The right side wins because of the striking Mount Rainier and Cascade views during departure, which outweigh the modest Dallas skyline glimpse on landing; the cruise phase over the Rockies and Great Plains is largely symmetrical and flat on both sides.

Takeoff from SEA
RIGHTDeparting SEA on the southbound runway before turning east toward Dallas, the right side gets a dramatic close-up of Mount Rainier's snowy summit rising above the Cascade foothills, with Puget Sound and the South Sound lowlands falling away below. The left side mostly shows the flatter Kent/Auburn valley and distant Cascade ridgelines with less drama.

Landing at DFW
LEFTOn the north-flow approach into DFW, the descent path passes west of downtown Dallas, so the left side offers a distant but recognizable view of the Dallas skyline across flat farmland before the final turn south to land. The right side faces open plains toward Fort Worth with no comparable landmark.
