Sit on the Left side of the plane for the best views on flights from San Francisco to Cancun. Left side wins both ends of the flight. During the cruise over Mexico, the left side also offers occasional views of the Gulf of California coast and the Sierra Madre Occidental in the distance during the early portion of the flight, making it the stronger choice throughout.

During takeoff from San Francisco International (SFO), sit on the Left side for the best views. SFO's primary departure runways (28L/28R) head west over the Bay then turn south. A left seat gives you San Francisco Bay, the city skyline, and the Peninsula as you climb out and bank south. Right side faces the open Pacific with little to see. Notable sights include: San Francisco Bay, downtown SF skyline, San Mateo Bridge, Santa Cruz Mountains.

When landing at Cancun International (CUN), sit on the Left side for the best views. CUN's runway 12/30 typically has arrivals from the northwest, meaning the aircraft approaches over the Yucatan Peninsula and turns over the Caribbean. A left seat gives you the turquoise Caribbean Sea, the hotel zone barrier island, and Cancun Lagoon on final approach. Right side faces inland scrub jungle. Notable sights include: Caribbean Sea turquoise shallows, Cancun Hotel Zone barrier island, Nichupte Lagoon, Isla Mujeres.

The route tracks southeast over the Mojave Desert, crosses the Gulf of California near Guaymas, overflies the Sierra Madre Occidental foothills of northwestern Mexico, then crosses the broad flat plateau of central Mexico before descending over the Yucatan Peninsula's low limestone jungle toward the Caribbean coast.
