicago as a US connection point
International arrivals connecting domestically should allow time for immigration, customs, baggage procedures and terminal movement.
Compare protected connections on one ticket with separate bookings that leave the traveller responsible for the transfer.
Flight planning
Weather and schedule resilience
Chicago weather can affect operations in winter and during storms. Avoid promises about punctuality and review the provider’s disruption support.
A slightly longer connection may be more workable than the minimum permitted time for an unfamiliar airport.
