November travel from Ontario International Airport (ONT) to Seattle-Tacoma International Airport (SEA) blends mild Southern California departures with typically wet and cool Seattle arrivals. Early November often yields the best prices and fewer crowds, while the Thanksgiving holiday (late November) drives up demand and fares. For November routes, consider nonstop options operated by Alaska Airlines and other carriers, compare mid-week departures for savings, and sign up for price alerts. Pack layers for Seattle weather on arrival, allow extra time for baggage and transportation during holiday peaks, and reserve ONT parking in advance to save time.
Arriving at Seattle-Tacoma International Airport (SEA) in November means preparing for cool, often rainy days and the start of holiday programming across the city. The Link light rail provides a fast link to downtown Seattle, and rideshare pick-up zones are well-marked—expect heavier demand around Thanksgiving. For November itineraries, include indoor attractions like the Seattle Art Museum, Pike Place Market seasonal offerings, and nearby cities such as Tacoma and Bellevue for shopping and events. Be mindful of earlier sunsets and rainy conditions when planning outdoor activities.
November in the Seattle region brings early holiday events, seasonal markets, and sports. Popular November experiences include the Pike Place Market seasonal stalls and late-November holiday markets, downtown tree lightings, and possible Seattle Seahawks home games if NFL scheduling aligns. Thanksgiving weekend draws shoppers to Bellevue and downtown Seattle for retail sales, while cultural venues like museums and theaters run special fall programs.
The best time to fly ONT to SEA in November is mid-week (Tuesday–Thursday) during early- to mid-November for the best balance of price and availability. Avoid peak holiday dates around Thanksgiving (typically the last Thursday of November and the adjacent days). Red-eye options are less common on this short route, so early morning departures can provide both lower fares and more on-time performance.
Nonstop flights between Ontario International Airport (ONT) and Seattle-Tacoma International Airport (SEA) are the fastest and most convenient option—typical flight time is around 2 hours 40 minutes. Connecting flights via hubs like LAX, SFO, or DEN can be cheaper but add travel time and increase risk of missed connections during the November holiday season. If you prioritize price, a one-stop may save money; if you prioritize reliability and speed, choose nonstop.
Alaska Airlines often offers the most frequent nonstop schedules between Ontario International Airport (ONT) and Seattle-Tacoma International Airport (SEA), with competitive fares and strong Pacific Northwest connectivity. Delta Air Lines and American Airlines may provide nonstop or one-stop options with varying pricing and seat configurations. When comparing carriers in November, look at total travel time, baggage fees, loyalty benefits (Mileage Plan, SkyMiles, AAdvantage), and onboard amenities—Alaska is frequently favored for route frequency and regional service on the West Coast.
Prepare for a wet and cool Seattle arrival by packing waterproof layers, a travel umbrella, and quick-dry clothing. Allow extra time for ground transport and baggage claim during Thanksgiving week, and consider purchasing flexible or refundable tickets if travel dates coincide with holiday surge. Monitor weather forecasts for Pacific Northwest storms and check airline delay notifications; if transferring through other hubs, build buffer time into your itinerary.
Typical nonstop flight time from Ontario International Airport (ONT) to Seattle-Tacoma International Airport (SEA) is approximately 2 hours 40 minutes to 3 hours. Carriers may schedule multiple daily flights—early morning, mid-day, and evening—giving travelers flexibility in November. During the Thanksgiving period, additional seasonal frequencies or changed schedules can occur. Common one-stop connections include Los Angeles (LAX), San Francisco (SFO), and Denver (DEN) when direct flights are sold out or priced higher.
To find cheap ONT to SEA flights in November, search flexible dates (±3 days) and consider mid-week departures in early November. Set fare alerts on Google Flights or Kayak, compare one-way vs round-trip pricing, and look for flash sales from carriers like Alaska Airlines, Delta, and American. Avoid booking during Thanksgiving week unless you need to travel then—prices spike. Use loyalty points, check adjacent airports (e.g., LAX for more options), and clear your browser cookies or use private browsing when comparing fares.
