Cheap Flights to London

As one of the world's most popular cities, London has thrilled, entertained and captivated visitors for many years. Its history is everywhere to be seen, but the buzz of contemporary culture is never too far away. It’s just a short hike from the antiquity of the Tower of London and Big Ben to the nightlife of SoHo and the iconic Tate Modern art gallery.

How to find cheap flight deals to London

When searching for cheap flights to London on Expedia you can use the ‘Nearby Airports’ option under your chosen departure location to explore deals available from other airports. You can also select to search for flights that arrive at any London airport to ensure you don’t miss out on a cheaper fare.

If you are flexible on the dates of your flight, another great tip for finding the cheapest flight is to select ‘Show Flexible Dates’ – which appears just above where your flight options are returned – to find the best price for tickets to London.

    Two major airports in London are Heathrow Airport and Gatwick Airport.

    When to book a cheap flight to London

    If it’s festivals that you are after – and the chance to enjoy London’s many open spaces such as Hyde Park or Richmond Park – then, undoubtedly, the summer months are your best bet. But, London does get busy at this time of year, so cheaper flights may be thinner on the ground, and it’s advisable to book attractions in advance so you can skip the inevitable queues.

    Autumn is an attractive season for visiting London, as the weather remains mild and the events, such as the Totally Thames festival and celebrations for Halloween, are plentiful.

    From mid-November the Christmas lights illuminate London’s streets each night, and there are a number of Christmas markets that spring up alongside more traditional shopping destinations. And, of course, there’s the fireworks over the Thames and the January sales to consider as an option too.

    If you are planning on flying during spring you should take note of when Easter falls: there are often public transport closures during this time.

    When there are free seats in business they should be given to select passengers to make them more loyal customers
