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.

Top tips for finding a cheap flight from London to California

  • Morning departure is around 5% more expensive than an evening flight, on average*.
  • 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.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

Very comfortable flights. Not so many new releases in terms of films.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

Uncomfortable seat/ bed. Opted for a front window seat without TV not working ). A bit smelly blanket and environment inside.

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

Pros: "The crew was amazing and took measures to make the flight Covid safe"
Cons: "The food was not the best and Twistees weren't available. Also the seats felt narrow"

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

3 hours delayed Don’t understand why when you have paid for ‘speedy boarding’ they call you forward to then make you stand fir another 20 minutes in a confined space before boarding the plane.

The pilot did everything possible to make up the 35 minute delay. His communications were honest, prompt and positive throughout.

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

The boarding process was fast and easy , but the airport sign was not up on the board, so it was hard to know the correct gate , on the airplane there was NO Snacks and NO water …. Everything needs to be purchase …. It’s not worthy for the price we paid !

Booked through you used Kiwi who did not complete checking in until 24 hrs before departure when the check in was available 48 hrs before hence we sat separately. I will not be using you again.

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Seating space was crowded and I am a very small woman.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.
