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.TPG has long raved about JetBlue Mint, and for good reason. The onboard experience is like no other domestic product and the fares are relatively cheap (compared to the legacy US airlines). Mint fares typically start at $599 one-way, or $1,198 round-trip, but as we’ve seen they’re sometimes offered for even less. If you act quickly, you can snag Mint seats between Boston (BOS) and Barbados (BGI) from $299 one-way. Alternatively, you can book a flight out of Boston (BOS) or New York (JFK) to cities like San Diego (SAN) or San Francisco (SFO) from $398 one-way. Or you can use JetBlue points, starting from as little as 20,900 points + $7 one-way.The discounted fares are available in either direction and are being offered for a wide range of dates through February 2019. The easiest way to find availability is to search for dates via Google Flights, then book on Orbitz, Expedia or directly with JetBlue. Remember, you’ll want to try to pick a seat in rows 2 or 4 to get your own closed-door suite.Airline: JetBlueRoutes: BOS/JFK to/from BGI/LAS/SAN/SEA/SFOCost: $299+ (or 20,900 points + $7) one-way in lie-flat business classDates: June 2018 – February 2019Booking Link: Orbitz, Expedia or directly with the airlinePay With: The Platinum Card® from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (5x on airfare plus excellent trip delay insurance) or Chase Sapphire Preferred Card (2x on travel)Here are a few examples of what you can book:Boston (BOS) to Barbados (BGI) for $299 one-way nonstop in September:Boston (BOS) to Barbados (BGI) for 20,900 points + $7 one-way nonstop in September:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
