If flying business class I’d research which cabin your aircraft operates. BA have some old business class on the 380 and new business class on the 777. (And 350). The new cabin is so much better. But the food just isn’t as good as it used to be

Heathrow is vast, allow plenty of time to drop bags and go through security. At San Francisco the immigration takes a bit of time and we had to wait around 1.5hrs, bare this in mind when booking car rental. The is a shuttle train from the airport to the car rental area which is very slick and efficient.

In London triple check your flight they have multiple leaving for the same destination once - it is easy to get them confused

FAQs - booking California flights

  • What’s the cheapest way to get from San Francisco Airport (SFO) to the city centre?

    The most reasonably priced method of transport when it comes to getting to downtown San Francisco is the service provided by the BART, which is a metro/train service that only takes 30 minutes and costs around $10 (£8.20). You can get to the airport train station using the AirTrain, departing from all terminals at the airport. You can get tickets and continue your journey to the Antioch-SFO/Millbrae Line, which is a subway line and you can reach all popular central metro subway stations from here.

  • Where can I find car hire at Los Angeles Airport (LAX)?

    You may hire a car from Alamo, Avis, Budget, Dollar, Enterprise, Fox, Hertz, National, Thrifty, Zipcar, and SIXT at the airport. The offices and rental car facilities are located to the east of the airport. The automobile rental firms are accessible via the free shuttle bus service; simply follow the purple Rental Car Shuttles signs to the bus stops.

  • How do I reduce my carbon footprint when flying from London to California?

    To reduce your carbon footprint when flying to California from London, it’s best to consider flying from London Heathrow Airport (LHR) with British Airways to Los Angeles Airport (LAX) with one stopover in Philadelphia Airport. You can also fly the same route with American Airlines, and both flights would reduce your carbon emissions by 37-38%.

  • What are the best options for parking at Heathrow Airport (LHR)?

    It may depend on how long you need parking, but at Heathrow Airport, you can choose from various car parks. The long-stay parking lot usually offers the greatest prices, so park here. Depending on the length of time you require, you will typically be charged between £18 and £20 each day. This package also includes a free shuttle bus journey to the terminal, which takes approximately 10 minutes.

  • How does KAYAK find such low prices on flights from London to California?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from London to California.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from London to California?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from London to California is likely to change within 7 days, so travellers know whether to wait or book now.

  • What is the Hacker Fare option on flights from London to California?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly from London to California with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from London to California?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from London to California up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • What is the cheapest time of day to fly to California?

    The cheapest time of day to fly to California is generally in the morning, when retur flights cost £492 on average. Morning departures are around 10% cheaper than evening flights, on average.

Top tips for finding a cheap flight from London to California

  • When it comes to flying from London airports, you can take advantage of the Click & Collect online duty-free service and pay for your goods ahead of your arrival at the airport. Once you arrive at the airport you can pick-up your order before you head to the departure gate.
  • Make an online reservation for the Heathrow Express Train from Paddington Station to get from central London to London Heathrow Airport (LHR). Three months in advance, you may save around £20 since tickets are around £5.50, the ticket gets gradually more expensive the closer you get to the travel date and costs £25 on the day of travel, so it's worth it to reserve ahead of time if possible.
  • If you want to relax and unwind prior to taking your flight, airports such as London Heathrow Airport and London Gatwick Airport (LGW) have excellent lounge services, which you can reserve online prior to getting to the airport. Typically, prices range from £25-42 at Heathrow, and £32-38 at Gatwick.
  • To save money on flights from London to California, the best option is to fly out of London Gatwick Airport on flights that have at least one stopover. You can fly with Norse Atlantic Airways to Los Angeles Airport (LAX) via New York John F. Kennedy Airport (JFK) and self-transferring to Newark International Airport (EWR) and connecting with Alaska Airlines to Los Angeles.
  • If you simply want to fly from London to California, you can only do it through London Heathrow Airport. These flights are often more expensive than others that involve a stopover; for the cheapest and most frequent flights, we recommend checking fares with Austrian Airlines, who fly directly to Los Angeles Airport.

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Both flights delayed. 2nd flight over 3 hours late mechanical issues

Flight was delayed 45 minutes because originating flight was coming from Newark. No complimentary snacks were offered on this 5+ hour flight. No screens for the flight, but movies offered if you had already downloaded the United app (which I hadn't on my ipad). No USB ports, only a flimsy plug-in port near the bottom of the seat that was hard to see and kept coming unplugged.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

On the way my flight entertainment wouldn’t work the screen went black and no matter how many times I tried to turn it on it wouldn’t. Food was surprisingly good but the tray tables were tiny so you couldn’t get anything else on the table. The seats hardly go back and are not overly comfortable. Wouldn’t fly United again.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

The friendly staff. They kept time. Was suprised to get some drinks.

We did not even get on this flight as the plane never left London. I missed the email that was sent mid morning USA time, so we were not aware the flight was cancelled. There was absolutely no help from the staff at the Norse check in gates, we were told to take a picture of the board they were holding up, to try and claim our money back. We were told to book our own flights to London which ended up costing $10000 due to the last minute. And now we have to return to Miami in 2 weeks. I am not holding my breath about getting on board for that flight either.

Great experience. The flight was smooth with very little turbulence. We were in premium classic, so lots of leg room.

Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that

Unexpectedly was surprised with the space on flight in economy and the price.

I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.

Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.

The movies were super old. The crew did not offer WATER???? 5 hours os flight and did not get WATER? Norse is the worst company I ever used and never will use again.

Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!

We flew one way from Gatwick, London to JFK NY For 2 people $1200 and no food offered not even water. You had to buy food. Norse advertises as a low fare transatlantic airline, they may want rethink that. Crew, flight was fine. Ironically we flew American from JFK to Heathrow for $1000 (2people) and included food and drinks.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Never happened. Flight was delayed. Had to be re rojyed

Lufthansa is my favorite airline and have flown oversea with them for the past 25 years: i always found them so professional and incredibly efficient from checking in to arrival. I also love their Munich or Frankfurt airports.

We paid for business class, and my seat did not work at all. Each time I wanted to adjust the position, an attendant had to come to physically force the seat into its new position. They tried to fix it by fiddling with the electronics (military reset, for example), to no avail. Also, the food was just mediocre. We were at the end of a serving section, so they ran out of several choices. (This was on the flight from Los Angeles to Munich.)

The flight was delayed by an hour. Made the connection uncomfortably tight.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.
