Flying out of Los Angeles LAX
Los Angeles is the West Coast's long-haul anchor and the natural departure point for anything crossing the Pacific. LAX's advantage on India and Southeast Asia routes is directional: westbound itineraries via Tokyo, Seoul, Taipei or Singapore are frequently faster and cheaper from LAX than the eastbound routings a booking site will show you first, because the site is optimising for the shortest map line rather than the actual schedule. Artesia's Little India and the wider Southern California diaspora make this a high-volume corridor where unpublished fares turn over quickly.
What to know before you fly to London
Entry requirements for US travellers
US citizens can visit the UK without a visa for short stays but now need an Electronic Travel Authorisation (ETA) before flying. It is applied for online and approval is usually quick, but it is a genuine requirement and airlines do check — apply through the UK government's official service, not a third-party site that charges a fee.
Best time to go
May, June and September give the best combination of weather and price. July and August are peak in both directions. January and February are the cheapest months of the year on the transatlantic corridor by a wide margin, and London is a perfectly good winter city.
Airports and arrival
Heathrow (LHR) has the widest schedule and the best onward connections. Gatwick (LGW) frequently carries lower fares on the same dates, and Stansted and Luton serve the budget European network — worth knowing if London is a stepping stone rather than the destination.
Baggage
Transatlantic economy now spans basic fares with carry-on only through to fares including two checked bags, at prices that are much closer together than they look. Matching the fare to how you actually pack is the whole game on this route.

Los Angeles to London — frequently asked questions
Fares on the Los Angeles–London route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include British Airways, Virgin Atlantic, American, Delta, United and Norse Atlantic. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer nonstop, with heavy daily competition, and total journey time runs about 10–11 hours. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.

Yes — this route has nonstop service, with nonstop, with heavy daily competition. Nonstop is not always the cheapest option: a one-stop itinerary on the same dates is frequently a few hundred dollars less, and on a journey of 10–11 hours that trade is worth pricing rather than assuming. Frequencies change by season, so call us for what is actually flying on your dates.
LAX carries all of the region's long-haul flying, but Southern California has four other airports — Burbank, Long Beach, John Wayne and Ontario — that can be far more convenient for the first leg of a connecting itinerary and are often cheaper. If your trip connects anyway, starting it from the airport nearest you rather than fighting across the basin to LAX is worth pricing.
Less than on the long-haul Asian routes, honestly — transatlantic economy is the most competitive market in aviation and the public fares are genuinely keen. Where we do earn our place is on the fare rules: basic economy on this corridor is restrictive in ways that are easy to miss, and the fare that includes a bag and a free change is frequently only a little more. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
