If you fly once a year with Virgin, this card might be useful. The card is currently offering 3 different choices (see website).
Specifically, offer 2 provides benefits for anyone stoozing / repeating balance transfers.
0% for 12 months from application on all purchases.
0% for 6 months on balance transfers (up to 80% of credit limit), with no BT fee.
$129 annual fee rebated with a $129 virgin flight voucher.
Minimum credit limit of $6000 / Annual income required of $35000*
This combination effectively allows you to instantly load the card to 80% from another card that might have an offer expiring and then allow you to continue to make purchases up to the limit. Just remember to pay down all of the original Balance Transfer amount before the 6 months is reached and then continue spending up until 12 months, before rinsing and repeating the process with the next card.
*edit typo
