Travelers have found it’s best to book a flight 30 days in advance to save up to 17% 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 30 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 San Francisco to Tennessee 1-2 weeks in advance for as low as $179, or $197 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in April. For low rates, December can be a great choice for travel to Tennessee. Flights to Tennessee from San Francisco in December are about $202 on average during December, but can be found for as low as $95.
