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

FAQs - booking California flights

  • I’m booking a flight to California to visit San Francisco. Which airport do I choose?

    San Francisco International is the closest to the city centre (15min) and has the most options when it comes to airlines and routes. United, British Airways, and Virgin Atlantic operate direct flights from London Heathrow, Norwegian flies from London Gatwick, and Thomas Cook Airlines operates seasonal flights to SFO from Manchester. However, this is one of the busiest airports in California; if you’d prefer a less busy airport, you can fly to San Jose International, which is 47min from downtown San Francisco. However, do keep in mind that British Airways is the only airline to operate regular flights to this airport from London Heathrow.

  • I’m planning a trip to Yosemite National Park. What’s the best airport to fly into?

    The closest airport to Yosemite is Fresno Yosemite International Airport (FAT), about 96 mi away from the park and accessible by road. If you want to fly from the United Kingdom all the way to Yosemite, you'll have to have a stopover either in San Francisco or Los Angeles. United flies from Heathrow and Gatwick to San Francisco and Los Angeles, while American Airlines flies to Los Angeles from Heathrow. Alternatively, or if you’d prefer to fly as little as possible, you can fly into San Francisco and then drive to Yosemite (approx. 3h 50min).

  • Which international airport in California is closest to Disneyland?

    Los Angeles International Airport is the closest to Disneyland California, which is about 35min away by car. This airport is served by the Disneyland Resort Express bus, which takes passengers straight to the park.

  • I’m searching for flights to California from Northern Ireland. Which are the best airports?

    If your final destination is Los Angeles or San Francisco, you can choose to catch a flight to California from London Heathrow with British Airways, Virgin Atlantic, and United, or from London Gatwick with Norwegian. easyJet operates direct flights to Gatwick from Belfast International Airport (BFS), while Aer Lingus and British Airways operate regular flights to Heathrow from George Best Belfast City Airport (BHD). If you’re flying to San Jose or San Diego, you’ll have to fly out of London Heathrow on British Airways. The simplest option is to book your flight to California with this airline from Belfast International.

  • How does KAYAK find such low prices on flights from the United Kingdom 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 the United Kingdom to California.

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

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United Kingdom 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 the United Kingdom 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 the United Kingdom 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 the United Kingdom 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 the United Kingdom 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 day to fly to California?

On the other hand, Gatwick has more options for low-cost flights with easyJet operating regular connections with Belfast, Glasgow, and Inverness.
  • When looking for flights to California, you can choose from four international airports with regular direct flights to the UK.

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Empty seats next to me - wish it had been for a longer flight!!

Terrible last row seats many seats available but no offer to move to better seat

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

My seat 3G did not go down fully and the buttons were not working properly

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

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

Flight attendants had a little attitude. Food tastes no good.

Overall we had a good experience during our flight from San Francisco to Houston.

it was a very short flight so my expectations were low.

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

It was good. The seats in economy weren’t bad

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Excellent service; they helped me reschedule so I can fly in an earlier flight

Wonderful staff. The boarding process can be improved a little better by adequate prior communication but all in all they did fine. However the boarding gate was quite unfreindly to elderly and who needs help with sevral stairs.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

Very good. Comfortable and I felt well taken care of from start to finish

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

Not great - seats were very narrow and food was terrible.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

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.
