Left side wins both ends of the flight. At takeoff you get the full Cancun lagoon and Caribbean reef system, and on approach to Seattle the left side delivers Mount Rainier and the Cascades. During the cruise over the Gulf of Mexico and the US interior, neither side has a decisive advantage, but the bookend views on the left are the most visually distinctive of the entire route.
Flight Path
The route crosses the Gulf of Mexico (featureless open water), makes landfall near the Texas coast around Corpus Christi or Brownsville, then tracks northwest over the Texas Hill Country, New Mexico high desert, and the Colorado Plateau. The Rocky Mountains of Colorado or Utah may be visible depending on exact routing. The Great Basin of Nevada is largely flat and brown. The Sierra Nevada or Cascades appear in the final hour before descent into Seattle.

Phase by phase
Takeoff from CUN
LEFTCancun's runways are oriented roughly east-west (runway 12/30). Departing westbound toward the US, the left (south) side gives you views over the turquoise lagoon system of Nichupte and the hotel zone strip. The Caribbean coastline and barrier reef are clearly visible as a color gradient from pale turquoise to deep blue.
Landing at SEA
LEFTSeattle-Tacoma primarily uses runways oriented north-south (16L/R and 34L/R). On a southerly approach from the north, the left (east) side faces the Cascade Range including Mount Rainier, which dominates the southeastern horizon at over 14,000 feet. The right side faces Puget Sound but Mount Rainier's visual impact from the left is unmatched.
