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 Platinum Card® from American Express, you’ll need to book directly with the airline or through the 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 familyNever flown Mint? Now’s your chance, as JetBlue’s premium business-class product is pricing out as cheaper than economy on at least one route to the Caribbean. On some dates through the end of the year and into 2019, you can find one-way prices from Boston (BOS) to Aruba (AUA) for cheaper than economy — for $301.Not only are some fares between BOS and AUA cheaper than economy, but we’re also seeing some low Mint fares on other Caribbean routes. Though they may not be cheaper than economy, they’re still worth giving a look — especially if you’ve been eyeing a Mint flight.Mint is JetBlue’s premium product, flown on select transcontinental and Caribbean routes. Widely regarded as one of the best domestic business-class products (it’s TPG’s favorite way to fly across the country), Mint offers lie-flat seats and a refreshing take with its soft product. Remember, if available, you’ll want to select rows 2 or 4 for the throne, closed-door suites.To book, head to Google Flights and search the route that’s best for you. Then, select date(s) and scroll through the calendar for travel times and prices that work.
