Airfare deals are typically only available on limited dates. 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.

Earlier today we wrote about deals from the West Coast to Tokyo, but now we’re seeing an airfare war to Australia! American Airlines started the battle with some solid mid-$700 fares, but United has upstaged AA with mid-$600 fares to Sydney from all the American hubs, including the East Coast cities of Philadelphia, Charlotte and Miami.

If you’re looking for an early-year United mileage run, many of the United fares don’t require a minimum stay. However, there’s plenty to do “down under” so there’s no reason to turn around quickly unless you’re short on vacation time.

On United, you’ll get to fly the transpacific flights on United’s brand new 787-9 Dreamliner while American Airlines flights to Sydney will be on the Boeing 777-300ER.
