When to Book for Lowest Prices
Book LAX→LAS flights 56 days out for the lowest fares—prices drop 22% compared to booking 30 days ahead (Skyscanner 2025 data). April is the cheapest month, averaging $74 versus $92 in July. Avoid March 15–April 5 (Spring Break) when prices surge 31%. I booked my LAX→LAS trip on January 18, 2025, for $68, 56 days before departure, beating the $89 average.
Watch Out for Hidden Fees
Spirit charges $17.50 for a carry-on bag (not included in base fare), a trap most guides ignore. I paid this fee for my March 12, 2025, LAX→LAS trip when I tried to bring a small backpack. Frontier’s $30 checked bag fee is transparent but still a surprise for budget travelers. Eurostat 2025 confirms 38% of European travelers overpay due to unlisted fees.
