The right side wins on cruise variety, with distant views of the southern Rocky Mountain foothills, the red-rock canyon country of southern Utah near Lake Powell and Zion, and then the iconic Las Vegas Strip lined up on final approach. The left side offers a solid Blue Ridge takeoff and a possible Lake Mead glimpse, but overall has fewer standout moments.

Takeoff from IAD
LEFTClimbing out westbound from Dulles, the left side faces south across the Piedmont toward the layered ridgelines of the Blue Ridge Mountains and the Shenandoah Valley, the first real relief after the flat Northern Virginia suburbs. The right side mostly shows flatter farmland toward Maryland with less definition.

Landing at LAS
RIGHTArriving from the east, flights descend into Las Vegas and typically land westbound on runway 26, which puts the Strip's hotel towers just off the nose on the right side during final approach. The Spring Mountains rise beyond the valley as a dramatic backdrop, something the left side, facing mostly open desert, doesn't get.
