Flight time: Toronto to Los Angeles

Route details

Distance breakdown: Toronto to Los Angeles

The 3,494-km great-circle distance between Toronto (43.68°N, 79.62°W) and Los Angeles (33.94°N, 118.41°W) spans 9.7° of latitude and 38.8° of longitude, trending primarily west. In miles, this is 2,171 mi or 1887 nautical miles. The great-circle path — the shortest distance over Earth's curved surface — is calculated using the Haversine formula from the two airports' precise coordinates.

Cruise speed and flight phases

At 3,494 km, this medium-haul route falls in the operational sweet spot where aircraft reach cruise altitude for a meaningful portion of the flight. Effective cruise speeds of 780–850 km/h are typical, with narrow-body aircraft (A320neo, 737 MAX) handling the lower end and wide-body aircraft achieving speeds at the upper end. The 4h 37m to 5h 19m estimate accounts for approximately 20 minutes of combined climb and descent, with the remainder at efficient cruise altitude.

Ground time and routing overhead

Our 30–50 minutes overhead allowance covers: taxi-out at YYZ, takeoff and initial climb, descent and approach at LAX, and taxi-in to the gate. YYZ is a major international hub where taxi times of 15–25 minutes are common during peak periods. At LAX, arrival taxi and gate assignment can add 10–20 minutes, especially during busy arrival banks. Continental air traffic corridors between Toronto and Los Angeles may add 3–8% beyond the great-circle distance. Standard instrument departures and arrivals at both airports use predefined routing that adds distance but ensures safe separation.

Return flight: Los Angeles → Toronto

The return flight from Los Angeles to Toronto is generally similar in duration to the outbound — typically within 10–20 minutes. Continental routes like this one are less affected by the jet stream asymmetry that makes oceanic east-west routes so uneven. The main variables affecting any difference are: prevailing winds at these latitudes (modest effect), different standard instrument departures/arrivals at each airport (minor effect), and air traffic congestion patterns that vary by time of day and direction.

Seasonal variation in flight times

Flight times between Toronto and Los Angeles vary modestly by season — typically 10–20 minutes. Upper-level wind patterns shift with the seasons: winter generally brings stronger westerly winds at these latitudes, while summer patterns are more variable. Thunderstorm activity along the route corridor peaks in summer months, occasionally causing routing diversions that add distance. Winter operations may include de-icing delays at YYZ, which extend the overall gate-to-gate time.

Airport information

Toronto Pearson International Airport (YYZ) is a major international hub in Toronto, Canada. As a tier-1 airport, it handles high traffic volumes, which means longer average taxi times but also higher flight frequency and competition that can benefit travelers on pricing. Los Angeles International Airport (LAX) is a major international hub in Los Angeles, United States. As a tier-1 airport, it handles high traffic volumes, which means longer average taxi times but also higher flight frequency and competition that can benefit travelers on pricing.
