When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 20 days in advance, which can save you up to 48% on flights from London to Idaho compared to booking the week you need them. Waiting 20 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 $765. For sooner than that we have options available in the next 3 days from $1,038.
Due to multiple factors, expect to potentially pay more when booking in July. For low rates, November can be a great choice for travel to Idaho. Flights to Idaho from London in November are about $889 on average during November, but can be found for as low as $647.
When flying from London to Idaho, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.

When I was going to board, one of the staff members told me that I could not board with my passport bag because it was tree items and I would need to check a bag. This was so stupid ! The bag was small. So I had to put my things in my pockets, put the funny bag inside the other bag. Then go throw it. Then in the plane put everything back again in my funny bag.
