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.Norwegian’s currently offering cheap flights to popular European cities from NYC. Fly from Newark or JFK to Barcelona (BCN), Copenhagen (CPH) or Berlin (SXF) for around $300 round-trip, or go to Rome (FCO) for as little as $360 round-trip — a deal we rarely see! As is often the case with Norwegian, the best deals are found by booking outbound and return flights on separate itineraries.
