Fortunately, you have other options apart from getting a Singapore Airlines card. You can get a travel rewards credit card and earn miles on all airlines you fly. Such cards usually give you increased rewards on all travel purchases as well as a large sign-up bonus. Miles usually don't expire and are easy to redeem. For example, the Discover it® Miles has no annual fee for the life of the account, so you won't have to pay for the rewards. As for the rewards, you earn them on all purchases. Not only can you put all your travel expenses on that credit card, but also your grocery shopping or dining. All the miles earned during the first year will be matched at the end of the first year (if you are a new cardmember). For example, if you earn 35,000 miles, you will get 70,000 miles. Moreover, the card has no annual fee and all the miles you've earned will never expire.
