Consider a flight that departs Chicago at 1:00 PM and has a scheduled duration of 4 hours 30 minutes:
The scheduled duration can differ between nonstop flights because several operational factors affect the journey:
O’Hare taxi time:
Long taxi routes or departure queues can add time before the aircraft takes off.
Flight path:
Air-traffic control may assign a longer route to avoid congestion, storms or restricted airspace.
Wind conditions:
Headwinds can increase airborne time, while favorable tailwinds may shorten the journey.
Mexico City airport traffic:
The aircraft may need to wait for landing clearance or an available arrival gate.
Airline scheduling:
Each airline may include a different amount of extra time to account for routine operational delays
A nonstop itinerary completes the journey in one flight and is normally the quickest option. A connecting itinerary includes two flight segments and a layover, so there is no single standard duration. The total can change significantly according to the connection point and waiting time.
When comparing itineraries, check the total elapsed time shown in the booking results—not only the duration of each flight segment. Also verify the airport codes. This page uses schedule data specifically for ORD to MEX, so an itinerary involving a different Chicago-area or Mexico City-area airport is not directly comparable.
Aeromexico, American Airlines, United Airlines, Viva and Volaris currently operate nonstop flights between Chicago O’Hare (ORD) and Mexico City (MEX). Flight frequency and availability vary by travel date. Some services may be sold under a partner airline’s flight number, so check the “operated by” details to confirm which airline will operate your flight.
