When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 16 days in advance, which can save you up to 37% on flights from Green Bay to Montana compared to booking the week you need them. Waiting 16 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 $139. For sooner than that we have options available in the next 3 days from $216.
Due to multiple factors, expect to potentially pay more when booking in February. For low rates, July can be a great choice for travel to Montana. Flights to Montana from Green Bay in July are about $199 on average during July, but can be found for as low as $87.
