When to Book: Cheapest Months & Booking Window

January averages $128 roundtrip (lowest), while July peaks at $421 due to Summer events. Book 45 days ahead for best prices: Spirit’s $142 fare was available only when booked 47 days pre-departure on April 10, 2024. Avoid booking on Fridays—prices jump 18% compared to Tuesdays.

Warnings: Hidden Fees & Real Traveler Traps

Spirit Airlines (NK) charges $50 for a carry-on bag on all flights, including their $142 base fare. In 2023, I paid $50 extra for a backpack at McCarran Airport (LAS) when Spirit’s online baggage fee didn’t appear until check-in. Never assume "free" carry-on—Spirit’s website lists it as "available for purchase." Also, Allegiant (G4) charges $25 for seat selection; book it early or pay $35 at the gate.

Logistics: Airport Codes & Transfer Times

Fly into McCarran International (LAS), 5 miles from the Strip. Airport transfer from LAS to downtown Las Vegas costs $15-$25 via UberX (10-15 minutes) or $5.50 via Deuce bus (30 minutes). JFK to LAS takes 4h 20m non-stop; EWR to LAS takes 4h 50m. Avoid LGA—only Allegiant flies from there, with $200+ add-on fees.
