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.If you’re feeling the winter blues and ready for a wild weekend in Sin City, United Airlines is offering discounted fares on flights to Las Vegas (LAS) from Chicago (ORD) and Newark (EWR). Fares start as low as $127 from the East Coast cities, and if you’re based on the West Coast, you could grab flights as low as $60 from San Francisco (SFO) and $98 from Los Angeles (LAX) on either United or Virgin America. Availability is fairly limited on dates from February and March 2017 so you’ll definitely want to use Google Flights to find your desired dates, and then you can complete booking on the airline’s site.Airline: United Airlines, Virgin AmericaRoute: EWR, LAX, ORD and SFO to LASCost: $60+ round-trip from West Coast in economy; $127+ round-trip from East CoastDates: February - March 2017Booking Link: Orbitz or ExpediaPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (3x on airfare) or Chase Sapphire Preferred (2x on travel)Here are a few examples of what you can book:Chicago (ORD) to Las Vegas (LAS) for $126 round-trip:Newark (EWR) to Las Vegas (LAS) for $186 round-trip:San Francisco (SFO) to Las Vegas (LAS) for $60 roundtrip:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
