Airfare deals are typically only available on limited dates. 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 family.
