We recommend booking at least 53 days in advance, which can save you up to 115% on flights from Illinois to Portland compared to booking the week you need them.

Due to multiple factors, expect to potentially pay more when booking in June. For low rates, January can be a great choice for travel to Portland. Flights to Portland from Illinois in January are about $358 on average during January, but can be found for as low as $158.
