LATAM LA800 flies the mountain-wave sensitive route from Santiago to London. Conditions change hour to hour — view the live forecast for your departure date.
View live forecastThe 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: May–September. The North Atlantic track sees its strongest jet-stream activity from November through February, when winds commonly exceed 150 kt and clear-air turbulence is more frequent. Transpacific routes are most turbulent in winter months when the polar jet is strong and positioned further south. Wind flowing over Andes can generate mountain-wave turbulence that extends hundreds of kilometres downwind — most pronounced in winter when upper-level winds are strongest.
Full SCL to LHR route guideLATAM 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.
LA800 is typically operated by the B789. Aircraft swaps happen — confirm with your booking before flying.
Approximately 14h 03m direct, covering 11,653 km at a typical cruise of FL410.
Historically calmest during May–September. Forecast accuracy improves as you get closer to departure — within 48 hours the NOAA WAFS model is at peak skill.
