Travelers have found it’s best to book a flight 17 days in advance to save up to 27% 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 17 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 Santa Maria to San Diego 1-2 weeks in advance for as low as $73, or $98 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, July can be a great choice for travel to San Diego. Flights to San Diego from Santa Maria in July are about $80 on average during July, but can be found for as low as $44.
