Sit on the Right side of the plane for the best views on flights from Phoenix to Liberia. Right side wins overall. The Phoenix departure offers the best urban and mountain scenery on the right, and during the cruise southward over Mexico the right side tracks closer to the Sierra Madre Occidental and the Pacific coast of Mexico, including the Gulf of California early in the flight. The left side is better for the LIR landing, but the departure and mid-flight views on the right are more consistently interesting across the full journey.

During takeoff from Phoenix Sky Harbor International (PHX), sit on the Right side for the best views. PHX primarily uses runways 7R/25L and 8/26. Departing westbound (runway 26), a right-side seat looks south toward South Mountain Park and the Estrella Mountains. Departing eastbound (runway 8), right side faces north toward Camelback Mountain and the McDowell Mountains. Either way, right side captures the more dramatic terrain surrounding the Valley of the Sun. Notable sights include: Camelback Mountain, South Mountain Park, Estrella Mountains, downtown Phoenix grid.

When landing at Daniel Oduber Quiros International (LIR), sit on the Left side for the best views. LIR's runway 07/25 means arrivals typically come in from the east or west over the Guanacaste lowlands. On approach from the north, the left side faces west toward the Gulf of Nicoya and the Pacific coastline of the Nicoya Peninsula, which is the most dramatic scenery on arrival. The volcanic peaks of the Guanacaste Volcanic Chain are also better framed on the left during standard approach patterns. Notable sights include: Nicoya Peninsula coastline, Gulf of Nicoya, Rincón de la Vieja volcano, Miravalles volcano.

The flight from Phoenix Sky Harbor International (PHX) to Daniel Oduber Quiros International (LIR) takes Approximately 4 hours 30 minutes to 5 hours.

The flight tracks south-southeast over the Sonoran Desert into the Mexican state of Sonora, then crosses the Sierra Madre Occidental foothills. Over central Mexico the route passes near Guadalajara and the Trans-Mexican Volcanic Belt, where Popocatépetl and Iztaccíhuatl may be visible on clear days to the east. The flight then crosses the Isthmus of Tehuantepec, the narrow land bridge connecting North and Central America, before entering Guatemala and El Salvador airspace. The Pacific coastal plain of Central America is visible on the right throughout the final hour, with the volcanic chain of Guatemala and El Salvador — including Volcán de Fuego and Santa Ana — appearing as a line of conical peaks along the right horizon.
