Route overview

Los Angeles International Airport (LAX) in Los Angeles, the United States, to Miami International Airport (MIA) in Miami, the United States, is a great-circle distance of 3,763 km, about 2,032 nautical miles. At typical jet cruise speeds, and with an allowance for climb, descent and approach, that works out to roughly 4h 53m of airborne time. The great-circle track leaves Los Angeles eastbound and spends most of the flight in subtropical air.

Leaving Los Angeles

Los Angeles International sits on the Pacific shoreline with the San Gabriel Mountains inland. Departures climb over water into the marine layer, and Santa Ana conditions in autumn add downslope wind from the ranges. The great-circle track leaves LAX eastbound, and the first waypoint band of the flight sits close to 31.9N 108.9W. On a sector of 4h 53m, the climb to cruise takes roughly the first twenty to twenty five minutes.

Mountain wave over the Rockies

The midpoint of the LAX to MIA track lies near 29.9N 99.3W, about 1,882 km from Los Angeles, which is where the corridor spends its longest continuous stretch at cruise level. The track crosses the Rocky Mountains, where westerly wind lifted over the ridge line oscillates downwind and produces mountain wave turbulence at cruise level. On windy days that gives a defined bumpy segment of roughly twenty to thirty minutes, with settled air before and after it.

Cruise altitudes on this sector

Medium haul sectors typically level off between FL330 and FL390, with a single step climb once fuel burn has lightened the aircraft. Choice of level matters because turbulence is layered: a change of two or three thousand feet often puts the aircraft into calmer air, and that is one of the first adjustments a crew will request.

Arriving into Miami

Arrivals into Miami cross the sea breeze boundary that sets up over south Florida most summer afternoons. Crews use radar to pick a clean path through it, and the ride settles quickly once through. Descent normally begins around 27.8N 89.8W, roughly 941 km before MIA, and takes about half an hour from cruise level to touchdown.

Seasonal pattern

Mountain wave activity follows the strength of the winter westerlies, so the most defined wave segments occur between November and March, and mid summer crossings are typically calm.

Flying this route with less worry

Turbulence on this corridor is a comfort issue rather than a safety one. Airliners are certified to handle loads well beyond anything the atmosphere produces here, crews are trained for it, and the seat belt sign is the tool that keeps the cabin settled.
