When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 52 days in advance, which can save you up to 32% on flights from Seattle to Mexico compared to booking the week you need them. Waiting 52 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 $302. For sooner than that we have options available in the next 3 days from $320.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, May can be a great choice for travel to Mexico. Flights to Mexico from Seattle in May are about $262 on average during May, but can be found for as low as $189.
