Flight Time from LAX to London Heathrow: Everything You Need to Know

Several variables determine how long your flight actually lasts:

1. Wind and Jet Streams

Flights heading east (like LAX to London) benefit from strong tailwinds, often reducing the flight time. The return flight, however, is usually longer due to headwinds.

2. Flight Path

Not every plane follows the exact same route. Some take a more northern path over Greenland while others fly over the Atlantic directly, depending on weather and air traffic.

3. Airport Delays

Heathrow and LAX consistently rank as two of the most active airports worldwide. Delays on the runway or during approach can add 30 minutes or more to your total journey.

4. Aircraft Type

Modern aircraft such as the Boeing 787 Dreamliner and Airbus A350 tend to have slightly faster and more fuel-efficient flight times compared to older planes.
