When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 53 days in advance, which can save you up to 341% on flights from Montana to Ontario compared to booking the week you need them. Waiting 53 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 $319. For sooner than that we have options available in the next 3 days from $556.
Due to multiple factors, expect to potentially pay more when booking in October. For low rates, January can be a great choice for travel to Ontario. Flights to Ontario from Montana in January are about $292 on average during January, but can be found for as low as $79.
When flying from Montana to Ontario, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.
