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 and United are offering great fares from many northern cities to the sunny Florida cities of Fort Lauderdale, Miami and Orlando from just $80 round-trip. There’s plenty of availability from Newark (EWR) and Washington, D.C. (IAD) on United and from Chicago (ORD) on American for departures from February through March 2017. Book this deal while it lasts, and before United introduces its basic economy fares on these flights.This is also a great opportunity to take advantage of the new Visa Infinite companion discount that comes with the Ritz-Carlton Rewards Credit Card.
