Departing from Ontario (ONT) FAQs
Search flexible dates with a 21–60 day window and use fare calendars from major OTAs and airline websites. Compare low-cost carriers like Spirit and Frontier with legacy carriers during midweek departures for the best economy fares, and sign up for fare alerts to capture flash sales.
Peak months include March (spring break), June–August (summer travel), and December (holidays and New Year’s Eve), which typically raise economy fares significantly. If you can travel in January, February, or late October, you’ll often find lower base fares and more last-minute deals.
Travelers often connect from Las Vegas to Los Angeles, Phoenix, San Diego, Salt Lake City, San Francisco, Denver, and even international hubs like Mexico City and Toronto when booking cheapest economy routes. Use multi-city search tools to combine short hops with long-haul carriers for savings.
Yes — January often features post-holiday fare drops and special January sales from carriers servicing Las Vegas. Book early in the month and be flexible with midweek travel to secure the cheapest economy seats for January departures.
Las Vegas (All Airports) (LASA) includes major terminals with ground transit, rideshare pickup zones, and shuttle services. Allow 90–120 minutes for check-in and security during peak periods, and consider off-site economy parking or public transit for cheaper long-term parking.
March is high demand because of spring break and conventions, producing higher economy fares and fuller flights; book at least 30–60 days in advance and consider red-eye or early-morning flights to save money. Also expect longer security lines and limited last-minute seat availability.
Arriving at Las Vegas (Any) FAQs
Economy (ECONOMY) typically refers to the airline's base economy fare, which may exclude checked baggage and seat selection. Check the carrier's fare rules before booking and consider add-ons or bundled fares if you need baggage or preferred seats.
Common arrival destinations for budget economy routes include New York City, Los Angeles, Chicago, Toronto, and Mexico City; these hubs receive multiple daily economy flights from Las Vegas and other western U.S. cities. Use hub-based connecting flights to reach international destinations cheaply.
Yes — arriving in economy during January, February, and September often yields lower base fares and reduced demand. Avoid major holiday weeks and convention dates to maximize savings on arrival fares.
Early November can offer discounted economy arrivals before Thanksgiving demand spikes; monitor Black Friday and early-November sales for special arrival deals. If traveling for Thanksgiving, book at least 60 days in advance to avoid high fares.
Economy passengers follow the same customs and transfer procedures as other classes but may face longer queues at major international hubs. Use mobile passport options, global entry where available, and prioritize flights with ample connection time to avoid missed transfers.
Search multiple nearby airports, use radius searches on flight comparison tools, and consider ground transfers from secondary airports to save on arrival costs. In many metro areas, arriving at a secondary airport plus a short bus or train ride can be significantly cheaper than the primary airport.

Events & Festivals — How They Impact Economy Fares from LASA
Major events that drive up economy fares include CES in January, Memorial Day and Fourth of July weekends in summer, large music festivals, and the Formula 1 Las Vegas Grand Prix in November. During these events, flight inventory tightens and prices rise—plan far ahead or shift travel dates outside event windows to secure cheaper economy seats. Monitor local event calendars and set fare alerts 3–6 months before big events to lock in better prices. CTA: Check event dates and compare economy flight alternatives now to avoid premium fares.
Best Time to Fly — Las Vegas (All Airports) (LASA) to Economy (ECONOMY)
Generally, the best time to fly in the cheapest economy class from Las Vegas (All Airports) (LASA) is during January, February, and September when demand is low and carriers discount seats. Midweek departures (Tuesday–Thursday) and off-peak hours (red-eye or early morning) consistently produce lower fares. For holiday travel, reserve 60+ days in advance or consider traveling the week before/after peak holiday dates to save. CTA: Use flexible-date search and price alerts now to catch the best time to fly.
Direct vs. Connecting Flights — LASA Departures to Economy (ECONOMY)
Nonstop flights save time but often cost more than connecting options—especially during peak months like March and December. For absolute cheapest economy fares, connecting itineraries through major hubs (Los Angeles, Phoenix, Denver, Salt Lake City) can reduce fares significantly, particularly in off-peak months like January and September. If you value time or have tight connections, prioritize nonstop routes even at a premium. CTA: Compare nonstop vs. connecting prices for your travel month to determine the best value.
Airline Comparison for Economy Travelers from Las Vegas (All Airports) (LASA)

Southwest offers competitive economy pricing with two free checked bags and frequent promotional sales—often cheaper overall for families. Legacy carriers (American, Delta, United) may offer higher fares but include more amenities and broader connectivity, useful during high-demand months like December or March. For international economy travel, compare transborder carriers and hub connections for the best combined price. CTA: Compare total ticket costs across carriers for your travel month before booking.
