How long is the flight from Los Angeles to London?
A nonstop flight from Los Angeles to London takes about 10 hours and 20 minutes, based on published schedules. The outbound LAX → LHR leg rides the jet stream eastbound and is usually a little shorter than the return against the headwinds. Scheduled block times run from roughly 10 h 15 on the fast end to 10 h 30 on longer rotations.
If you choose a one-stop itinerary — often the cheapest way to fly when nonstop seats are expensive — total travel time lands between 13 and 16 hours depending on the layover. Dublin is a popular connection because it clears US preclearance on the return; New York, Atlanta, and the big European hubs (Amsterdam, Frankfurt, Paris) all offer onward flights to London.
Which airlines fly the route (and which are cheapest)
- British Airways — the dominant carrier on LAX–LHR with multiple daily nonstops, the flagship transatlantic product, and usually a wide spread of fare buckets if you book early.
- Virgin Atlantic — BA’s main head-to-head rival, daily nonstops with a strong premium-economy and Upper Class product and competitive leisure fares.
- American Airlines — oneworld partner of BA, codeshare-heavy; its own nonstops and shared pricing often match BA.
- United Airlines — nonstop from LAX to Heathrow, a useful option if you credit miles to MileagePlus.
Golden rule: because four carriers fight over the same seats, the cheapest nonstop is rarely from the same airline every week. Before you book, compare every Los Angeles–London flight on TopTravelCentre to see instantly which airline is cheapest for your exact dates.
Airports: LAX and London Heathrow
Los Angeles International (LAX)
The West Coast’s main transatlantic gateway. British Airways, Virgin Atlantic, American, and United all use the Tom Bradley International Terminal and adjacent terminals — check your terminal before you leave, because traffic between them on the airside bus can eat 30–40 minutes. Arrive three hours before an international departure; the Century Boulevard and 405 freeway approaches are notoriously slow at rush hour. The LAX FlyAway bus and the new people-mover links connect to Metro rail and regional transit.
London Heathrow (LHR)
Britain’s busiest airport and the natural arrival point for a Los Angeles nonstop. The Elizabeth Line reaches central London (Paddington, Bond Street, Liverpool Street) in under 30 minutes; the Heathrow Express is faster but pricier; the London Underground Piccadilly Line is the budget option. If you plan to keep traveling in Europe, see our guide to layovers and connections in Europe — a same-day train or short hop from Heathrow can reach Paris, Madrid, or Amsterdam.
Often-forgotten tip: if your real destination is elsewhere in Europe, a cheap LAX–London fare plus a low-cost onward flight can undercut a single LAX–Paris or LAX–Madrid ticket. Compare both — start with cheap flights London to Paris and cheap flights Madrid to London.
When is the cheapest time to fly to London?
Fare data points to the same low-demand windows year after year:
- February — the cheapest month on average, after the holiday rush and before the European spring.
- September, October, and November — the second-best window: London weather is still mild, the summer crowds leave, and fares fall hard from August peaks.
- Late January and early March — quiet shoulder weeks with reasonable prices.
When to avoid: late June through August (peak European summer and school holidays), the Christmas–New Year period, and Easter. Demand spikes and nonstop seats sell out. If summer is your only option, book two to three months ahead. Flying Tuesday, Wednesday, or Thursday is almost always cheaper than the weekend.

How much does a Los Angeles–London flight cost?
Prices change daily, so treat these as indicative ranges checked on the date shown, not a quote:
Checked on 09/08/2026. Prices verified across public flight search engines and official airline websites. In low-season windows (February, and September–November), booked two to three months ahead, a round-trip LAX–LHR in economy typically starts from about 550–700 USD. Normal low-season fares sit in the 700–950 USD range. In peak season (late June–August, Christmas, Easter) or booked last-minute, the same ticket can climb to 1,200–1,800 USD or more. These are ranges, not guaranteed prices — always check the live fare for your dates.

6 real tactics to get the cheapest flight
- Aim for February or September–November. The cheapest windows of the year on this transatlantic route.
- Book 2–3 months ahead. Not a year out, not last-minute — that is the sweet spot for LAX–London fares.
- Compare all four nonstop carriers. BA, Virgin, American, and United rarely price identically; the cheapest flips week to week.
- Weigh a one-stop itinerary. A connection via Dublin, New York, or a European hub can undercut the nonstop by hundreds.
- Fly mid-week and buy a round trip. Tuesday/Wednesday departures plus a return is usually the cheapest combination.
- Search all airlines at once. The fastest way to never miss a deal. For deeper tactics, read our complete guide to finding cheap flights.
Mistakes to avoid
- Booking only one airline’s site. You’ll miss the carrier that dropped its fare this week. Always compare across all airlines first.
- Ignoring the one-stop option. A two-hour layover can save several hundred dollars on a transatlantic ticket.
- Flying Friday or Sunday. Weekend departures are the most expensive days on this route.
- Forgetting total cost. A cheap fare with a long overnight layover or a far-out London airport costs more in time and ground transport.
Frequently asked questions
Is there a nonstop flight from Los Angeles to London?
Yes — four. British Airways, Virgin Atlantic, American Airlines, and United all fly LAX to Heathrow nonstop, with multiple daily departures. The flight takes about 10 hours and 20 minutes.
Do US citizens need a visa for the UK?
US passport holders do not need a visa for tourism visits to the UK of up to six months. You do need a valid passport and, since 2025/2026, an Electronic Travel Authorization (ETA) — apply online before you fly.
What is the cheapest month to fly Los Angeles to London?
February is typically the cheapest month, followed by the September–November shoulder window. Late June through August and the Christmas holidays are the most expensive.
Which London airport do I fly into from LAX?
All nonstop LAX–London flights arrive at London Heathrow (LHR). One-stop itineraries can also reach Gatwick (LGW), but the four nonstop carriers all land at Heathrow.
How early should I book?
About 2–3 months ahead for the best balance of price and schedule. Book earlier if you must travel in July, August, or around the holidays.

Often yes. A connection via Dublin, New York, or a European hub can be several hundred dollars cheaper than the nonstop and adds only a few hours.
Should I fly into Heathrow or Gatwick?
For Los Angeles nonstops, Heathrow is the default and the best connected to central London. Gatwick appears mainly on one-stop fares; it is farther out but has fast train links too.
