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.Tickets to Johannesburg typically range from $1,800 and up, but this Virgin Atlantic sale slashes nearly $1,200 off the going rate. Sale fares begin in October, but the lowest rates are widely available between November 2018 and March 2019.Note that Google Flights works for searching specific dates and rates, but does not actually link to a Virgin Atlantic booking page. So you will have to use Google Flights first to find the dates you want, then repeat the process on Virgin Atlantic in order to actually book your tickets.Airline: Virgin AtlanticRoutes: LAX/SFO/JFK to JNBCost: $676+ round-trip in economyDates: November 2018 to March 2019Booking Link: Kayak for Hong Kong Airlines flights.
