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 £203 for a one-way ticket and £523 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.

  • Which airline alliances offer flights from San Jose to London?

    Star Alliance, SkyTeam, and oneworld are the airline alliances operating flights between San Jose and London, with oneworld being the most commonly used for this 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?

  • 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?

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We had an unfortunate experience where we had to leave the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason given was that a passenger felt ill and had to cancel their plans and therefor their luggage had to be found and removed.

We’ve used VA before many times the experience is always been good they have lovely staff and the food is always delicious.

Everything about the flight was amazing from check in to boarding entertainment was okay food we didn’t try.
