Sit on the Right side of the plane for the best views on flights from Toronto to Mexico City. While left side wins at takeoff for the Toronto skyline, right side delivers the more dramatic and sustained views: the Gulf of Mexico coastline visible mid-flight, and the spectacular volcanic peaks of Popocatépetl and Iztaccíhuatl on descent into Mexico City. The volcanic approach alone makes right side the better overall choice.

During takeoff from Lester B Pearson International (YYZ), sit on the Left side for the best views. YYZ's primary departure runways (05/23 and 06L/24R) typically send southbound flights climbing out over the city core. A left seat gives you the downtown Toronto skyline including the CN Tower, Lake Ontario's north shore, and the urban grid of Mississauga and Etobicoke falling away below. Right side faces northwest toward suburban sprawl with little of interest. Notable sights include: CN Tower and downtown Toronto skyline, Lake Ontario shoreline, Toronto Islands, Hamilton Harbour visible to the southwest.

When landing at Licenciado Benito Juarez International (MEX), sit on the Right side for the best views. Mexico City's primary arrival runways (05R/23L) typically bring aircraft in from the northeast over the Valley of Mexico. A right seat on approach gives you the best view of the Sierra Nevada volcanic peaks — Popocatépetl and Iztaccíhuatl — rising dramatically to the southeast of the city, plus the sprawling urban basin of CDMX. Left side faces northwest toward less dramatic terrain. Notable sights include: Popocatépetl volcano (5,426m), Iztaccíhuatl volcano (5,230m), the urban basin of Mexico City, Texcoco lakebed (former Lake Texcoco, now dry salt flats east of the city).

The flight from Lester B Pearson International (YYZ) to Licenciado Benito Juarez International (MEX) takes Approximately 4 hours 30 minutes to 5 hours.

The flight tracks southwest over Lake Erie, then crosses Ohio and Kentucky before entering the Gulf coastal plain over Tennessee and Mississippi. Over the Gulf of Mexico the view is open water for roughly 45-60 minutes. The Yucatan Peninsula and southern Mexican highlands are visible on the final hour, with the Sierra Madre Oriental rising to the right as the aircraft descends toward the Valley of Mexico.
