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.Attention LA-based travelers: several full-service carriers are offering fares to London (LHR) from just $487 round-trip, with availability in May (very limited dates) and then again from September through the end of the schedule in March of 2018. You can choose nonstop flights with American Airlines, United and Delta/Virgin Atlantic, and since they’re full-service carriers you’ll have complimentary meals, checked bags and seat selection. Since so many flights are offered on a wide variety of dates, be sure to find your flights on Google Flights first, and then complete booking directly with the airline.Airline: American, Delta, United and Virgin AtlanticRoute: LAX to LHRCost: $487 round-trip in economyDates: May 2017; September 2017 - March 2018Booking Link: OrbitzPay 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:Los Angeles (LAX) to London (LHR) for $487 round-trip on American:Los Angeles (LAX) to London (LHR) for $487 round-trip on United:Los Angeles (LAX) to London (LHR) for $487 round-trip on Delta/Virgin Atlantic:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
