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.No need to gamble on these flight deals — Delta, American, United and JetBlue are offering flights from $206 round-trip to Sin City from various hubs across the eastern half of the country, including Chicago (ORD) New York (JFK), Newark (EWR), Miami (MIA) and Atlanta (ATL).
