Travelers have found it’s best to book a flight 20 days in advance to save up to 28% 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 20 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 Billings to Columbus 1-2 weeks in advance for as low as $164, or $224 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, April can be a great choice for travel to Columbus. Flights to Columbus from Billings in April are about $175 on average during April, but can be found for as low as $42.
