Sit on the Left side of the plane for the best views on flights from Cancun to Chicago. Left side wins both ends of the flight. At departure you get the spectacular Caribbean lagoon and Hotel Zone views, and at arrival you get the Chicago lakefront and downtown skyline. Over the Gulf of Mexico and central US the views are similar on both sides, so the departure and arrival scenery tips it decisively left.

During takeoff from Cancun International (CUN), sit on the Left side for the best views. Cancun's primary departure runway 12/30 means northbound flights typically depart heading northwest on runway 30. A left-side seat gives you the lagoon system and Hotel Zone peninsula as you climb out over the Caribbean side. You get a clear look back at Nichupte Lagoon and the narrow barrier strip of the Hotel Zone before turning north. Notable sights include: Nichupte Lagoon, Cancun Hotel Zone barrier peninsula, Caribbean Sea turquoise shallows, Isla Mujeres offshore to the northeast.

When landing at Chicago Ohare International (ORD), sit on the Left side for the best views. O'Hare arrivals from the south typically use runways 10L/10R or 28L/28R depending on wind. Southbound approaches or those from the southeast put Lake Michigan on the left side, giving you the Chicago lakefront, Grant Park, and the downtown skyline. The left seat consistently delivers the city view on approach regardless of which runway configuration is active. Notable sights include: Chicago downtown skyline and Loop, Lake Michigan shoreline, Grant Park and Museum Campus, O'Hare airport grid visible on final.

The flight from Cancun International (CUN) to Chicago Ohare International (ORD) takes Approximately 3 hours 30 minutes to 3 hours 50 minutes.

After departing Cancun the route crosses the Yucatan Peninsula briefly, then tracks north-northwest over the Gulf of Mexico for a long overwater segment. The Mississippi River delta and Louisiana coastline appear as the flight re-enters the US, followed by the flat agricultural plains of Mississippi, Tennessee, and Kentucky. The Ohio River valley marks the transition into the Midwest, and the flat Illinois corn and soybean grid dominates the final hour before Chicago.
