Las Vegas to San Francisco: Route overview

This short-haul route from Las Vegas (LAS) to San Francisco (SFO) covers 665 km in approximately 1h 23m to 1h 51m. Since Las Vegas and San Francisco share effectively the same UTC offset, jet lag is not a factor, though the travel time itself can cause fatigue. Both cities sit at similar temperate latitudes, meaning daylight patterns will feel familiar upon arrival — a helpful factor for circadian adjustment.

What makes the Las Vegas–San Francisco route different

This route is unusual in that it covers a substantial distance (665 km) without crossing time zones. The main challenge is travel fatigue from the short-haul flight rather than circadian disruption, making recovery straightforward — usually within 24 hours.

Seasonal and climate factors

Short-haul flight times on this short-haul route are less affected by seasonal wind patterns, though winter weather can cause delays at both Las Vegas and San Francisco airports. San Francisco at 38°N experiences moderate seasonal daylight variation. Summer offers longer evenings useful for westward adjustment, while winter's earlier sunsets support eastward adjustment schedules.

How the Las Vegas–San Francisco flight time is estimated

The 1h 23m to 1h 51m estimate for Las Vegas to San Francisco is derived from the 665-km great-circle distance. As a short-haul route, a larger proportion of flight time is spent climbing and descending rather than at optimal cruise altitude, resulting in a lower effective speed of 650–750 km/h. An additional 30–50 minutes accounts for taxi, takeoff, climb, descent, approach, and taxi at both LAS and SFO. Actual routing through controlled airspace may add 3–8% distance beyond the great-circle path due to air traffic corridors and restricted zones along the way.

Wind patterns and flight duration

On this short 665-km route, wind effects are relatively minor compared to the fixed overhead of taxi, takeoff, and landing. The main variable in flight time is airport congestion and weather at LAS and SFO.
