We recommend that 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.American Airlines is running a great sale between the east coast cities and San Francisco (SFO) starting at just $103 round-trip for Basic Economy or $143 round-trip for Main Cabin.
