Flight deals from New York to Seattle

Direct flights departing from New York John F. Kennedy International Airport (JFK) or Newark Liberty International Airport (EWR) to Seattle-Tacoma International Airport (SEA) typically cover the 2,400-mile transcontinental journey in approximately six hours. Passengers traveling on these nonstop routes cross three time zones during the westward trip across the United States. Connecting itineraries through hubs like Chicago O'Hare or Detroit Metropolitan Wayne County Airport will extend the total New York to Seattle transit time by two to four hours. Delta Air Lines, Alaska Airlines, and JetBlue operate the majority of nonstop service between New York and Seattle. Delta maintains a large presence at both JFK and SEA, offering multiple daily frequencies for coast-to-coast travelers. United Airlines provides direct flights originating exclusively from EWR, while budget carriers like Sun Country occasionally run seasonal connecting routes between the New York metropolitan area and the Pacific Northwest. Passenger volume on the New York to Seattle corridor peaks during July and August when cruise ships depart from Pier 91 for Alaska. Late spring and early autumn also see heavy passenger traffic from New York due to favorable weather conditions in Washington State. Travelers seeking the lowest airfares on this specific transcontinental path should target January and February departures, as post-holiday demand drops significantly.

Travel tips

Arrive early for domestic flights

TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.

Pack a mixed carry-on

Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.

Ease jet lag on longer routes

On longer cross-country flights, adjusting your sleep schedule a day or two before departure and staying hydrated in flight can reduce jet lag on arrival.

Screenshot your confirmation

Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.

Check in online when it opens

Most airlines open online check-in 24 hours before departure — checking in early can help with seat selection and, on some airlines, boarding group assignment.
