When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 17 days in advance, which can save you up to 5% on flights from New Hampshire to Costa Rica compared to booking the week you need them. Waiting 17 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 $393. For sooner than that we have options available in the next 3 days from $422.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, October can be a great choice for travel to Costa Rica. Flights to Costa Rica from New Hampshire in October are about $404 on average during October, but can be found for as low as $205.
