Turbulence on the SCL → LHR route

The route crosses mid-latitudes where the polar jet can influence flight conditions, though exposure is shorter than on genuine long-haul crossings. The route crosses or passes near the Andes, 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.

Calmest season: Dry season. The oceanic track sees its strongest jet-stream activity in the relevant hemisphere’s winter, when winds aloft are fastest and clear-air turbulence is more frequent. This corridor is most turbulent in the relevant hemisphere’s winter, when the jet stream is strongest and sits closer to the route. Wind flowing over the Andes can generate mountain-wave turbulence that extends hundreds of kilometres downwind - most pronounced in the relevant hemisphere’s winter, when upper-level winds are strongest. At tropical latitudes, convective (thunderstorm-driven) turbulence dominates during regional wet seasons and monsoon cycles, typically worst in the afternoon and evening.

Frequently asked questions

Is LA800 usually a bumpy flight?

LATAM LA800 operates between SCL 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.

What aircraft does LA800 use?

LA800 is typically operated by the B789. Aircraft swaps happen - confirm with your booking before flying.

How long is the SCL to LHR flight?

Approximately 14h 03m direct, covering 11,653 km at a typical cruise of FL410.

When does LA800 have the smoothest weather?

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.
