When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 11 days in advance, which can save you up to 115% on flights from Illinois to Portland compared to booking the week you need them.

For sooner than that we have options available in the next 3 days from $558.
Due to multiple factors, expect to potentially pay more when booking in July. For low rates, January can be a great choice for travel to Portland. Flights to Portland from Illinois in January are about $352 on average during January, but can be found for as low as $158.
