Frequently asked questions

Is it cheaper to buy a plane ticket from San Diego Intl. Airport (SAN) to FLD last minute?
When it's time to book your flights, being prepared pays dividends. While it's possible to score a last-minute deal on a SAN to FLD flight, fares usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to lock in a domestic flight is between 28 – 35 days ahead. For international journeys it's three to four months.
