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. However, if you’re using the American Express Platinum Card, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. 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.There’s nothing like some last-minute travel to add some spice to your life. If you agree, don’t hesitate to book these cheap flights to Reykjavik (KEF). We found a nonstop option from San Francisco (SFO) departing as soon as the June 24 (this Saturday) priced at just $260 round-trip. If you prefer a bigger planning window there are still plenty of low-cost options departing from other US cities including Boston (BOS), Chicago (ORD), Los Angeles (LAX), Miami (MIA) and Baltimore (BWI). Use Google Flights to find the dates you want, then book on Orbitz, Expedia or directly with the airline itself.Airlines: WOW AirRoutes: BOS/ORD/MIA/LAX/SFO/BWI to KEFCost: $260+ round-trip in economyDates: June through September 2017Booking Link: Orbitz or ExpediaPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (3x on airfare) or Chase Sapphire Preferred (2x on travel)Here are a few examples of what you can book:San Francisco (SFO) to Reykjavik (KEF) for $260 round-trip:Baltimore (BWI) to Reykjavik (KEF) for $260 round-trip:Boston (BOS) to Reykjavik (KEF) for $300 round-trip:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
