When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 45 days in advance, which can save you up to 10% on flights from Cardiff to Vientiane compared to booking the week you need them. Waiting 45 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 £539. For sooner than that we have options available in the next 3 days from £610.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, November can be a great choice for travel to Vientiane. Flights to Vientiane from Cardiff in November are about £576 on average during November, but can be found for as low as £451.
