Travelers have found it’s best to book a flight 37 days in advance to save up to 26% compared to booking the same week of travel. As your travel date approaches, the cost of this flight route may potentially increase. While opting to book 37 days out may not be an option for all, there are still additional ways to secure a deal in the near future. You might find a flight from Illinois to Fresno 1-2 weeks in advance for as low as $105, or $135 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in July. For low rates, October can be a great choice for travel to Fresno. Flights to Fresno from Illinois in October are about $120 on average during October, but can be found for as low as $80.
