The Perth-London Dreamliner — Qantas's nonstop Australia-Europe service.
Qantas QF9 flies the jet-stream + mountain-wave corridor from Perth to London. Conditions change hour to hour — view the live forecast for your departure date.
View live forecastJet-stream exposure on this corridor is significant. Long mid-latitude legs mean clear-air turbulence is the dominant source of bumps, typically encountered at cruise altitude. The route crosses or passes near the Caucasus, which can generate mountain-wave turbulence downwind when upper-level winds are strong. At tropical latitudes, convective turbulence from thunderstorms is the main driver — pilots generally route around storm cells, but afternoon/evening flights encounter more build-up than morning departures. Westbound aircraft typically fly against the prevailing winds, adding flight time. Captains often pick altitudes that avoid the strongest headwinds, which can also mean picking cleaner-air altitudes.
Calmest season: Late spring and early autumn. Wind flowing over Caucasus can generate mountain-wave turbulence that extends hundreds of kilometres downwind — most pronounced in winter when upper-level winds are strongest.
Full PER to LHR route guideQantas QF9 operates between PER and LHR. Whether it’s bumpy depends on the day’s weather — Turbcast pulls live NOAA aviation-grade data so you can check the actual forecast for your departure date rather than relying on averages.
QF9 is typically operated by the B789. Aircraft swaps happen — confirm with your booking before flying.
Approximately 17h 22m direct, covering 14,508 km at a typical cruise of FL410.
Historically calmest during Late spring and early autumn. Forecast accuracy improves as you get closer to departure — within 48 hours the NOAA WAFS model is at peak skill.
