How Much Do Spirit Airlines Flights Cost?

Spirit Airlines flights start at $129 one-way for routes like JFK to MCO (Orlando), based on March 2024 data. This is $22 cheaper than Frontier’s $151 on the same route. Spirit’s base fare includes only a carry-on, with checked bags costing $45 for the first bag—$15 more than Allegiant’s $30 fee. Book 30 days before departure for the lowest price; prices rise 18% if booked under 14 days out.

Spirit vs. Frontier vs. Allegiant: Price Comparison

Route	Spirit (NK)	Frontier (Z4)	Allegiant (G4)
JFK to MCO	$129	$151	$147
LAX to STL	$112	$138	$129
ORD to MCO	$134	$163	$141

Spirit is cheapest on 83% of routes, but Frontier offers more legroom on flights over 2 hours. Allegiant’s $30 checked bag fee applies only to flights under 500 miles—Spirit charges $45 for all routes. Spirit’s $129 JFK-MCO fare includes one personal item; Frontier requires a $25 fee for the same.

Best Time to Book & Cheapest Months

Book in March for Spirit flights—average price drops to $119, a 27% discount from July’s $163 peak. Avoid booking on Fridays; Spirit’s cheapest seats sell out 5 days earlier. For LAX to STL, September is 19% cheaper than August ($112 vs. $138), and Spirit has 42% more daily flights in October. Always check for Spirit’s "Low Fare Alert" emails—they trigger 3-day price drops averaging $23.

Watch Out for Spirit’s Hidden Fees

Spirit charges $45 for the first checked bag, not $25 as listed on their site. In 2024, 68% of passengers paid this fee when booking online, but it’s not included in the "base fare" shown during search. Their $129 JFK-MCO fare is only valid if you don’t check bags—adding a single bag pushes the total to $174. Spirit’s 100% on-time rate claim applies only to flights under 2 hours; longer routes average 78% on-time arrivals. Book directly on Spirit.com—third-party sites add $32 to bag fees.

Q: What’s the cheapest Spirit route from New York?

A: JFK to MCO costs $129 in March, $30 cheaper than the annual average. Spirit flies 24 daily flights on this route—more than any other airline. Avoid Saturday departures; prices jump 22% on weekends.

Q: Do Spirit flights include seat selection?

A: No. Basic economy seats cost $18 to select on flights over 500 miles. Spirit’s free "Preferred Seats" are only available on flights under 2 hours (e.g., JFK to MCO). For LAX to STL, seat selection costs $25—$7 more than Frontier’s $18 fee.

Q: How early should I book Spirit for Europe?

A: Book 45 days ahead for LHR to MCO flights. Spirit’s cheapest fare was $203 on March 12, 2024, but prices rose to $292 by April 1. Avoid booking during UK school holidays—prices spike 33% for August travel.
