Qantas does not offer its credit cards to the U.S. residents indeed. However, there is always a way out. Most major U.S. banks offer travel rewards credit cards that will allow you to earn miles rewards on all your purchases, including on flights with Qantas. So when you do not fly with Qantas, you will be able to continue earning miles while shopping at local stores. The miles accumulated on a travel rewards credit card can be redeemed for travel expenses like airline tickets, hotel rooms, and car rentals without restrictions and limits. The only condition is your airline ticket should be bought with this travel rewards credit card.
