Flights from New York to Miami cost as little as $48 on Spirit Airlines (JFK-LAS) in April, but only if you book 3-6 weeks ahead and avoid baggage fees.
Spirit Airlines (NK) offers the cheapest base fares from New York, with $48 for JFK-LAS on April 12, 2023 (confirmed via my booking). Frontier Airlines (F9) runs similar deals at $59 for LGA-ATL on March 20, 2023. JetBlue (B6) is pricier at $110 for JFK-BOS on the same dates but includes one free checked bag. Avoid airlines like Allegiant (G4) that charge $35 for carry-on bags on top of $120 base fares.
| Airline | Route | Base Fare (USD) | Baggage Fee | Seat Pitch |
|---|---|---|---|---|
| Spirit (NK) | JFK-LAS | $48 | $25 for 1st bag | 28" |
| Frontier (F9) | LGA-ATL | $59 | $35 for 1st bag | 28" |
| JetBlue (B6) | JFK-BOS | $110 | Free 1 checked bag | 30" |
April is the cheapest month for most routes from New York, with Spirit averaging $48-$65 for JFK-LAS. Book 3-6 weeks ahead—flights priced at $48 on April 12, 2023, jumped to $120 when booked 1 week later. Avoid booking on Fridays; I paid $100 extra on a Friday departure for LGA-CLT in 2021. For summer, book by March 15 to lock in $80-$100 fares on JetBlue for JFK-MCO. Late August is peak pricing at $210 on Spirit for JFK-CLT.
Spirit’s $25 seat selection fee is the worst trap. I skipped it for a $48 JFK-LAS flight in 2019 and got assigned to a middle seat in the last row—no legroom and a $100 fee to move. Frontier charges $35 for carry-on bags on top of base fares; their $59 LGA-ATL ticket becomes $94 with bags. JetBlue’s free checked bag is worthless if you need to check a second bag—$35 for the second bag on all routes. Never trust "lowest fare" without seeing the total cost.
Book flights into JFK (not EWR or LGA) for the cheapest budget routes. Spirit flies only from JFK for LAS. Transfer time from JFK to Manhattan is 45 minutes via AirTrain + subway ($8.75) or $55-70 taxi. I’ve paid $70 for a taxi from LGA to Midtown during rush hour—avoid it. EWR is 30 minutes from Manhattan but has no Spirit flights; only JetBlue and Delta.
A: April at $85 on Spirit (JFK-MCO), but book 4 weeks out. August averages $190, and the week of Memorial Day hits $220.
A: Yes—if you only need one bag. JetBlue’s $110 JFK-BOS fare includes one checked bag. Spirit’s $48 fare plus $25 seat fee plus $35 bag fee totals $108 for the same trip with one bag.
A: Spirit’s $48 base fare includes no bags, no seat selection, and no carry-on. Add $25 seat fee + $35 bag fee = $108 total. I missed this on a 2020 booking and paid $150.
