✈️ Flight Guide: New York (JFK) → Las Vegas (LAS)

December in Las Vegas brings major draws such as holiday residencies and performances, special seasonal Cirque du Soleil shows, and New Year’s Eve celebrations along the Strip that substantially increase arrivals at Harry Reid International Airport (LAS). The National Finals Rodeo (NFR) also traditionally drives demand for flights from John F. Kennedy International Airport (JFK) to LAS in early December. These events can create surge pricing for hotels and ground transport, so buy event tickets early and reserve airport transfers or rideshares in advance. Use SEO phrases like "Las Vegas New Year's flights" and "NFR Las Vegas flight demand" when searching for availability and deals.

The best times to fly from John F. Kennedy International Airport (JFK) to Harry Reid International Airport (LAS) in December are typically early December (first two weeks) and midweek departures during the month, when fares tend to be lower than the peak holiday window. Red-eye flights and early-morning departures often offer savings and fewer delays at JFK. Avoid flying on the Sunday after Christmas and New Year's Eve evening unless your plans require celebration on the Strip, as demand — and prices — spike. Use flexible-date searches and fare alerts with phrases like "best time to fly JFK LAS December" to capture price dips.

Nonstop flights from John F. Kennedy International Airport (JFK) to Harry Reid International Airport (LAS) are the fastest and reduce the risk of missed connections during December weather disruptions, typically taking about 5.5–6 hours.

For holiday travel, nonstop is often worth the premium for reliability and time savings; for tight travel budgets, look for well-timed connections with at least a 90-minute layover to allow for delays and re-clearing security if necessary.

American Airlines operates competitive nonstop and one-stop options with connections through its hubs and can have promotional fares during early December sales. Low-cost carriers may present cheaper base fares but factor in baggage and seat fees when comparing. For December travel, compare total price (including bags) and flight times, and check each airline’s holiday waiver policy in case of weather cancellations.

Pack layers for Las Vegas evenings and bring a warm jacket for outdoor New Year's Eve activities, while keeping most luggage lightweight to avoid checked-bag fees. Enroll in TSA PreCheck and consider CLEAR at John F. Kennedy International Airport (JFK) to reduce security wait times, especially during December holiday peaks.
