Best Time to Book & Cheapest Months

March and April offer the lowest prices at 27% below summer rates, based on 2023-2025 data. I paid $320 for a March 2025 Spirit flight, while August prices average $520. Book 45 days before departure for the best fares—prices rise 18% if booked under 30 days. According to Eurostat 2025, 58% of Caribbean travelers book flights 45-60 days out for optimal pricing.

Hidden Fees & What to Avoid

Spirit Airlines charges $12.99 for a 10kg carry-on bag on the $295 base fare—most competitors include this. Booking through third-party sites like Booking.com adds a 14.5% "taxes and fees" charge not shown in the headline price, making a $320 flight cost $367.20. I learned this the hard way when I paid $367 for my March 2025 ticket through their platform, while the direct Spirit site showed $320. Always check the final price before confirming.
