FAQs for booking flights from San Jose to London

  • Are there any visa requirements to be allowed into London?

    At the moment, US citizens can travel visa-free in and out of the United Kingdom as long as their stay doesn’t exceed six months. You will, however, still need your passport to be valid and have at least six months of validity left with one blank page for the immigration stamps.

  • What are the layover options from San Jose to London?

    Your layover options are limited to the airline you will be traveling with since most airlines prefer to schedule their layovers in one of the hub cities. For instance, if you are on a United Airlines flight, you are almost guaranteed to have your layover either in Houston or Denver. On the other hand, when traveling with Virgin Atlantic, the most probable layover destination is Los Angeles.

  • Which London airport is the best to land in?

    Travelers landing in London have the option of London Gatwick Airport (LGW) or London Heathrow Airport (LHR). London Heathrow is bigger than Gatwick and a major international hub, therefore, a good option if you’re connecting to a different country. It is also closer to Central London compared to Gatwick Airport. However, due to its status as a major hub, it is often very busy and experiences long queues compared to London Gatwick.

  • Can I get a train from London Heathrow Airport to Central London?

    Yes, there are three train options from Heathrow Airport to Central London. The fastest is Heathrow Express which runs up to 4 times an hour and takes only 15 minutes to reach London Paddington station. This train can be boarded from Heathrow Central Station. The other train options involve the London Underground via the Piccadilly Line to Piccadilly Station and the Elizabeth Line to Paddington Station. Both can be accessed from one of the three Heathrow underground stations. Alternatively, you can always take a taxi to your preferred destination as sometimes the underground is usually overcrowded, especially during rush hours.

  • What is the cheapest flight from San Jose to London?

    In the last 3 days, the lowest price for a flight from San Jose to London was £260 for a one-way ticket and £442 for a return.

  • Which aircraft models fly most regularly from San Jose to London?

    We unfortunately don’t have that data for this specific route.

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

    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 San Jose to London.

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

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

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

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

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

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.

Food was excellent. Service was very good. Staff was very helpful to all passengers.
