When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 22 days in advance, which can save you up to 244% on flights from Idaho to Illinois compared to booking the week you need them. Waiting 22 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 $325. For sooner than that we have options available in the next 3 days from $475.
Due to multiple factors, expect to potentially pay more when booking in May. For low rates, September can be a great choice for travel to Illinois. Flights to Illinois from Idaho in September are about $361 on average during September, but can be found for as low as $129.
Regardless of the time of day you decide to fly, the ticket price will remain around the same. Book flights from Idaho to Illinois as you normally would.
