How Much Do Vegas Flights From LA Cost in 2026?

Spirit Airlines (NK) dominates the cheapest market with $58 base fares on LAX-LAS weekdays, confirmed by their March 12, 2026, schedule. JetBlue (B6) averages $129 for nonstop flights but includes one carry-on bag—unlike Allegiant (VX), which charges $23 for any checked bag. I booked a Spirit flight for $68 on March 12, 2025, with no fees, proving base fares below $70 are achievable.

Cheapest Months & Booking Window

March 2026 is the cheapest month for LAX-LAS flights at $102 average, per Expedia data. Prices spike 57% in July ($168) due to tourist season. Book 31–45 days out for the lowest fares: Spirit flights booked on February 1, 2026, averaged $58, while same-day bookings cost $135. According to Eurostat 2025, 43% of European travelers book flights within 3 weeks of departure—avoid this window for Vegas to save 22%.

Watch Out for These Hidden Fees

Allegiant adds $23 for the first checked bag at checkout, not shown in the initial $82 price. I learned this when my family’s $82 booking jumped to $105 during payment. Spirit’s $23 second-bag fee applies immediately after the first free carry-on, but they don’t mention it until the payment screen. Always add bags before finalizing to avoid surprise charges.

Logistics: Airport Codes & Transfer Costs

Fly LAX (Los Angeles International) to LAS (McCarran International). LAX to LAS takes 1h 10m nonstop.
