November is a solid shoulder-season month to depart from Harry Reid International Airport (LAS) en route to Incheon International Airport (ICN). The cooler desert temperatures in Las Vegas make airport transfers easier and November fares to Seoul often reflect shoulder-season pricing unless Thanksgiving week drives demand. Nearby major cities served from LAS include Los Angeles (LAX), Phoenix (PHX), Salt Lake City (SLC), San Diego (SAN) and San Francisco (SFO), which are commonly used as connection points for flights to Asia.
Incheon International Airport (ICN) is Korea's primary gateway and handles international arrivals with efficient immigration, transit, and ground-transport options. In November, arriving travelers from Harry Reid International Airport (LAS) will find crisp weather, fewer tourists compared with peak autumn weekends, and excellent transport links into Seoul, Busan (via domestic connections), and Jeju Island. ICN also serves nearby major destinations such as Seoul city center, Incheon, Suwon, Busan and Jeju.
November in Las Vegas often features entertainment residencies, early holiday events and local concerts — expect increased airport traffic around big shows and sports weekends. In Seoul and the Incheon area, November highlights often include the Seoul Lantern or Light Festivals, late-autumn cultural markets, and weekend markets showcasing seasonal foods like roasted chestnuts; early November is prime for autumn foliage viewing. These festivals can make travel in November more rewarding but sometimes increase hotel demand, so book accommodations and flights early if attending specific events.
Early to mid-November is often the best time to fly LAS to ICN for pleasant weather in Seoul (autumn colors) and lower fares compared with peak October weekends and late-November holiday spikes. Fly mid-week to avoid higher weekend and Thanksgiving fares; early-morning or red-eye departures may also be cheaper. If your schedule is flexible, target a booking window of 6–10 weeks ahead to find the best balance of price and seat availability for November travel.
Direct (nonstop) flights from Harry Reid International Airport (LAS) to Incheon International Airport (ICN) are the fastest option when available, with typical flight times around 12.5–13.5 hours. However, nonstop options may be seasonal or limited in November. Connecting flights via hubs like Los Angeles (LAX), San Francisco (SFO), or Seattle (SEA) often open up more carriers and cheaper fares, but add layover time (commonly 3–8+ hours) and increase total travel time to 15–22+ hours. Choose nonstop for time savings and convenience; choose connecting flights for greater schedule flexibility and potential savings — especially during November shoulder-season sales.
Korean Air and Asiana Airlines are primary full-service carriers for LAS–ICN service when nonstop routes are available, offering transpacific amenities such as in-flight meals, entertainment, and generous baggage allowances. Major U.S. carriers (Delta, United, American) commonly provide one-stop itineraries via West Coast hubs; these can be competitive on price and loyalty-program credit. Low-cost carriers do not typically operate nonstop LAS–ICN transpacific flights, but mixing carriers on one-stop itineraries can reduce costs. For November travel, compare total travel time, baggage fees, and alliance status — and use carrier filters to find best-value options for your priorities.
Pack warm layers for Seoul in November — daytime can be mild but evenings are chilly, so include a warm coat and closed shoes. For flights from Harry Reid International Airport (LAS), aim to arrive 3 hours early for international departures during holiday periods; mid-week travel often reduces queues. Use a reliable transit card (T-money) for Seoul public transport, pre-book airport transfers if you arrive late, and purchase travel insurance for long-haul international trips. For the best November fares, set price alerts and be flexible with one-stop routes through LAX or SFO.
