We recommend you use Google Flights to find dates to fly, then book through an online travel agency, such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.Several domestic carriers are offering great deals on transcon flights. You can fly from New York (JFK) to Seattle (SEA) for as little as $236 round-trip on Alaska Airlines, but other destinations on the West Coast are available for low prices as well. These cheap fares are generally valid for departures from November 2017 through March 2018, though exact availability varies depending on on your origin and destination cities. We recommend using Google Flights to find an itinerary that works for you, and then complete your booking directly through the airline.Airline: Alaska, Delta, JetBlue, Virgin AmericaRoutes: JFK/BOS/FLL to SEA/SFO/LAX/SAN/LASCost: $236 round-tripDates: November 2017 - March 2018Booking Link: Orbitz or ExpediaPay With: The Platinum Card® from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (5x on airfare) or Chase Sapphire Preferred Card (2x on travel)Here are a few examples of what you can book:New York (JFK) to Seattle (SEA) for $236 round-trip on Alaska:Boston (BOS) to Los Angeles (LAX) for $246 round-trip on Virgin America:New York (JFK) to Las Vegas (LAS) for $252 round-trip on Delta (basic economy):Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
