Sit on the Left side of the plane for the best views on flights from Chicago to Lisbon. While takeoff favors the right for Lake Michigan views, the landing approach over the Tagus estuary and Lisbon's historic center is far more visually rewarding and geographically significant. Left-side seats capture the entire approach sequence with the river, bridges, and city landmarks clearly visible.

During takeoff from Chicago Midway International (MDW), sit on the Right side for the best views. Midway typically departs eastbound (runways 04L/04R or 22L/22R depending on wind). Right-side seats offer views of Lake Michigan's shoreline and the Chicago downtown skyline as you climb out over the lake. Left side faces inland residential areas with less visual interest. Notable sights include: Lake Michigan (immediate right, expanding as you climb), Chicago downtown skyline (visible across the lake to the northeast), Indiana shoreline (distant right), Calumet River industrial area (left, but less dramatic).

When landing at Lisboa (LIS), sit on the Left side for the best views. Approaching Lisbon typically uses runways 03 or 21 depending on wind. Left-side seats on descent offer views of the Tagus River estuary, the city's historic districts on the north bank, and the Atlantic coastline. Right side faces the Setúbal Peninsula and less populated terrain. Notable sights include: Tagus River estuary (dominant feature, wide and distinctive), Lisbon city center on north bank (Baixa district visible as urban grid), 25 de Abril Bridge (red suspension bridge crossing the estuary), Cristo Rei monument on south bank (white statue visible on Caparica side).

The flight from Chicago Midway International (MDW) to Lisboa (LIS) takes Approximately 8.5 to 9.5 hours.

The flight path crosses the Atlantic at roughly 35,000 feet, passing north of Bermuda (not visible at cruise altitude), then over the open ocean with no significant landmarks. As you approach European airspace, the Azores archipelago lies south of the typical routing. The Irish coast (County Cork/Kerry area) becomes visible on the left approximately 1.5 hours before Lisbon arrival. The flight then tracks southeast across the Celtic Sea and Bay of Biscay, with the Iberian Peninsula appearing on the left around 45 minutes before descent, showing the Portuguese coast near Cape Roca and the Sintra mountains inland.
