Arriving at Las Vegas (LAS) FAQs
The label 'Economy Class — Cheapest Arrival (ECO)' refers to searching for the lowest-priced economy-class fares and arrival options across carriers and airports. It prioritizes cheapest fare classes, including basic economy, and routes with affordable connections. When booking, check baggage and change fee policies because the lowest economy fares often have stricter rules.
When seeking the cheapest economy arrivals, travelers often consider nearby hubs and top destinations like New York City, Orlando, Miami, Chicago, and Los Angeles to leverage competitive fares and more connections. Using these major cities as arrival alternatives can lower total trip costs and open better flight schedules. Compare total travel time and transfer costs when choosing alternate arrival cities.

In December, holiday travel spikes reduce availability of the cheapest economy arrivals and raise prices on peak days around Christmas and New Year’s Eve. To secure affordable December economy arrivals, book early, travel on shoulder dates, or choose alternate arrival cities with lower demand. Monitor fare alerts and consider flying early in the month when possible.
Year-round strategies to find the cheapest economy arrivals include using flexible date searches, subscribing to fare alerts, booking 6–10 weeks in advance for domestic flights, and considering midweek or red-eye flights. Mix-and-match airlines and using open-jaw or multi-city searches can reveal lower-priced arrivals as well. Always review baggage fees and ancillary costs to compare true door-to-door prices.
Yes, the cheapest economy fares—often labeled basic economy—commonly limit or exclude seat selection and checked baggage, and sometimes even carry-on allowance. If seat choice or baggage is important, compare regular economy with bundled options to determine the best value. Read fare rules at booking and factor ancillary fees into the total price to avoid surprises.
