Route overview

Hartsfield Jackson Atlanta International Airport (ATL) in Atlanta, the United States, to Los Angeles International Airport (LAX) in Los Angeles, the United States, is a great-circle distance of 3,126 km, about 1,688 nautical miles. At typical jet cruise speeds, and with an allowance for climb, descent and approach, that works out to roughly 4h 08m of airborne time. The great-circle track leaves Atlanta westbound and spends most of the flight in subtropical air.

Leaving Atlanta

Atlanta sits on the southern edge of the Appalachian foothills at just over 1,000 ft. In late spring and summer the field builds heat driven cumulus by early afternoon, so mid day departures climb through thermals that morning ones avoid. The great-circle track leaves ATL westbound, and the first waypoint band of the flight sits close to 33.7N 92.9W. On a sector of 4h 08m, the climb to cruise takes roughly the first twenty to twenty five minutes.

Mountain wave over the Rockies

The midpoint of the ATL to LAX track lies near 33.8N 101.4W, about 1,563 km from Atlanta, 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 Los Angeles

Arrivals into LAX descend across desert and mountain terrain before reaching the coastal basin. The step from dry inland air into the marine layer is the usual explanation for the movement near the end of the descent. Descent normally begins around 33.9N 109.9W, roughly 782 km before LAX, 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.
