Overview

Perth to London Heathrow — Qantas's non-stop link between Western Australia and the UK, usually flown by 787-9. It is one of the clearest examples of a route where duration hurts more than the time-zone shift.

Jet lag

Perth to London is a westward delay. It is easier than an equivalent eastward advance, but the 17+ hour cabin block still makes the first local evening important: stay up, eat lightly, and get outside.

Estimated recovery

Without intervention ~5 days
With timed light + melatonin ~3 days

Estimates only — based on ~1 day per time zone west, compressed roughly 40% with a timed protocol. See how long jet lag actually lasts .

Best window side

The right side generally gives the better chance of softer northern light as the route tracks northwest toward Europe. If you intend to sleep, choose the side that lets you control glare.

Best · Right

The right window is the calmer pick on this route. For sleep, the window itself matters more than the side — see how to sleep on a long-haul. For the exact rows and seat letters on this aircraft, use the seat picker.

Cabin atmosphere

The 787-9 is better than older wide-bodies for cabin feel, but Perth to London is long enough that dry-air symptoms still accumulate. Hydrate normally and protect your sleep setup early.

Expected cabin humidity at cruise

This route's typical aircraft ~15-20%
Indoor air at home ~40-60%

Composite-fuselage aircraft (787, A350) run higher humidity than older aluminum-fuselage types. See what the 787 actually fixes.
