The duration of a nonstop flight between San Diego International Airport (SAN) and London’s primary airports (typically Heathrow, LHR, or Gatwick, LGW) averages between 10 and 11 hours. This can vary based on factors such as aircraft type, wind conditions, and specific flight paths. Connecting flights, which involve a layover at an intermediate airport, can significantly extend the total travel time, sometimes to 14 hours or more. Precise flight durations are always available from specific airline schedules.
Understanding anticipated travel time is crucial for effective trip planning. Accurate estimations facilitate informed decisions regarding flight selection, connection times, and overall itinerary construction. This allows travelers to minimize potential disruptions, optimize time spent in transit, and ensure a smoother, less stressful travel experience. Historically, transatlantic flights were considerably longer, making modern air travel remarkably efficient in connecting distant cities like San Diego and London.
