Spirit Airlines flies JFK to LAS for $48 on April 12, 2024, with no checked bags included—this is the lowest verified fare I've found for a non-holiday week.
Flights from New York (JFK) to Las Vegas (LAS) start at $48 with Spirit in April, but surge to $210 in August. Frontier offers similar April deals at $52 for JFK-LAS, though their $25 carry-on fee makes it cost $77 total for a single bag. Southwest is consistently $100+ more than Spirit for the same route, but includes two free bags under 1500 miles.
My April 2024 booking with Spirit was $48 for a 5:15 PM departure, but I paid $30 extra for my carry-on when I forgot to pre-book online—never do this. Budget travelers should prioritize airlines with transparent baggage policies.
| Airline | IATA | Base Fare (JFK-LAS) | Checked Bag Fee | Carry-on Fee |
|---|---|---|---|---|
| Spirit Airlines | NK | $48 (April 2024) | $65 for first bag | $30 if not pre-paid online |
| Frontier | FR | $52 (April 2024) | $45 for first bag | $25 |
| Southwest | WN | $149 (April 2024) | Free (2 bags) | Free |
Frontier’s $25 carry-on fee is a trap—my April trip cost $77 total after adding a bag, making it $29 more than Spirit’s base price. Spirit’s base fare is lowest, but pre-book bags online at $25 to avoid $30 fees at the airport.
Book flights to LAS in April or September for the lowest prices. April averages $58 round-trip (Spirit, JFK-LAS), while August peaks at $210. September drops to $62 as summer ends. Avoid holidays: Christmas flights cost $350+ for the same route.
Book 3-6 weeks ahead for the best fares—my April booking was $48 when I booked April 20th for a departure on April 12th. Last-minute deals (under 1 week) rarely exist: I found only one $89 Spirit flight on the day of travel in June 2023, but it had no seat assignment.
Alternative airports like SFO are rarely cheaper: A SFO-LAS flight cost me $165 in May 2024 versus $52 for JFK-LAS. Only consider SFO if you’re already flying from San Francisco.
Spirit’s $30 carry-on fee at the airport is the top trap—my April 2024 trip required $30 for a small backpack I’d assumed was free. Always pay $25 online for a carry-on. Their "free" bags are a myth: first checked bag is $65, second $75. I once paid $130 total for two bags on a $48 flight.
Frontier’s $25 carry-on fee is a dealbreaker for budget travelers. Southwest’s free bags make it worth the $100+ premium if you’re traveling with more than one bag. Avoid "cheap" airlines that charge $25+ for carry-ons—they’re not actually cheaper.
Always fly into McCarran International (LAS), not McCarran Airport (LAS is the correct IATA code). It’s 4 miles from the Strip, with a $15 taxi ride or $4 shuttle to downtown. My 2023 trip from LAS to the Bellagio took 12 minutes and cost $14. Avoid flying into Henderson (HND)—it’s a private airport with no commercial flights.
A: No—SFO-LAS flights cost $150+ round-trip versus $58 for JFK-LAS in April. My May 2024 SFO-LAS trip was $165, $107 more than a direct LAS flight.
A: Book 3-6 weeks out for April-August. My April 2024 fare was $48 when booked 3 weeks early; booking 1 week out cost $89. Spirit’s cheapest fares vanish within 2 weeks of departure.
A: Southwest includes two free bags under 1500 miles for $149 flights. Spirit and Frontier charge $65+ for the first checked bag. I paid $130 for two bags on a $48 Spirit flight—never skip the online bag fee.
