While the Boise departure offers immediate mountain drama, the Sydney landing is significantly more visually distinctive and memorable. Sydney Harbour, the Blue Mountains, and the Illawarra coastline provide far greater landmark density and variety than the relatively modest Boise Foothills. The 13+ hour flight is dominated by open Pacific Ocean on both sides, but the right side's landing approach compensates with world-class urban and coastal scenery that elevates the overall score.
