When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 41 days in advance, which can save you up to 11% on flights from Flint to Puerto Rico compared to booking the week you need them. Waiting 41 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 $380. For sooner than that we have options available in the next 3 days from $415.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, September can be a great choice for travel to Puerto Rico. Flights to Puerto Rico from Flint in September are about $380 on average during September, but can be found for as low as $194.
