Sydney to Dallas — one of the longest passenger flights by distance.
Qantas QF7 flies the tropical convective route from Sydney to Dallas-Fort Worth. Conditions change hour to hour — view the live forecast for your departure date.
View live forecastThis is a short or low-latitude sector, so clear-air turbulence from upper-level jets is rare. 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. A large portion of the flight crosses open ocean (South Pacific), where upper-level conditions are generally smoother than over continental terrain.
Calmest season: Dry season. Transpacific routes are most turbulent in winter months when the polar jet is strong and positioned further south. Tropical routes see more convective (thunderstorm-driven) turbulence during regional wet seasons and monsoon cycles, typically worst in the afternoon and evening.
Full SYD to DFW route guideQantas QF7 operates between SYD and DFW. 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.
QF7 is typically operated by the B789. Aircraft swaps happen — confirm with your booking before flying.
Approximately 16h 33m direct, covering 13,808 km at a typical cruise of FL410.
Historically calmest during Dry season. Forecast accuracy improves as you get closer to departure — within 48 hours the NOAA WAFS model is at peak skill.
