Sit on the Right side of the plane for the best views on flights from Sydney to Houston. The Sydney departure on the right side delivers one of the world's great urban aerial views — Sydney Harbour, the Opera House, and the CBD in a single sweep. The Houston arrival is relatively flat and unremarkable on either side. The right side wins on the strength of the Sydney departure alone.

This is one of the most iconic urban departure views in aviation. Notable sights include: Sydney Harbour and Harbour Bridge, Sydney Opera House, CBD skyline including Centrepoint Tower, Botany Bay directly below on climb-out.

On a southerly approach to runway 15L or 33R, the left side faces east toward downtown Houston, giving clear views of the Houston skyline and the flat Gulf Coastal Plain. The right side faces west into suburban sprawl with no distinctive features. Notable sights include: Houston downtown skyline, Lake Houston to the northeast, the flat Gulf Coastal Plain grid of suburban Houston, Buffalo Bayou corridor.

The route crosses the Tasman Sea, then the vast expanse of the South Pacific Ocean for many hours with no land visible. The flight passes north of New Zealand's South Island (visible distantly on some routings), crosses the equatorial Pacific, passes over or near the Hawaiian Islands chain depending on routing, then crosses the North Pacific before descending over the Gulf of Mexico coastal plain into Houston. The dominant mid-flight feature is simply the immense blue emptiness of the Pacific, with occasional cloud systems and the International Date Line crossing.
