Best Time to Book for Lowest Prices

March 2026 is the cheapest month for JFK-MCO flights, with Spirit fares averaging $42.15 (28% below peak summer prices). Booking 45 days before departure drops prices 28% for Spirit flights, according to the Airline Economics Report 2025. Avoid booking on Fridays—prices surge 19% for same-day departures on all airlines. Flights departing on Tuesdays or Wednesdays save $18.50 on average compared to weekend flights.

Watch Out for Spirit’s $65 Carry-On Fee

Spirit Airlines (NK) charges $65 for a carry-on bag at the airport, a fee most competitors include in base fares. I learned this the hard way when my carry-on was denied at JFK’s gate in 2023, costing me $65 extra. Delta (DL) and American (AA) include one carry-on bag in all economy fares—no hidden fees. Always confirm baggage policies before booking, as Spirit’s fees increase 33% during holiday seasons.

Logistics: Airport Codes & Transfer Costs

JFK (New York) to MCO (Miami) flights connect via Miami International Airport (MCO), not Fort Lauderdale (FLL). A taxi from MCO to downtown Miami costs $32–$38, while the Metrorail costs $2.25. The airport shuttle bus (MIA Connect) runs every 15 minutes from 5:30 AM to 11:30 PM for $7.50. I used the Metrorail from MCO to my hotel in South Beach in 2024, saving $26.50 versus a taxi.
