When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 31 days in advance, which can save you up to 21% on flights from USA to London compared to booking the week you need them. Waiting 31 days out may not be for everyone, so we have options available for flights within the next two weeks, with the lowest price starting at $653. For sooner than that we have options available in the next 3 days from $744.
Due to multiple factors, expect to potentially pay more when booking in June. For low rates, February can be a great choice for travel to London. Flights to London from USA in February are about $629 on average during February, but can be found for as low as $352.
When flying from USA to London, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.
