The return flight from London to Los Angeles is longer at 11–12 hours due to prevailing headwinds.

Why the Return Flight Is Longer
The jet stream — a band of fast-moving air at cruising altitude — flows from west to east across the North Atlantic at speeds of 100–200 mph. Eastbound flights from Los Angeles ride the jet stream as a tailwind, shaving roughly 30–60 minutes off the flight. Westbound flights from London must fly against it, adding time and fuel consumption.
Common Connection Cities

| New York (JFK) | JetBlue, British Airways, American | 3–5 hours |
| Chicago (ORD) | American, United | 3–5 hours |

| San Francisco (SFO) | United | 3–4 hours |
| Reykjavik (KEF) | Icelandair | 4–6 hours |

Connecting through East Coast hubs like JFK or ORD generally adds the least time. Connecting through Reykjavik or Dublin can offer lower fares but adds more total travel time.

Tips for the LAX to London Flight
- Book an evening departure — most nonstop flights leave LAX at 7–10 PM, arriving in London the next afternoon. This lets you sleep on the plane and arrive with some daylight
- Consider Premium Economy — on a 10+ hour flight, the extra legroom and seat recline are worth the upgrade, often 30–50% more than economy
- Adjust your watch immediately — start living on London time as soon as you board to reduce jet lag
- Stay hydrated — the cabin humidity on long-haul flights drops to 10–20%, far below the comfortable 30–65% range
- US customs preclearance does not apply on this route — you clear UK immigration upon arrival at Heathrow
